Ross (optics) Lens

Filed under: Uncategorized — admin @ 4:42 am

Ross is the name of a succession of London-based lens designers and their company.

Andrew Ross (1798–1859) founded his company in 1830, from 1840 producing camera lenses signed “A. Ross”. Particularly during Andrew Ross’s lifetime, the company was one of the foremost lens companies. In the twentieth century, Ross continued to produce lenses, but also produced binoculars, epidiascopes, etc.

After World War II Ross produced lenses for Ensign, MPP, and other cameras.

Ross was taken over by Avimo in 1975; Avimo was later taken over by Thales Optics.

Spreader bar wearer’s

Filed under: Uncategorized — admin @ 9:53 pm

A spreader bar is a physical restraint used in bondage play. It is a stiff bar typically two to three feet (sixty to ninety cm) long, though some can telescope to varying lengths, with attachment points for restraints at each end. They may include extra attachment points along their length for collars, suspension play, or as anchoring points for ropes or chains. Not all spreader bars, however, are designed to support the weight of a person.

When worn on the wrists, a spreader bar serves to hold the arms spread away from the body to provide unimpeded access to the torso. When worn on the ankles or between the knees, it immobilizes the wearer by preventing all but the most awkward walking while spreading the legs and allowing free access to the wearer’s groin. A pair of spreader bars may hold the wearer in a spreadeagle position. If there are bars between the knees and between the ankles, the wearer may be forced to bend their knees, making walking even harder.

A spreader bar that fastens to the neck and wrists is a yoke.

Objective (optics) lenses

Filed under: Uncategorized — admin @ 6:51 pm

An objective in optics is the lens or mirror in a microscope, telescope, camera or other optical instrument that receives the first light rays from the object being observed. The objective is also called the object lens, object glass, and objective glass.

Microscope objectives are typically designed to be parfocal, which means that when one changes from one lens to another on a microscope, the sample stays in focus. Microscope objectives are characterized by two parameters, namely, magnification and numerical aperture. The former typically ranges from 5X to 100X while the latter ranges from 0.14 to 0.7, corresponding to focal lengths of about 40 to 2 mm, respectively. For high magnification applications, oil-immersion objective has to be used. The objective is specially designed and has to be immersed in refractive index matching oil (an index-matching material).

Photographic zoom lenses may also be parfocal, so that one can change the magnification without having to refocus.

Knapp’s Rule Lens

Filed under: Uncategorized — admin @ 2:34 pm

Knapp’s Rule states that lenses placed at the anterior focal point of the eye, generally 15 mm in front of the eye, will create similarly sized images on the retina, whenever the disparity between the two eyes is due to a difference in axial length of the eyes.

When a refractive error is corrected with spectacle lenses, the retinal images change size. It is magnified with convex lenses and minified with concave lenses. One difficulty, then, in prescribing glasses to an individual with a disparity in refractive error between the two eyes is that a disparity in image size between the two eyes may be created.

There is some controversy as to the soundness of Knapp’s Rule.

Cooke triplet lenses

Filed under: Uncategorized — admin @ 11:36 pm

The Cooke triplet is a photographic lens design designed and patented in 1893 by Dennis Taylor who was employed as chief engineer by Cooke of York. It was the first lens system that allows elimination of most of the optical distortion or aberration at the outer edge of lenses.

A Cooke triplet comprises a negative flint glass element in the centre with a crown glass element on each side. In this design, the sum of all the curvatures times indices of refraction can be zero, so that the field of focus is flat. In other words, the negative lens can be as strong as the outer two combined, when one measures in diopters. Yet the lens will converge light, because the rays strike the middle element close to the optic axis. The curvature of field is determined by the sum of the diopters, but the focal length is not.

It was at that time a major advancement in lens design. The triplet design was made obsolete by later designs on high end cameras, but remains widely used up to this day on cheap cameras.

Despite the fact that the Cooke design was patented in 1893 it seems that the use of achromatic triplet designs in astronomy appeared as early as 1765. The 1911 encyclopedia Britanica wrote:

The triple object-glass, consisting of a combination of two convex lenses of crown glass with a concave flint lens between them, was introduced in 1765 by Peter, son of, John Dollond, and many excellent telescopes of this kind were made by him.

A similar design is used in the strong focusing synchrotron, invented first by Nicholas Christofilos in 1949, but his work was not known in the U.S., where parallel development took place.

Smallville: Chloe Chronicles ACUVUE

Filed under: Uncategorized — admin @ 3:37 pm

Smallville: Chloe Chronicles is a spin-off series from Smallville. The series revolves around the character of Chloe Sullivan (played by Allison Mack). The first two series pick up after the events of the season one episode of Smallville, Jitters. The third season, known as Smallville: Vengeance Chronicles is a spin-off from the season five episode “Vengeance”, with Chloe meeting Andrea Rojas or the “Angel of Vengeance” (played by Denise Quiñones). Most episodes have a duration of a few minutes, and are only available online and through the Smallville DVD releases.

Contents


Chloe Chronicles

The first volume of Chloe Chronicles details Chloe’s investigation into “Level 3″ at the Smallville LuthorCorp plant after the events of Jitters. In her first video, Chloe lays out her mission statement: dig up evidence regarding a deceased LuthorCorp employee named Earl Jenkins. Chloe interviews Jenkins’ widow, who explains the history of her husbands ‘jitters’ and when they began to occur. She also showed Chloe a pair of Jenkins’ shoes he used while at work, with the bottom of them clearly covered in meteor dust (kryptonite).

Chloe thinks that Jenkins’ violent tremors and eventual death are linked to prolonged exposure to meteor dust (kryptonite). She tracks the meteor experiments back to a company called Nu-Corp and finds an ex-scientist, Dr. Arthur Walsh, now teaching high-school biology. Chloe understands that he is willing to turn over information about what happened to Earl. However Dr. Walsh vanishes before Chloe can interview him again. In video three, Chloe interviews Jamison, who she suspects of cashing in on the project, as he now holds a high position at Nu-Corp.

Jamison denies the claims regarding research into meteor rock, and claims it is only Walsh’s imagination. Jamison grows tired of Chloe’s accusations and ends the interview. However, when Chloe goes back to visit Walsh, his office is empty and he is nowhere to be found. Before Chloe leaves, she accepts a package on his behalf, containing a large sum of cash. The note is anonymous, and she later finds out that the delivery company does not exist. Chloe gives the money to Jenkins’ family.


Chloe Chronicles, Vol II

Bix, an ex-navy seal and former member of the LuthorCorp’s “Deletion Group,” contacts Chloe with a cryptic riddle from the missing Arthur Walsh. Chloe decides to keep digging, realizing that innocent lives depend on her. Walsh, who was earlier presumed dead, sends her several videos which lead her to the grave of Sarah Stromberg, a journalism student at Metropolis University with whom Walsh was involved. Chloe finds out that Walsh, Donovan Jameson (head of Nu-Corp), and the late Dr. Stephen Hamilton all worked together on meteorite experiments. Chloe feels that Sarah Stromberg is a kindred spirit and resolves to get justice for her.

Chloe, with Pete as her camera crew, sneaks into Jameson’s underground lab where Jameson explains that he has been experimenting on dead meteor freaks, including Sean Kelvin, Greg Arkin, and Tina Grier. While Jameson claims to have benevolent reasons for his research, Chloe finds videotape proof implicating Jameson in Sarah Stromberg’s death after she got too close to revealing his experiments.

Walsh apparently knew about Jameson and confronted him about his involvement. It is implied that Jameson then murdered Walsh. When Jameson discovers the incriminating surveillance tape, he attacks Chloe. Exhibiting the same “jitters” as Earl Jenkins, Jameson then reveals he is in fact researching the meteor freaks in order to inherit their powers. Pete and Chloe flee from the murderous Jameson and Chloe throws a hydrogen tank at him to slow him down. Jameson’s arm is vibrating too fast from the tremors and the tank explodes, killing him and setting the lab ablaze.

At the end of the Chronicles, Chloe and Pete flee the burning building only to get sidelined by Lionel Luthor’s passing limousine. Realizing Lionel was funding Jameson from the beginning, Chloe vows to bring him down. Lionel responds with a veiled threat, but lets Chloe and Pete go when he realizes they have no evidence to implicate him. In the end, Chloe decides against revealing the details of Walsh’s involvement with Nu-Corp and Sarah to protect his family. Nu-Corp collapses and Level 3 seemingly ceases to exist.


Vengeance Chronicles

In this spinoff of the Smallville episode “Vengeance”, Chloe joins forces with a costumed vigilante whom she dubs the “Angel of Vengeance”. In reality, it’s her mild-mannered co-worker Andrea Rojas. Andrea killed the man who murdered her activist mother, and made an attempt on Lionel Luthor’s life for his involvement in the crime. On the run, Andrea turns to Chloe for help when Lionel’s newly reformed “Deletion Force” begins pursuing her relentlessly. Andrea Rojas is also the real name of Acrata, a DC Comics character with a different back story and different abilities. In addition, the Smallville Andrea mentions that her mother was part of an organization called Acrata.

The chronicles start off with Chloe at the Daily Planet, where she is aproached by Rojas, asking her for help. Rojas tells Chloe everything that happened (in “Vengeance”) and how after, she gave up her mask after being on the run, and went home, though there were men waiting for her, who are out to get all super-powered people in Metropolis. A man with electric powers - Nick Yang, saves Rojas, and then after pursuing her, convinces her to follow him to safety, to the sewers, where Molly Griggs (Delete) is also hiding out.

There they explain that Lex Luthor, rather than disband his father’s project, has expanded Level 3 into Level 33.1. It’s a subproject using superpowered mutants to expand LuthorCorp’s technology, including Griggs, Yang, Bart Allen (the future Flash in Run), and Mikhail Mxyzptlk (Jinx). Yang and Griggs had been tracking Rojas as they knew she would have been on the list. It is after this that Rojas, wanting to get a normal life back, aproaches Chloe for help - to expose Level 33.1.

Rojas, Yang and Griggs break into Lex’s mansion, where Griggs begins work on her computer. However, Rojas begins to question what she is doing, and upon realizing that Griggs is installing another lethal program into his computer, she trys to stop them. Yang trys to prevent her, but has a change of heart and destroys the computer. Rojas and Chloe meet up on the rooftop of a building in Metropolis where she thanks her for being a good friend, and tells her that the Angel of Vengeance will continue. As a siren is heard in the background, Rojas leaps off the rooftop into the night.

Vision Express contact lenses

Filed under: Uncategorized — admin @ 7:09 am

Vision Express is a leading High Street optician in the United Kingdom, selling glasses and contact lenses. The company’s selling point is glasses in 1 hour. The company opened its first store in 1988 at the MetroCentre. After buying out LensCrafters’ UK base, they further increased their number of stores.

As of 2006 it has over 220 stores across the UK. These stores are divided into four types: Optical Lab, Superstores, Franchises (owned entirely by the proprietor but under licence to use the Vision Express name and with some access to Grand Vision services) and Joint Ventures (premises owned entirely by proprietor, but setup cost subsidised by Vision Express).
The stores are then further divided by an ongoing refit program within the company, changing from the predominantly white fitments of the Optical Lab to the so called Zarna concept, which employs softer lighting with warm browns and oranges.
The first two types of store which provide a one hour service using both semi-finished lenses (prescription being cut from scratch) and stock lenses. The JV stores tend to provide an overnight service also with some exceptions.

Their headquarters are in Lenton, Nottingham.

Their parent company GrandVision has stores under various brands across Europe, and the rest of the world.

Its rivals in UK include Specsavers.

Under franchise agreement there is a strong Vision Express brand present also in Latvian and Lithuanian markets. These shops were acquired from GrandVision by Latvian entepreneurs of “LU Optometrijas Centrs SIA”.

Lens sag Contact Lens

Filed under: Uncategorized — admin @ 12:49 am

Lens sag is a problem that sometimes afflicts very large refracting telescopes. It is the equivalent of mirror sag in reflecting telescopes. It occurs when the physical weight of the glass causes a distortion in the shape of the lens because the lens can only be supported by the edges. A mirror on the other hand can be effectively supported by the entire opposite face, making mirror sag much less of a problem. One expensive solution to lens sag is to place the telescope in orbit around the Earth.

Northern Ireland general election, 1949 Summary and

Filed under: Uncategorized — admin @ 5:16 am

The Northern Ireland general election, 1949 was held on 19 February 1949. The election became known as the Chapel-gate election because collections were held at churches in Eire to support the Nationalist Party campaign.

The election was held just after the Republic of Ireland’s declaration of a republic. The Unionists were able to use their majority in the Parliament of Northern Ireland to schedule the election at a time when many Protestants felt uneasy about development south of the border and as a result might be more likely to vote Unionist than for Labour candidates. This appears to have been bourne out in the collapse of the Labour vote.

All parties shown. The only Socialist Republican Party candidate was elected unopposed.

Doublet (lens) Lens

Filed under: Uncategorized — admin @ 10:15 pm

In optics, a doublet is a type of lens made up of two simple lenses attached together. The lenses are made from glasses with different refractive indices and different amounts of dispersion. Often one element is made from crown glass and the other from flint glass. This combination produces a better image than a simple lens. Trilobites, which are now extinct, had natural doublet lenses.

Doublets can come in many forms, though most commercial doublets are achromats, which are optimized to reduce chromatic aberration while also reducing spherical aberration and other optical aberrations. Apochromats can also be made as doublets.

In a cemented doublet, the lenses are held together by an adhesive, such as Canada balsam or epoxy. Some doublets use no adhesive between the lenses, relying on external fixturing to hold them together. These are called air-spaced doublets.

Amaurophilia ACUVUE Contact Lenses

Filed under: Uncategorized — admin @ 6:35 am

Amaurophilia is the preference for sexual intercourse with partners who are blind or blindfolded.<ref>The Encyclopedia of Unusual Sex Practices ISBN 0-942637-64-X). The “Amaurophilia” entry is excerpted online</ref> This type of sexual activity may also be conducted by engaging in sexual intercourse in complete darkness.<ref>Amaurophilia at AbbreviationDictionary</ref>

Amaurophiliacs are extremely rare, but some will do simulation play with sleepshades; blindfolds or eye patches; or vision-restricting contact lenses, either worn or given to partners to wear. Some amaurophiliacs may even extend this play outside of sex through the use of blindfolds or contact lenses in conjunction with a white cane for mobility. Some amaurophiliacs may choose to learn Braille in order to enhance their experience during play sessions.

Amaurophilia is also the name of a track on the IDM album Nymphomatriarch by Venetian Snares.

Lowsider contact

Filed under: Uncategorized — admin @ 5:06 am

The lowsider or lowside is a type of motorcycle accident usually occurring in a curve and most often caused by either locking wheel due to excessive braking or accelerating too hard out through a corner.


Behaviour leading to a lowsider and physical explanation

All forces occurring between the motorcycle and the road (such as accelerating, decelerating and steering) are transmitted by friction occurring in the contact patch. There is a limited amount of force the contact patch can transmit before the tire begins to slide.

If the driver makes a curve on a motorcycle, the driver applies a force on the motorcycle, causing it to alter its course. This force is transferred to the motorcycle through the contact patch. Braking within a curve will increase the stress in the contact patch, because now there is an additional force which also has to be transmitted through the contact patch. This additional amount of force may cause the tire to slide and lock. If braking is applied equally to both tires, the rear tire will begin to slide first because braking causes a weight shift towards the front tire, improving its contact with the road while lessening the rear tire’s grip.

Once a tire slips in a curve, it will move outwards under the motorcycle and cause the cycle to lay down in the direction the driver is already leaning to counteract the centrifugal force. Unless this movement is counteracted, the motorcycle will lay down and slide outwards. Counteracting this movement by reducing brake force may lead to a highsider.

The name derives from the fact that it is usually the inward side the motorcycle will fall on (or the side that points downward in a curve, the low side).

Drivers are usually advised to do a lowsider rather than a highsider if neither can be avoided. The lowsider has the advantage of the motorcycle sliding before the driver, thus not threatening to crush him.

Scribonius Largus Prescriptions

Filed under: Uncategorized — admin @ 12:38 am

Scribonius Largus was the court physician to the Roman emperor Claudius.

About 47 AD, at the request of Gaius Julius Callistus, the emperor’s freedman, he drew up a list of 271 prescriptions (Compositiones), most of them his own, although he acknowledged his indebtedness to his tutors, to friends and to the writings of eminent physicians. Certain traditional remedies are also included. The work has no pretensions to style, and contains many colloquialisms. The greater part of it was transferred without acknowledgment to the work of Marcellus Empiricus (c. 410), De Medicamentis Empiricis, Physicis, et Rationabilibus, which is of great value for the correction of the text of Largus.

See the edition of the Compositiones by S. Sconocchia (Teubner 1983), which replaced the well-outdated edition of G. Helmreich (Teubner 1887).

Benjamin Franklin Bifocal

Filed under: Uncategorized — admin @ 8:46 pm

Benjamin Franklin ( – April 17 1790) was one of the most important Founding Fathers of the United States. He was a leading author, political theorist, politician, printer, scientist, inventor, civic activist, and diplomat. As a scientist he was a major figure in the history of physics for his discoveries and theories regarding electricity. As a political writer and activist he, more than anyone, invented the idea of an American nation,<ref> “Benjamin Franklin: America’s Inventor” article from HistoryNet.com</ref> and as a diplomat during the American Revolution, he secured the French alliance that helped to make independence possible.

Franklin was famous for his curiosity, his writings (popular, political and scientific), his inventions, and his diversity of interests. As a leader of the Enlightenment, he gained the recognition of scientists and intellectuals across Europe. An agent in London before the Revolution, and Minister to France during the war, he, more than anyone else, defined the new nation in the minds of Europe. His success in securing French military and financial aid was a great contributor to the American victory over Britain. He invented the lightning rod, bifocals, the iron furnace stove (also known as the Franklin stove), a carriage odometer and a musical instrument known as the armonica. He was an early proponent of colonial unity. Many historians hail him as the “First American.”

Born in Boston, Massachusetts, Franklin learned printing from his older brother and became a newspaper editor, printer, and merchant in Philadelphia, becoming very wealthy. He spent many years in England and published the famous Poor Richard’s Almanac and the Pennsylvania Gazette. He formed both the first public lending library and fire department in America as well as the Junto, a political discussion club. During this period he wrote in favor of paper money, against mercantilist policies such as the Iron Act of 1750, and also drafted, in 1754, the Albany Plan of Union, which would have created a continental legislature; demonstrating how early he conceived of the colonies as being naturally one political unit.

Franklin became a national hero in America when he spearheaded the effort to have Parliament repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco-American relations. From 1775 to 1776, Franklin was Postmaster General under the Continental Congress and from 1785 to 1788 was President of the Supreme Executive Council of Pennsylvania. Toward the end of his life, he became one of the most prominent abolitionists.

Franklin was interested in science and technology, carrying out his famous electricity experiments and inventing—in addition to the lightning rod—the Franklin stove, catheter, swimfins, glass harmonica, and bifocals. He also played a major role in establishing the University of Pennsylvania and Franklin and Marshall College. He was elected the first president of the American Philosophical Society, the oldest learned society in the United States, in 1769. Fluent in five languages, he is generally recognized as a polymath.

Biography


Ancestry

Franklin’s father, Josiah Franklin, was born at Ecton, Northamptonshire, England on December 23, 1657, the son of Thomas Franklin, a blacksmith and farmer, and Jane White. His mother, Abiah Folger, was born in Nantucket, Massachusetts, on August 15, 1667, to Peter Folger, a miller and schoolteacher and his wife Mary Morrill, a former indentured servant. A descendant of the Folgers, J. A. Folger, founded Folgers Coffee in the 19th century.

Ben Franklin’s great-great-grandmother was Alice Elmy from Diss on the Suffolk / Norfolk border in England.

Around 1677, Josiah married Anne Child at Ecton, and over the next few years had three children. These half-siblings of Benjamin Franklin included Elizabeth (March 2, 1678), Samuel (May 16, 1681), and Hannah (May 25, 1683).

Sometime during the second half of 1683, the Franklins left England for Boston, Massachusetts. They had several more children in Boston, including Josiah Jr. (August 23, 1685), Ann (January 5, 1687), Joseph (February 5, 1688), and Joseph (June 30, 1689) (the first Joseph died soon after birth).

Josiah’s first wife, Anne, died in Boston on July 9, 1689. He was married to Abiah Folger on November 25, 1689 in the Old South Meeting House of Boston by Samuel Willard.

Josiah and Abiah had the following children: John (December 7, 1690), Peter (November 22,1692), Mary (September 26, 1694), James (February 4, 1697), Sarah (July 9, 1699), Ebenezer (September 20, 1701), Thomas (December 7, 1703), Benjamin (January 17, 1706), Lydia (August 8, 1708), and Jane (March 27, 1712).


Early life

Benjamin Franklin was born on Milk Street in Boston on January 17, 1706 [1] and baptized at Old South Meeting House. His father, Josiah Franklin, was a tallow chandler, a maker of candles and soap, whose second wife, Abiah Folger, was Benjamin’s mother. Josiah’s marriages produced 17 children; Benjamin was the fifteenth child and youngest son. Josiah wanted Ben to attend school with the clergy but only had enough money to send him to school for two years. He attended Boston Latin School but did not graduate; he continued his education through voracious reading. Although “his parents talked of the church as a career” for Franklin, his schooling ended when he was ten. He then worked for his father for a time and at 12 he became an apprentice to his brother James, a printer. When Ben was 15, James created the New England Courant, the first truly independent newspaper in the colonies. When denied the option to write to the paper, Franklin invented the pseudonym of ‘Mrs. Silence Dogood’ who was ostensibly a middle-aged widow. The letters were published in the paper and became a subject of conversation around town. Neither James nor the Courant’s readers were aware of the ruse, and James was unhappy with Ben when he discovered the popular correspondent was his younger brother. Franklin left his apprenticeship without permission and in so doing became a fugitive.<ref> Van Doren (1991)</ref>

At age 17, Franklin ran away to Philadelphia, Pennsylvania, seeking a new start in a new city. When he first arrived he worked in several printer shops around town. However, he was not satisfied by the immediate prospects. After a few months, while working in a printing house, Franklin was convinced by Pennsylvania Governor Sir William Keith to go to London, ostensibly to acquire the equipment necessary for establishing another newspaper in Philadelphia. Finding Keith’s promises of backing a newspaper to be empty, Franklin worked as a compositor in a printer’s shop in what is now the Church of St Bartholomew-the-Great in the Smithfield area of London. Following this, he returned to Philadelphia in 1726 with the help of a merchant named Thomas Denham, who gave Franklin a position as clerk, shopkeeper, and bookkeeper in Denham’s merchant business.<ref> Van Doren (1991)</ref>

In 1727, Benjamin Franklin, at age 21, created the Junto, a group of “like minded aspiring artisans and tradesmen who hoped to improve themselves while they improved their community.” The Junto was a discussion group for issues of the day; it subsequently gave rise to many organizations in Philadelphia.

Reading was a great pastime of the Junto, but books were rare and expensive. The members created a library, and at first they pooled their own books together. This did not work, however, and Franklin came up with the idea of a subscription library, where the members pooled their monetary resources to buy books. This idea was the birth of the Library Company, and the charter of the Library Company of Philadelphia was created in 1731 by Franklin.

Originally, the books were kept in the homes of the first librarians, but in 1739 the collection was moved to the second floor of the State House of Pennsylvania, now known as Independence Hall. In 1791, a new building was built for the library specifically. The Library Company flourished without any competition and gained many priceless collections from bibliophiles such as James Logan and his physician brother William. The Library Company is now a great scholarly and research library because of its 500,000 rare books, pamphlets, and broadsides, more than 160,000 manuscripts, and 75,000 graphic items.

Upon Denham’s death, Franklin returned to his former trade. By 1730, Franklin had set up a printing house of his own and had contrived to become the publisher of a newspaper called “The Pennsylvania Gazette”. The Gazette gave Franklin a forum for agitation about a variety of local reforms and initiatives through printed essays and observations. Over time, his commentary, together with a great deal of savvy about cultivating a positive image of an industrious and intellectual young man, earned him a great deal of social respect; though even after Franklin had achieved fame as a scientist and statesman, he habitually signed his letters with the unpretentious ‘B. Franklin, Printer’.<ref> Van Doren (1991)</ref>

Franklin was initiated into the local Freemason lodge in 1731 and became a grand master in 1734, indicating his rapid rise to prominence in Pennsylvania.<ref name=HC>The History Channel, Mysteries of the Freemasons: America, video documentary, August 1, 2006, written by Noah Nicholas and Molly Bedell</ref><ref>http://freemasonry.bcy.ca/biography/franklin_b/franklin_b.html</ref> That same year, he edited and published the first Masonic book in the Americas, a reprint of James Anderson’s The Constitutions of the Free-Masons. Franklin remained a Freemason throughout the rest of his life.<ref>John C. van Horne, “The History and Collections of the Library Company of Philadelphia,” The Magazine Antiques, v. 170. no. 2: 58-65 (1971).</ref><ref>J.A. Leo Lemay, “Franklin, Benjamin (1706-1790),” Oxford Dictionary of National Biography, ed. H.C.G. Matthew and Brian Harrison (Oxford: OUP, 2004).[2]</ref>


Deborah Read

In 1724, while a boarder in the Read home, Franklin had courted Deborah Read before going to London at Governor Keith’s request. At that time, Miss Read’s mother was wary of allowing her daughter to wed a seventeen-year old who was on his way to London. Her own husband having recently died, Mrs. Read declined Franklin’s offer of marriage.<ref> Van Doren (1991)</ref>

While Franklin was in London, Deborah married a man named John Rodgers. This proved to be a regrettable decision. Rodgers shortly avoided his debts and prosecution by fleeing to Barbados, leaving Deborah behind. With Rodgers’ fate unknown, and bigamy illegal, Deborah was not free to remarry formally.

Franklin had his own actions to ponder. In 1730, Franklin acknowledged an illegitimate son named William, who would eventually become the last Loyalist governor of New Jersey. While the identity of William’s mother remains unknown, perhaps the responsibility of an infant child gave Franklin a reason to take up residence with Deborah Read. William was raised in the Franklin household but eventually broke with his father over the treatment of the colonies at the hands of the crown. However, he was not above using his father’s fame to enhance his own standing.

Franklin established a common-law marriage with Deborah Read on September 1, 1730. Benjamin and Deborah Franklin had two children (in addition to raising William). The first was Francis Folger Franklin, born October 1732; he died of smallpox in 1736. Sarah Franklin, nicknamed Sally, was born in 1743. She eventually married Richard Bache, had seven children, and cared for her father in his old age.

Deborah’s fear of the sea meant that she never accompanied Franklin on any of his extended trips to Europe, despite his repeated requests.


Success as author

In 1733, Franklin began to publish the famous Poor Richard’s Almanac (with content both original and borrowed) under the name Richard Saunders, on which much of his popular reputation is based. Everybody who cared to know, knew it was Benjamin Franklin but it was a different name. So when he published as Poor Richard he could say things that he didn’t want to say as Benjamin Franklin. It was as if this “other side” of Benjamin Franklin was just dying to speak his mind. “Poor Richard’s Proverbs”, adages from this almanac, such as “A penny saved is twopence dear” (often misquoted as “A penny saved is a penny earned”), “Fish and visitors stink in three days” remain common quotations in the modern world. Wisdom in folk society meant the ability to provide an apt adage for any occasion, and Franklin’s readers became well prepared. He sold about ten thousand copies per year (a circulation equal to nearly three million today).<ref> Van Doren (1991)</ref>

In 1758, the year in which he ceased writing for the Almanac, he printed Father Abraham’s Sermon. Franklin’s autobiography, published after his death, has become one of the classics of the genre.


Inventions and scientific inquiries

Franklin was a prodigious inventor. Among his many creations were the lightning rod, the glass armonica, the Franklin stove, bifocal glasses, and the flexible urinary catheter. Franklin never patented his inventions; in his autobiography he wrote, “[A]s we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.”<ref></ref>

As deputy postmaster Franklin became interested in the North Atlantic Ocean circulation patterns that carried mail ships. Franklin worked with Timothy Folger, his cousin and experienced Nantucket whaler captain, and other experienced ship captains, learning enough to chart the Gulf Stream, giving it the name by which it’s still known today. It took many years for British sea captains to follow Franklin’s advice on navigating the current, but once they did, they were able to gain two weeks in sailing time.<ref>Frontiers, published by the Academy of Natural Sciences, April, 1939</ref><ref>oceanexplorer.noaa.gov - 1785: Benjamin Franklin’s ‘Sundry Maritime Observations’</ref>

In 1743, Franklin founded the American Philosophical Society to help scientific men discuss their discoveries. He began the electrical research that, along with other scientific inquiries, would occupy him for the rest of his life, in between bouts of politics and moneymaking.<ref> Van Doren (1991)</ref>

In 1748, he retired from printing and went into other businesses. He created a partnership with his foreman, David Hall, which provided Franklin with half of the shop’s profits for 18 years. This lucrative business arrangement provided leisure time for study, and in a few years he had made discoveries that gave him a reputation with the educated throughout Europe and especially in France.

These include his investigations of electricity. Franklin proposed that “vitreous” and “resinous” electricity were not different types of “electrical fluid” (as electricity was called then), but the same electrical fluid under different pressures. He was the first to label them as positive and negative respectively,<ref>http://scienceworld.wolfram.com/biography/FranklinBenjamin.html</ref> and he was the first to discover the principle of conservation of charge.<ref>[3]</ref> In 1750, he published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. On May 10, 1752, Thomas-François Dalibard of France conducted Franklin’s experiment (using a 40-foot-tall iron rod instead of a kite) and extracted electrical sparks from a cloud. On June 15, Franklin may have possibly conducted his famous kite experiment in Philadelphia and also successfully extracted sparks from a cloud, although there are theories that suggest he never performed the experiment . Franklin’s experiment was not written up until Joseph Priestley’s 1767 History and Present Status of Electricity; the evidence shows that Franklin was insulated (not in a conducting path, since he would have been in danger of electrocution in the event of a lightning strike). (Others, such as Prof. Georg Wilhelm Richmann of St. Petersburg, Russia, were electrocuted during the months following Franklin’s experiment.) In his writings, Franklin indicates that he was aware of the dangers and offered alternative ways to demonstrate that lightning was electrical, as shown by his use of the concept of electrical ground. If Franklin did perform this experiment, he did not do it in the way that is often described, flying the kite and waiting to be struck by lightning, (as it would have been dramatic but fatal<ref>http://www.mos.org/sln/toe/kite.html</ref>). Instead he used the kite to collect some electric charge from a storm cloud, which implied that lightning was electrical.

On October 19 in a letter to England explaining directions for repeating the experiment, Franklin wrote:

“When rain has wet the kite twine so that it can conduct the electric fire freely, you will find it streams out plentifully from the key at the approach of your knuckle, and with this key a phial, or Leiden jar, maybe charged: and from electric fire thus obtained spirits may be kindled, and all other electric experiments [may be] performed which are usually done by the help of a rubber glass globe or tube; and therefore the sameness of the electrical matter with that of lightening completely demonstrated.”<ref> Wolf, A., History of Science, Technology, and Philosophy in the Eighteenth Century (New York, 1939) p.232</ref>

Franklin’s electrical experiments led to his invention of the lightning rod. He noted that conductors with a sharp rather than a smooth point were capable of discharging silently, and at a far greater distance. He surmised that this knowledge could be of use in protecting buildings from lightning, by attaching “upright Rods of Iron, made sharp as a Needle and gilt to prevent Rusting, and from the Foot of those Rods a Wire down the outside of the Building into the Ground;…Would not these pointed Rods probably draw the Electrical Fire silently out of a Cloud before it came nigh enough to strike, and thereby secure us from that most sudden and terrible Mischief!” Following a series of experiments on Franklin’s own house, lightning rods were installed on the Academy of Philadelphia (later the University of Pennsylvania) and the Pennsylvania State House (later Independence Hall) in 1752.<ref>http://www.physicstoday.org/vol-59/iss-1/p42.html</ref>

In recognition of his work with electricity, Franklin received the Royal Society’s Copley Medal in 1753, and in 1756 he became one of the few eighteenth century Americans to be elected as a Fellow of the Society. The cgs unit of electric charge has been named after him: one franklin (Fr) is equal to one statcoulomb.

On October 21, 1743, according to popular myth, a storm moving from the southwest denied Franklin the opportunity of witnessing a lunar eclipse. Franklin was said to have noted that the prevailing winds were actually from the northeast, contrary to what he had expected. In correspondence with his brother, Franklin learned that the same storm had not reached Boston until after the eclipse, despite the fact that Boston is to the northeast of Philadelphia. He deduced that storms do not always travel in the direction of the prevailing wind, a concept which would have great influence in meteorology.<ref>http://www.islandnet.com/~see/weather/almanac/arc2003/alm03oct.htm</ref>

Franklin noted a principle of refrigeration by observing that on a very hot day, he stayed cooler in a wet shirt in a breeze than he did in a dry one. To understand this phenomenon more clearly Franklin conducted experiments. On one warm day in Cambridge, England, in 1758, Franklin and fellow scientist John Hadley experimented by continually wetting the ball of a mercury thermometer with ether and using bellows to evaporate the ether. With each subsequent evaporation, the thermometer read a lower temperature, eventually reaching 7 °F (-14 °C). Another thermometer showed the room temperature to be constant at 65 °F (18 °C). In his letter “Cooling by Evaporation”, Franklin noted that “one may see the possibility of freezing a man to death on a warm summer’s day.”


Musical endeavors

Franklin is known to have played the violin, the harp, and the guitar. He also composed music, notably a string quartet in early classical style, and invented a much-improved version of the glass harmonica, in which each glass was made to rotate on its own, with the player’s fingers held steady, instead of the other way around; this version soon found its way to Europe.<ref>http://www.finkenbeiner.com/gh.html</ref>


Public life

In 1736, Franklin created the Union Fire Company, the first volunteer firefighting company in America. In the same year he printed a new currency for New Jersey based on innovative anti-counterfeiting techniques which he had devised.

As he matured, Franklin began to concern himself more with public affairs. In 1743, he set forth a scheme for The Academy and College of Philadelphia. He was appointed president of the academy in November 13, 1749, and it opened on August 13, 1751. At its first commencement, on May 17, 1757, seven men graduated; six with a Bachelor of Arts and one as Master of Arts. It was later merged with the University of the State of Pennsylvania to become the University of Pennsylvania.

In 1753, both Harvard and Yale awarded him honorary degrees [4].

In 1751, Franklin and Dr. Thomas Bond obtained a charter from the Pennsylvania legislature to establish a hospital. Pennsylvania Hospital was the first hospital in what was to become the United States of America.

Franklin became involved in Philadelphia politics and progressed rapidly. In October 1748 he was selected as a councilman, in June 1749 he became a Justice of the Peace for Philadelphia, and in 1751 he was elected to the Pennsylvania Assembly. On August 10, 1753, Franklin was appointed joint deputy postmaster-general of North America. His most notable service in domestic politics was his reform of the postal system, but his fame as a statesman rests chiefly on his subsequent diplomatic services in connection with the relations of the colonies with Great Britain, and later with France.<ref> Van Doren (1991)</ref>

In 1754, he headed the Pennsylvania delegation to the Albany Congress. This meeting of several colonies had been requested by the Board of Trade in England to improve relations with the Indians and defense against the French. Franklin proposed a broad Plan of Union for the colonies. While the plan was not adopted, elements of it found their way into the Articles of Confederation and the Constitution.

In 1757, he was sent to England by the Pennsylvania Assembly as a colonial agent to protest against the political influence of the Penn family, the proprietors of the colony. For five years he remained there, striving to end the proprietors’ prerogative to overturn legislation from the elected Assembly, and their exemption from paying taxes on their land. His lack of influential allies in Whitehall led to the failure of this mission. In 1759, the University of St Andrews awarded him an Honorary Doctor of Laws degree. In 1762, Oxford University awarded Franklin an honorary doctorate for his scientific accomplishments and from then on he went by “Doctor Franklin.” He also managed to secure a post for his illegitimate son, William Franklin, as Colonial Governor of New Jersey.<ref> Van Doren (1991)</ref>

During his stay in London, Franklin became involved in radical politics. He was a member of the Club of Honest Whigs, alongside thinkers such as Richard Price.

In 1756, Franklin became a member of the Society for the Encouragement of Arts, Manufactures & Commerce (now Royal Society of Arts or RSA, which had been founded in 1754), whose early meetings took place in coffee shops in London’s Covent Garden district, close to Franklin’s main residence in Craven Street (the only one of his residences to survive and which opened to the public as the Benjamin Franklin House museum on January 17 2006). After his return to America, Franklin became the Society’s Corresponding Member and remained closely connected with the Society. The RSA instituted a Benjamin Franklin Medal in 1956 to commemorate the 250th anniversary of Franklin’s birth and the 200th anniversary of his membership of the RSA.

During his stays at Craven Street in London between 1757 and 1775, Franklin developed a close friendship with his landlady Margaret Stevenson and her circle of friends and relations, in particular her daughter Mary, who was more often known as Polly.

In 1759, he was to visit Edinburgh with his son, and he recalled his conversations there as “the densest happiness of my life.”<ref>Buchan, Crowded with Genius, p.2</ref>

He also joined the influential Birmingham based Lunar Society who he regularly corresponded with and visited in Birmingham in the West Midlands, on occasion.


Coming of Revolution

In 1763, soon after Franklin returned to Pennsylvania, the western frontier was engulfed in a bitter war known as Pontiac’s Rebellion. The Paxton Boys, a group of settlers convinced that the Pennsylvania government was not doing enough to protect them from American Indian raids, murdered a group of peaceful Susquehannock Indians and then marched on Philadelphia. Franklin helped to organize the local miltia in order to defend the capital against the mob, and then met with the Paxton leaders and persuaded them to disperse. Franklin wrote a scathing attack against the racial prejudice of the Paxton Boys. “If an Indian injures me”, he asked, “does it follow that I may revenge that Injury on all Indians?”<ref>Franklin, “A Narrative of the Late Massacres…”</ref>

Many of the Paxton Boys’ supporters were Scotch-Irish Presbyterians and German Reformed or Lutherans from rural western Pennsylvania, leading to claims that Franklin was biased in favor of the urban Quaker elite of the East. Because of these accusations, and other attacks on his character, Franklin lost his seat in the 1764 Assembly elections. This defeat, however, allowed him the opportunity to return to London, where he sealed his reputation as a pro-American radical.<ref>Isaacson (2003).</ref>

In 1764, Franklin was dispatched to England as an agent for the colony, this time to petition King George III to establish central British control of Pennsylvania, away from its hereditary “proprietors”. During this visit he also became colonial agent for Georgia, New Jersey and Massachusetts. In London, he actively opposed the proposed Stamp Act, despite accusations by opponents in America that he had been complicit in its creation. His principled opposition to the Stamp Act, and later to the Townshend Acts of 1767, led to the end of his dream of a career in the British Government and his alliance with proponents of colonial independence. It also led to an irreconcilable break with his son William, who remained loyal to the British.<ref>Isaacson (2003)</ref>

In September 1767, Franklin visited Paris with his usual traveling partner, Sir John Pringle. News of his electrical discoveries was widespread in France. His reputation meant that he was introduced to many influential scientists and politicians, and also to King Louis XV.<ref>Isaacson (2003)</ref>

While living in London in 1768, he developed a phonetic alphabet in A Scheme for a new Alphabet and a Reformed Mode of Spelling. This reformed alphabet discarded six letters Franklin regarded as redundant (c, j, q, w, x and y), and substituted six new letters for sounds he felt lacked letters of their own; however, his new alphabet never caught on and he eventually lost interest. [5]

In 1771, Franklin traveled extensively around the British Isles staying with, among others, Joseph Priestley and David Hume. In Dublin, Franklin was invited to sit with the members of the Irish Parliament rather than in the gallery. He was the first American to be given this honor.[6] While touring Ireland he was astounded and moved by the level of poverty he saw there. Ireland was subject to the trade regulations and laws of England, which affected the Irish economy, and Franklin feared that America could suffer the same plight if Britain’s exploitation of the colonies continued.[7]

In 1773, Franklin published two of his most celebrated pro-American satirical essays: Rules by Which a Great Empire May Be Reduced to a Small One, and An Edict by the King of Prussia.[8] He also published an Abridgment of the Book of Common Prayer, anonymously with Francis Dashwood. Among the unusual features of this work is a funeral service reduced to six minutes in length, “to preserve the health and lives of the living”.<ref>Isaacson (2003)</ref>


Hutchinson Letters

Franklin obtained some private letters from Massachusetts governor Thomas Hutchinson and lieutenant governor Andrew Oliver which proved they were encouraging London to crack down on the rights of the Bostonians. Franklin sent them to America where they escalated the tensions. Franklin now appeared to the British as the fomenter of serious trouble. Hopes for a peaceful solution ended as he was systematically ridiculed and humiliated by the Privy Council. He left London in March 1775.<ref>Isaacson (2003)</ref>


Declaration of Independence

By the time Franklin arrived in Philadelphia on May 5, the American Revolution had begun with fighting at Lexington and Concord. The New England militia had trapped the main British army in Boston. The Revolutionary War had begun. The Pennsylvania Assembly unanimously chose Franklin as their delegate to the Second Continental Congress. In 1776, he was a member of the Committee of Five that drafted the Declaration of Independence and made several small changes to Thomas Jefferson’s draft.<ref>Isaacson (2003)</ref>

At the signing, he is quoted as having stated: “We must all hang together, or assuredly we shall all hang separately.”


Ambassador to France: 1776-1785

In December 1776, he was dispatched to France as commissioner for the United States. He lived in a home in the Parisian suburb of Passy, donated by Jacques-Donatien Le Ray de Chaumont who helped the United States. Franklin remained in France until 1785, and was such a favorite of French society that it became fashionable for wealthy French families to decorate their parlors with a painting of him. He was highly flirtatious in the French manner (but did not have any actual affairs). He conducted the affairs of his country towards the French nation with great success, which included securing a critical military alliance in 1778 and negotiating the Treaty of Paris (1783). During his stay in France, Benjamin Franklin as a freemason was Grand Master of the Lodge Les Neuf Sœurs from 1779 until 1781.


Constitutional Convention

When he finally returned home in 1785, he received a place only second to that of George Washington as the champion of American independence. Le Ray honored him with a commissioned portrait painted by Joseph Duplessis that now hangs in the National Portrait Gallery of the Smithsonian Institution in Washington, DC.

After his return from France, Franklin became an abolitionist, freeing both of his slaves. He eventually became president of The Society for the Relief of Free Negroes Unlawfully Held in Bondage. [9]

In 1787, he served as a delegate to the Constitutional Convention in Philadelphia. He played an honorific role but seldom engaged in debate. He is the only Founding Father who is a signatory of all four of the major documents of the founding of the United States: the Declaration of Independence, the Treaty of Paris, the Treaty of Alliance with France, and the United States Constitution.

In 1787, a group of prominent ministers in Lancaster, Pennsylvania, proposed the foundation of a new college to be named in Franklin’s honor. Franklin donated £200 towards the development of Franklin College; which is now called Franklin and Marshall College.

Between 1771 and 1788, he finished his autobiography. While it was at first addressed to his son, it was later completed for the benefit of mankind at the request of a friend.

In his later years, as Congress was forced to deal with the issue of slavery, Franklin wrote several essays that attempted to convince his readers of the importance of the abolition of slavery and of the integration of Africans into American society. These writings included:

  • An Address to the Public from the Pennsylvania Society for Promoting the Abolition of Slavery, (1789)
  • Plan for Improving the Condition of the Free Blacks (1789), and
  • Sidi Mehemet Ibrahim on the Slave Trade (1790).

In 1790, Quakers from New York and Pennsylvania presented their petition for abolition. Their argument against slavery was backed by the Pennsylvania Abolitionist Society and its president, Benjamin Franklin.


President of Pennsylvania

Special balloting conducted 18 November 1785 unanimously elected Franklin the sixth President of the Supreme Executive Council of Pennsylvania, replacing John Dickinson. The office of President of Pennsylvania was analogous to the modern position of Governor. It is not clear why Dickinson needed to be replaced with less than two weeks remaining before the regular election. Franklin held that office for slightly over three years, longer than any other President of the Council, and served the Constitutional limit of three full terms. Shortly after his initial election he was reelected to a full term on 29 October 1785, and again in the fall of 1786 and on 31 October 1787. Officially, his term concluded on 5 November 1788, but there is some question regarding the de facto end of his term, suggesting that the aging Franklin may not have been actively involved in the day-to-day operation of the Council toward the end of his time in office.


Virtue, religion and personal beliefs

Like the other advocates of republicanism, Franklin emphasized that the new republic could survive only if the people were virtuous in the sense of attention to civic duty and rejection of corruption. Indeed all his life he had been exploring the role of civic and personal virtue, as expressed in Poor Richard’s aphorisms.

Although Franklin’s parents had intended for him to have a career in the church, Franklin became disillusioned with organized religion after discovering Deism. “I soon became a thorough Deist.”[10] He went on to attack Christian principles of free will and morality in a 1725 pamphlet, A Dissertation on Liberty and Necessity, Pleasure and Pain.[11] He consistently attacked religious dogma, arguing that morality was more dependent upon virtue and benevolent actions than on strict obedience to religious orthodoxy: “I think opinions should be judged by their influences and effects; and if a man holds none that tend to make him less virtuous or more vicious, it may be concluded that he holds none that are dangerous, which I hope is the case with me.”[12]
A few years later, Franklin repudiated his 1725 pamphlet as an embarrassing “erratum”.
In 1790, just about a month before he died, Franklin wrote the following in a letter to Ezra Stiles, president of Yale, who had asked him his views on religion…:

Like most Enlightenment intellectuals, Franklin separated virtue, morality, and faith from organized religion, although he felt that if religion in general grew weaker, morality, virtue, and society in general would also decline. Thus he wrote Thomas Paine, “If men are so wicked with religion, what would they be if without it.” According to David Morgan,<ref>David T. Morgan, “Benjamin Franklin: Champion of Generic Religion.” The Historian. 62#4 2000. pp 722+</ref> Franklin was a proponent of all religions. He prayed to “Powerful Goodness” and referred to God as the “INFINITE.” John Adams noted that Franklin was a mirror in which people saw their own religion: “The Catholics thought him almost a Catholic. The Church of England claimed him as one of them. The Presbyterians thought him half a Presbyterian, and the Friends believed him a wet Quaker.” Whatever else Benjamin Franklin was, concludes Morgan, “he was a true champion of generic religion.” Ben Frankin was noted to be “the spirit of the Enlightenment”.

Walter Isaacson argues[13] that Franklin became uncomfortable with an unenhanced version of deism and came up with his own conception of the Creator. Franklin outlined his concept of deity in 1728, in his “Articles of Belief and Acts of Religion” [14]. From this, Isaacson compares Franklin’s conception of deity to that of strict deists and orthodox Christians. Isaacson concludes that unlike most pure deists, Franklin believed that a faith in God should inform our daily actions, but that, like other deists, his faith was devoid of sectarian dogma. Isaacson also discusses Franklin’s conception that God had created beings who do interfere in wordly matters—a point that has led some commentators, most notably A. Owen Aldridge, to read Franklin as embracing some sort of polytheism, with a bevy of lesser gods overseeing various realms and planets.

On July 4, 1776, Congress appointed a committee that included Benjamin Franklin, Thomas Jefferson, and John Adams to design the Great Seal of the United States. Skousen<ref> Skousen, W. Cleon, “The Five Thousand Year Leap”, National Center for Constitutional Studies (1981), pp. 17-18. </ref> summarizes how this committee created and approved the first proposed design for the seal (which ultimately was not adopted). Each member of the committee proposed a unique design: Franklin’s proposal featured a design with the motto: “Rebellion to Tyrants is Obedience to God.” This design was to portray a scene from the Book of Exodus, complete with Moses, the Israelites, the pillar of fire, and George III depicted as Pharaoh [15].

At the Constitutional Convention in 1787, when the convention seemed headed for disaster due to a vitoral debate, the elderly Franklin displayed his conviction that was intimately involved in human affairs by requesting that each day’s session begin with prayers. Franklin recalled the days of the Revolutionary War, when the American leaders assembled in prayer daily, seeking “divine guidance” from the “Father of lights.” He then rhetorically asked, “And have we now forgotten that powerful friend? Or do we imagine that we no longer need his assistance?” [16].

Although Franklin may have financially supported one particular Presbyterian group in Philadelphia [17], it nevertheless appears that he never formally joined any particular Christian denomination or any other religion.

According to the epitaph Franklin wrote for himself at the age of 20, it is clear that he believed in a physical resurrection of the body some time after death. Whether this belief was held throughout his life is unclear.[18]

Franklin consumed a mostly vegetarian diet, and he had a number of reasons for doing so. He opposed the practice of using animals as a food source, and he believed that a diet consisting of all vegetables was healthier than a diet of meat. Franklin also wanted to save money for the purchase of books, and vegetables were cheaper than meat during the 1700s. However, Franklin occasionally ate meat or fish products and was not a perfect vegetarian. <ref>PBS.org - Benjamin Franklin - Wit and Wisdom - Self-Improvement</ref> <ref>University of Delaware - Facts and Fallacies about Benjamin Franklin</ref>


Virtue

Franklin sought to cultivate his character by a plan of thirteen virtues, which he developed at age 20 (in 1726) and continued to practice in some form for the rest of his life. His autobiography (see references below) lists his thirteen virtues as:

  1. “TEMPERANCE. Eat not to dullness; drink not to elevation.”
  2. “SILENCE. Speak not but what may benefit others or yourself; avoid trifling conversation.”
  3. “ORDER. Let all your things have their places; let each part of your business have its time.”
  4. “RESOLUTION. Resolve to perform what you ought; perform without fail what you resolve.”
  5. “FRUGALITY. Make no expense but to do good to others or yourself; i.e., waste nothing.”
  6. “INDUSTRY. Lose no time; be always employ’d in something useful; cut off all unnecessary actions.”
  7. “SINCERITY. Use no hurtful deceit; think innocently and justly, and, if you speak, speak accordingly.”
  8. “JUSTICE. Wrong none by doing injuries, or omitting the benefits that are your duty.”
  9. “MODERATION. Avoid extremes; forbear resenting injuries so much as you think they deserve.”
  10. “CLEANLINESS. Tolerate no uncleanliness in body, cloaths, or habitation.”
  11. “TRANQUILLITY. Be not disturbed at trifles, or at accidents common or unavoidable.”
  12. “CHASTITY. Rarely use venery but for health or offspring, never to dullness, weakness, or the injury of your own or another’s peace or reputation.”
  13. “HUMILITY. Imitate Jesus and Socrates.”


Death and legacy

Franklin died on April 17, 1790, at age 84. His funeral was attended by approximately 20,000 people. He was interred in Christ Church Burial Ground in Philadelphia. One of the houses he lived in on Craven Street was first marked with a blue plaqu
