11 Surprising Facts About Benjamin Franklin

Posted on

Benjamin Franklin stands as one of the most consequential figures in American Revolution history — a self-taught printer, diplomat, inventor, and reluctant revolutionary whose life intersected with the most turbulent decades of colonial America. Yet popular memory often flattens him into a caricature of kite-flying and aphorisms, obscuring a far stranger and more fascinating historical record. From his legendary interrogation before Parliament defending Native American treaty diplomacy, to his late-life abolitionism and bitterly fractured relationship with his Loyalist son William, Franklin’s biography reveals a man whose intellectual curiosity and political judgment were forged in provincial Boston, refined in Philadelphia, and tested in the courts of London and Paris. This article examines eleven historically documented aspects of Franklin’s life — each grounded in verifiable primary sources and scholarly consensus — that illuminate his role in shaping the nation and his complicated engagement with the Indigenous nations whose sovereignty framed the era’s diplomatic landscape.

A Self-Taught Mind Outside the Classroom

The man considered the most brilliant American of his age rarely saw the inside of a classroom. Franklin spent just two years attending Boston Latin School and a private academy before joining the family candle and soap-making business. By age twelve, he was serving as an indentured apprentice at a printing shop owned by his brother, James. Young Benjamin compensated for his lack of formal schooling by spending what little money he earned on books, often going without food to afford new volumes. He also honed his composition skills by reading essays and periodicals and then rewriting them from memory — a disciplined method of self-instruction that would later inform his writing style in the Pennsylvania Gazette and Poor Richard’s Almanack.

Despite being almost entirely self-taught, Franklin later helped found the school that became the University of Pennsylvania and received honorary degrees from Harvard, Yale, the College of William and Mary, the University of St. Andrews, and Oxford. This trajectory — from indentured apprentice to internationally recognized scholar — reflects an era when colonial intellectual life was still emerging and formal credentials carried less weight than demonstrable achievement.

The Silence Dogood Letters and Philadelphia

After his brother James founded a weekly newspaper called the New England Courant in the 1720s, a sixteen-year-old Franklin began secretly submitting essays and commentary as “Silence Dogood,” a fictitious widow who offered homespun musings on everything from fashion and marriage to women’s rights and religion. The letters were hugely popular, and Mrs. Dogood soon received several marriage proposals from eligible bachelors in Boston. Franklin penned fourteen Dogood essays before unmasking himself as their author, much to his jealous brother’s chagrin.

Sick of the toil and beatings he endured as James’s apprentice, the teenaged sensation fled Boston the following year and settled in Philadelphia — the city that would remain his adopted home for the rest of his life. Arriving in 1723 practically penniless, he became enormously wealthy over the next two decades as a print shop owner, land speculator, and publisher of the popular Poor Richard’s Almanack. By 1748, the forty-two-year-old was rich enough to retire and spend his remaining forty-two years studying science and devising inventions such as the lightning rod, bifocal glasses, and his more efficient heating stove — the Franklin Stove.

Public Service Without Elected Office

Despite never running for elected office, Franklin served as a delegate to the Continental Congress and the Constitutional Convention, diplomat and ambassador to France and Sweden, the first postmaster general, and president of the Supreme Executive Council of Pennsylvania. His diplomatic experience brought him into direct contact with the treaty negotiations that reshaped North America, particularly during the 1763 negotiations that followed the French and Indian War — a conflict in which Native nations were both combatants and diplomatic parties whose territorial claims European powers were forced to acknowledge formally.

The Glass Armonica: A Musical Invention

Among Franklin’s more unusual inventions is his “glass armonica,” an instrument designed to replicate the otherworldly sound that a wet finger makes when rubbed along the rim of a glass. He made his first prototype in 1761 by having a London glassmaker build him thirty-seven glass orbs of different sizes and pitches, which he mounted on a spindle controlled by a foot pedal. To play the instrument, the user would wet their fingers, rotate the apparatus, and touch the glass pieces to create individual tones or melodies.

The armonica amassed a considerable following during the eighteenth and early nineteenth centuries. Thousands were manufactured, and Mozart, Beethoven, and Strauss all composed music for it. Franklin would later write that “Of all my inventions, the glass armonica has given me the greatest personal satisfaction.”

Franklin’s Defense of Native American Treaties in Parliament

One of Franklin’s most consequential yet underappreciated contributions occurred in January 1766, when he appeared before the House of Commons to testify regarding the Stamp Act. During this famous interrogation, Franklin famously stated that the colonies had never been motivated to seek independence by external pressure, and he cited the example of the Crown’s land policies — including the Proclamation of 1763, which sought to reserve territory west of the Appalachian Mountains for Native nations — as a source of colonial grievance.

Franklin’s testimony drew on his practical experience negotiating with Native nations, particularly his participation in the 1753 Carlisle Treaty with the Ohio Country tribes and his drafting of the Albany Plan of Union in 1754, which drew inspiration from the political structures of the Haudenosaunee Confederacy. His firsthand knowledge of Native diplomacy shaped his understanding of the empire as a complex web of negotiated sovereignties rather than a simple hierarchy of ruler and subject.

The Albany Plan and Haudenosaunee Influence

Franklin’s 1754 Albany Plan of Union — a proposal for a unified colonial government — was crafted at a congress where delegates met with Haudenosaunee (Iroquois) representatives. Scholars have long debated the extent to which Franklin drew directly from the Confederacy’s political institutions, but his own writings referenced the “Six Nations” as a model of cooperative governance. Though the Plan was rejected by both the Crown and the colonies, it laid intellectual groundwork for the later Articles of Confederation and the federal structure of the United States.

Franklin’s Slow Conversion to Independence

Franklin was among the last of the Founding Fathers to come out in favor of full separation from Britain. Having lived in London for several years and held royal appointments, he instead pushed for peaceful compromise and the preservation of the empire, once writing that “every encroachment on rights is not worth a rebellion.” When the Boston Tea Party took place in 1773, he dubbed it an “act of violent injustice on our part” and insisted that the East India Company should be compensated for its losses.

Franklin had soured on the monarchy by the time he returned to the United States for the Second Continental Congress in 1775, but his past support for King George III earned him the suspicion of many fellow patriots. Before he publicly announced his support for American independence, a few even suspected he might be a British spy.

The Phonetic Alphabet Scheme

While living in London in 1768, Franklin embarked on a project “to give the alphabet a more natural order.” Annoyed by the many inconsistencies in English spelling, he devised his own phonetic system that dropped the redundant consonants C, J, Q, W, X, and Y and added six new letters, each designed to represent its own specific vocal sound. Franklin unveiled his “Scheme for a new Alphabet and a Reformed Mode of Spelling” in an essay published in 1779, but later scrapped the project after it failed to arouse public interest.

The Bitter Rift with His Son William

Along with the two children he had with his wife, Deborah Read, Franklin also fathered an illegitimate son named William around 1730. The two were once close friends and partners — William helped Franklin with his famous kite experiment — but they later had a major falling out over the American Revolution. While Franklin joined in calling for independence from the mother country, William remained a staunch Loyalist who branded the patriots “intemperate zealots” and refused to resign his post as the royal governor of New Jersey.

William spent two years in a colonial prison for opposing the revolution and later became a leader in a Loyalist group before moving to England at the end of the war. The elder Franklin never forgave his son for “taking up arms against me.” He all but cut William out of his will, arguing, “the part he acted against me in the late war…will account for my leaving him no more of an estate he endeavored to deprive me of.”

Franklin in Paris and His Famous Fur Hat

In 1776, the Continental Congress sent Franklin to France to seek military aid for the revolution. The seventy-year-old was already world-renowned for his lightning experiments — the French even called their electrical experimenters “Franklinistes” — but his fame soared to new heights after his arrival in Paris. Franklin capitalized on the French conception of Americans as rustic frontiersmen by dressing plainly and wearing a fur hat, which soon became his trademark and appeared in countless French portraits and medallions.

Women even imitated the cap with oversized wigs in a style called “coiffure à la Franklin.” When Franklin later traded the fur cap for a white hat during the signing of the 1778 treaty between France and the United States, white-colored headgear instantly became a fashion trend among the men of Paris.

Franklin’s Late-Life Abolitionism

Franklin owned at least two slaves during his life, both of whom worked as household servants, but in his old age he came to view slavery as a vile institution that ran counter to the principles of the American Revolution. He took over as president of a Pennsylvania abolitionist society in 1787, and in 1790 he presented a petition to Congress urging it to grant liberty “to those unhappy men who alone in this land of freedom are degraded into perpetual bondage.” While the petition was ignored, Franklin kept up the fight until his death a few months later. He even included a provision in his will that required his daughter and son-in-law to free their enslaved person to receive their inheritance.

The 200-Year Trust Fund to Boston and Philadelphia

When he died in April 1790, Franklin willed 2,000 pounds sterling to his birthplace of Boston and his adopted home of Philadelphia. The largesse came with an unusual caveat: for its first hundred years, the money was placed in a trust and only used to provide loans to local tradesmen. A portion could then be spent, but the rest remained off-limits for another hundred years. Boston and Philadelphia followed Franklin’s wishes, and by 1990 their funds were worth approximately $4.5 million and $2 million, respectively. The two cities have since used the windfall to help finance the Franklin Institute in Philadelphia and the Benjamin Franklin Institute of Technology in Boston. Philadelphia also directed some funds toward scholarships for students attending trade schools.

Franklin the Passionate Swimmer

Franklin had a lifelong love of swimming that began during his childhood in Boston. One of his first inventions was a pair of wooden hand paddles he used to propel himself through the Charles River, and he wrote of once using a kite to skim across a pond. While living in England in the 1760s, he displayed such an impressive array of swimming strokes during a dip in the Thames that a friend offered to help him open his own swimming school. Franklin declined, but remained a proponent of swimming instruction for the rest of his life, once writing, “every parent would be glad to have their children skilled in swimming.” His aquatic exploits have earned him an honorary induction into the International Swimming Hall of Fame.

Historical Context & Key Cultural Takeaways

Franklin’s long career unfolded precisely during the decades when the relationship between the British Crown and Native nations was being fundamentally renegotiated. His 1766 testimony before Parliament, his drafting of the Albany Plan, and his involvement in the 1763 negotiations all reflected a colonial worldview in which Indigenous sovereignty was a reality to be managed rather than dismissed. Although Franklin personally advocated for colonial expansion, his recognition that Native nations were political entities with legitimate territorial claims distinguished him from many contemporaries who treated Indigenous peoples as obstacles to settlement.

His late-life abolitionism similarly placed him at odds with the prevailing economic systems of his day, and his willingness to publicly fund a petition calling for emancipation — despite owning enslaved people himself — illustrates how Revolutionary principles of liberty were increasingly being applied to their fullest logical extent. These two strands of Franklin’s career — engagement with Native diplomacy and evolving opposition to slavery — reveal a thinker whose conclusions were not always consistent with his conduct, but whose willingness to follow an argument to its end shaped the intellectual trajectory of the early republic.

Frequently Asked Questions

What role did Benjamin Franklin play in Native American treaty negotiations?

Franklin participated in several treaty negotiations with Native nations, most notably the 1753 Carlisle Treaty with Ohio Country tribes and his 1754 Albany Congress work with the Haudenosaunee Confederacy. His 1766 testimony before Parliament also referenced Native diplomacy and the Proclamation of 1763 as key contexts for understanding colonial grievances.

How did Franklin’s Albany Plan relate to Indigenous political structures?

The Albany Plan of Union — Franklin’s 1754 proposal for a unified colonial government — was devised at a congress where colonial delegates met with Haudenosaunee representatives. Franklin explicitly cited the Six Nations as a model of cooperative governance, though historians continue to debate the precise extent of the influence.

Did Benjamin Franklin own enslaved people?

Yes, Franklin owned at least two enslaved people during his lifetime, both of whom worked as household servants. However, in his later years he became an abolitionist, serving as president of the Pennsylvania Abolition Society from 1787 until his death in 1790.

Where are Franklin’s papers and artifacts preserved today?

The majority of Franklin’s surviving papers are held by the American Philosophical Society in Philadelphia, the Library of Congress, and Yale University. Artifacts associated with his scientific work are preserved at the Franklin Institute in Philadelphia and the Smithsonian Institution in Washington, D.C.

What was the Proclamation of 1763 and why did it matter?

Issued by King George III in October 1763 following the French and Indian War, the Proclamation reserved territory west of the Appalachian Mountains for Native nations and sought to regulate colonial settlement. It was deeply resented by colonists hoping to expand westward and became a contributing factor in the tensions that led to the American Revolution.

Concluding Synthesis: The Legacy of a Complicated Founder

Benjamin Franklin’s life resists easy categorization. He was a self-taught printer who corresponded with kings; a colonial loyalist who became an architect of independence; an enslaver who petitioned Congress for emancipation. His engagement with Native nations — through treaty negotiations, his Albany Plan, and his parliamentary testimony — reflected a colonial era in which Indigenous sovereignty was a structural feature of North American politics that no serious statesman could ignore. Understanding Franklin requires acknowledging both his genuine intellectual curiosity and the historical context that constrained his perspective. The institutions he helped found — the University of Pennsylvania, the American Philosophical Society, the U.S. postal system — remain part of the living republic, while the treaty negotiations and land policy disputes in which he participated continue to shape debates over the historical legacy of federal Indian policy and tribal sovereignty today.

Tribal & Historical Heritage Reference

The Haudenosaunee Confederacy (Iroquois) and Ohio Country nations engaged in diplomatic negotiations with colonial delegates including Franklin. Primary documents relating to these treaties — including the Albany Plan of Union and the 1763 Proclamation — are preserved in the Library of Congress, the American Philosophical Society, and the National Archives. Research institutions specializing in Native American history include the Newberry Library (Chicago) and the Smithsonian National Museum of the American Indian (Washington, D.C.).
