What 10 things did Benjamin Franklin invent?

Franklin’s inventions are a catalog of practical problem-solving. Here are ten of his most notable creations, each addressing a specific need.

What is the lightning rod?

Invented in 1749, the lightning rod is a metal rod mounted on buildings to divert lightning strikes safely into the ground (USHistory.org – lightning rod explanation). Franklin’s experiments with electricity convinced him that lightning was electrical, and he designed the rod to protect fire-prone wooden structures.

What are bifocals?

Bifocals (1784) allowed Franklin to see both near and far without switching glasses. He grew tired of changing between two pairs and had his lens cut in half, combining them into one frame (Biography.com – bifocals story).

How does the Franklin stove work?

Patented in 1742, the Franklin stove (or “Pennsylvania stove”) was a cast-iron furnace that used a system of baffles to extract more heat from the same amount of fuel. It was designed to be safer and more efficient than open hearths (Franklin Institute – stove design).

What other inventions did Franklin create?

• Glass harmonica (1761) – a musical instrument using spinning glass bowls (Franklin Institute – glass harmonica).

• Odometer – attached to his carriage to measure postal routes (Britannica – odometer).

Why is Ben Franklin on the $100 bill?

Franklin’s portrait has appeared on the $100 bill since 1914 (Wikipedia – $100 bill history). He was chosen because of his immense popularity and his role as a Founding Father, not because he was a president. The U.S. Treasury reserves the $100 bill for the most recognizable figures, and Franklin’s image is one of the most widely circulated.

When did Franklin first appear on U.S. currency?

Before the $100 bill, Franklin appeared on the $50 bill (1914–1929) and even on a $1,000 note in the 19th century (Wikipedia – earlier denominations).

What other denominations featured Franklin?

Franklin’s portrait also appeared on various government bonds and stamps, but the $100 bill is his most enduring currency appearance. He is the only non-president on standard U.S. paper currency issued today (Britannica – currency fact).

Is Franklin the only non-president on U.S. paper money?

Yes, among current circulating bills, Franklin is the only non-president. Alexander Hamilton appears on the $10 bill but was Secretary of the Treasury, not a president. Franklin’s selection reflects his unique status as a national icon (Wikipedia – non-president currency).

The irony: A man who never sought the presidency became the face of the nation’s most valuable bill.

What was Benjamin Franklin’s famous quote?

Franklin’s most famous quotes come from Poor Richard’s Almanack and his letters. They mix practical wisdom with a dry wit that still resonates.

What are the most famous sayings from Poor Richard’s Almanack?

• “Early to bed and early to rise makes a man healthy, wealthy, and wise.” (Biography.com – Almanack quotes)
• “A penny saved is a penny earned.” (Franklin Institute – proverb)
• “Well done is better than well said.” (Benjamin Franklin Historical Society – moral maxims)
• “Tell me and I forget, teach me and I may remember, involve me and I learn.” (attributed, often paraphrased)

Which quote is most attributed to Franklin?

“In this world nothing can be said to be certain, except death and taxes.” That line comes from a 1789 letter to Jean-Baptiste Le Roy (Wikipedia – death and taxes).

What did Franklin say about time and money?

He wrote extensively on the value of time. “Time is money” is a paraphrase from his 1748 essay “Advice to a Young Tradesman” (Britannica – time is money).

Franklin’s aphorisms still shape everyday language, proving that a well-turned phrase can outlast empires.

Was Benjamin Franklin of Irish descent?

No, Benjamin Franklin’s ancestry is primarily English, not Irish. His father, Josiah Franklin, was born in Ecton, Northamptonshire, England, and emigrated to Boston (Wikipedia – father’s origin). His mother, Abiah Folger, was born in Boston to English parents who had emigrated from Somerset, England (Britannica – mother’s background).

Where were Franklin’s ancestors from?

Genealogical records show that Franklin’s paternal line came from the village of Ecton in Northamptonshire. The Folger family (mother’s side) was from Somerset, England. There is no verifiable evidence of Irish descent (Biography.com – ancestry detail).

Did Franklin have Irish heritage?

Despite persistent myths, Franklin never claimed Irish ancestry. The confusion may arise from his sympathy for Irish causes and his published letters supporting Irish independence, but his own bloodline is English (Wikipedia – Irish sympathies).

What was Franklin’s father’s background?

Josiah Franklin was a tallow chandler and soap maker who left England in 1682 for religious freedom. He settled in Boston and raised 17 children across two marriages. Benjamin was the 15th child and the youngest son (Britannica – father’s story).

The lesson: Even a well-documented lineage can be overridden by a good story.

Are there descendants of Benjamin Franklin alive today?

Yes, there are living descendants of Benjamin Franklin, but none carry the Franklin surname from his direct male line. Franklin had three children, and only his daughter Sarah produced grandchildren who survived to adulthood (Wikipedia – descendants).

How many children did Franklin have?

• William Franklin (illegitimate) – born around 1730; became the last royal governor of New Jersey; loyal to Britain during the Revolution (Britannica – William Franklin).
• Francis Folger Franklin – died of smallpox at age 4 (1736) (Wikipedia – Francis Franklin).
• Sarah “Sally” Franklin – married Richard Bache; had seven children, carrying on the family line (Biography.com – Sarah Franklin).

Did his descendants carry on his legacy?

William Franklin’s descendants remained in Britain, but the Bache line (from Sarah) produced many notable Americans, including a U.S. Navy officer and a philanthropist. Today, the Franklin surname is extinct in Benjamin’s direct male line, but the Bache family continues (Wikipedia – Bache descendants).

Are there living direct descendants?

Yes, through Sarah’s line, there are living descendants. The Franklin family association maintains records of these connections. However, no one carries the surname “Franklin” from Benjamin’s own bloodline (Britannica – descendant status).

The twist: Franklin’s bloodline continues, but not under his own name.

What did Benjamin Franklin say before he died?

Franklin’s final words are a matter of historical record, though accounts vary. He died on April 17, 1790, at age 84, surrounded by family (Wikipedia – death).

What were Franklin’s last recorded words?

His daughter Sally asked him to change position in bed. He reportedly replied, “A dying man can do nothing easily.” Some accounts also record him saying, “I hope I shall soon be well.” The first version is more widely cited (Biography.com – last words).

Did Franklin say anything about his legacy?

No, his final hours were marked by a lung abscess and pleurisy. He was too ill for lengthy statements. The family noted he was lucid until the end but spoke only briefly (Britannica – final illness).

How did Franklin die?

Franklin suffered from pleurisy and a lung abscess that caused respiratory failure. His health had been declining for several years, and he died peacefully at his home in Philadelphia (Wikipedia – cause of death).

Franklin’s end was as unpretentious as his beginnings, a reminder that even the greatest minds face mortality with simple words.
