Scientist and inventor
Franklin’s experiments demonstrated that lightning is electricity, and he introduced ideas and terminology still used in the field. Endlessly practical, he invented the lightning rod, bifocal glasses and the efficient Franklin stove — and, on principle, patented none of them, so that all could benefit.
Statesman and diplomat
Franklin signed both the Declaration of Independence and the Constitution. His greatest service to the American Revolution came in Paris, where his fame and charm secured the French alliance that proved decisive to the cause led by George Washington.
Legacy
Witty, wise and endlessly curious, Franklin became one of the most admired men of his century — embraced even by Voltaire in Paris. He remains a symbol of American ingenuity and the Enlightenment faith in reason and self-improvement.
Influence
Franklin embodied the Enlightenment ideal of the self-made, rational, public-spirited individual, and his scientific and diplomatic achievements shaped both the new United States and the study of electricity.
Legacy
One of the most beloved Founding Fathers, Franklin appears on the U.S. hundred-dollar bill and remains a symbol of American ingenuity and Enlightenment values.
Controversies
- He owned enslaved people earlier in life but later became a prominent abolitionist.
