An earlier portrait of Benjamin Franklin by Joseph-Siffred Duplessis ran on all $100 bills from 1929 until 1993. In 1996 a portrait of an older Benjamin Franklin by the same painter was used.
Benjamin Franklin was a printer by trade and published many works, including "Poor Richard's Almanac." In 1743, he began concentrating on science and experiments, inventing a heat-efficient stove, swim fins and bifocals. The most notable of his contributions to science is his famous experiment with lightning and kites, which confirmed the nature of electricity.Learn more about Coins & Currency
