As of 2014, the face shown on the U.S. $100 bill belongs to Benjamin Franklin. The Federal Reserve System was formed in 1913, and it issued the first $100 bill featuring the prominent Franklin in 1914.
The $100 bill has gone through several changes over the years, with the most updated bill as of 2014 having been released in October 2013. As counterfeit technology evolves, so must currency to safeguard against fraud. Counterfeit prevention built-in the 2013 version includes an interwoven blue ribbon and a color-changing Liberty Bell. Franklin is honored on the currency for his notable contributions to American history, including helping draft the Declaration of Independence and signing the Constitution.
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.
