George Washington
On the dollar bill since 1869
Washington has anchored the one-dollar Federal Reserve Note since 1869, and for good reason: he commanded the Continental Army through eight years of war, presided over the Constitutional Convention, and served as the first president of the United States from 1789 to 1797.
His portrait replaced the Salmon P. Chase version of the greenback after the Civil War, and it has stayed put ever since — the longest-running portrait on any piece of American currency.
