Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945), also known as FDR, was the 32nd president of the United States, serving from 1933 until his death in 1945. He is the longest-serving U.S. president, as well as the only one to have served more than two terms. His first two terms were centered on combating the Great Depression, while his third and fourth saw him shift his focus to U.S. involvement in World War II. A member of the Democratic Party, Roosevelt previously served in the New York State Senate from 1911 to 1913, the assistant secretary of the Navy under President Woodrow Wilson from 1913 to 1920, and as the 44th governor of New York from 1929 to 1932.
Born into the prominent Delano and Roosevelt families in Hyde Park, New York, Roosevelt graduated from Harvard University with a Bachelor of Arts. He entered Columbia Law School in 1904, but dropped out in 1907 after passing the New York bar examination. Roosevelt was elected to the New York State Senate from 1911 to 1913 before serving as the assistant secretary of the Navy under President Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic ticket in the 1920 presidential election, which Cox lost to Republican nominee Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness that permanently paralyzed his legs. However, he returned to the public office upon being elected governor of New York in 1928, partly through the encouragement of his wife Eleanor, and during his tenure as governor of New York, he promoted programs to combat the Great Depression. After receiving the Democratic nomination, Roosevelt defeated President Herbert Hoover in a landside victory in the 1932 presidential election.
