Franklin D. Roosevelt
Franklin Delano Roosevelt ( , ; January 30, 1882April 12, 1945), often referred to by his initials FDR, was an American politician who served as the 32nd president of the United States from 1933 until his death in 1945. A member of the Democratic Party, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century. Roosevelt directed the federal government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, which realigned American politics into the Fifth Party System and defined American liberalism throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II, which ended shortly after he died in office.
Franklin D. Roosevelt
Roosevelt was born in Hyde Park, New York, to the Roosevelt family made well known by the reputation of Theodore Roosevelt, the 26th president of the United States, as well as businessman William Henry Aspinwall. FDR graduated from Groton School and Harvard College and attended Columbia Law School but left after passing the bar exam to practice law in New York City. In 1905, he married his fifth cousin once removed, Eleanor Roosevelt. They had six children, of whom five survived into adulthood. He won election to the New York State Senate in 1910, and then served as Assistant Secretary of the Navy under President Woodrow Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic Party's 1920 national ticket, but Cox was defeated by Republican Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness, believed at the time to be polio, and his legs became permanently paralyzed. While attempting to recover from his condition, Roosevelt founded the treatment center in Warm Springs, Georgia, for people with poliomyelitis. In spite of being unable to walk unaided, Roosevelt returned to public office by winning election as Governor of New York in 1928. He served as governor from 1929 to 1933, promoting programs to combat the economic crisis besetting the United States.
