Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945) , often referred to by his initials FDR, was the thirty-second President of the United States. Elected to four terms in office, he served from 1933 to 1945 and is the only U.S. president to have served more than two terms. He was a central figure of the 20th century during a time of worldwide economic crisis and world war.
During the Great Depression of the 1930s, Roosevelt created the New Deal to provide relief for the unemployed, recovery of the economy, and reform of the economic and banking systems.[1] Although recovery of the economy was incomplete until almost 1940, the programs he initiated such as the Federal Deposit Insurance Corporation (FDIC), Tennessee Valley Authority (TVA), and the United States Securities and Exchange Commission (SEC) continue to have instrumental roles in the nation's commerce. One of his most important legacies is the Social Security system.
