On January 20, 1945, Franklin Delano Roosevelt was the first and only president to be inaugurated for a 4th term in office. Five years earlier, with World War II raging in Europe and the Pacific, the President had agreed to run for an unprecedented third term. In '44 -- the war not yet won -- Americans reelected their leader for yet another term in office. He died three months after the inauguration. Here he's shown with his Chelseas in the 1930s.
