Who was president during the Great Depression and World War II?

Why this is the answer

Franklin Roosevelt, often called FDR, was President from 1933 until his death in 1945, longer than anyone else, and his years in office covered both crises. He was elected during the Great Depression and created programs to put people back to work, and he led the country into World War II after Japan attacked Pearl Harbor in December 1941. He was elected four times; the two-term limit of the 22nd Amendment came after him. The official answer is Roosevelt, with or without the first name. Memory hook: the Depression president and the World War II president are the same man.
