Franklin D. Roosevelt
Franklin D. Roosevelt was the 32nd President of the United States, serving an unprecedented four terms and leading the country through the Great Depression and most of World War II.
Roosevelt took office in 1933 amid the depths of the Great Depression and launched a sweeping set of programs known as the New Deal, creating jobs, financial regulations, and social safety net programs including Social Security.
Despite contracting polio in 1921, which left him unable to walk without assistance, Roosevelt largely kept his condition private from the public during his political career.
He led the United States through most of World War II, working closely with Allied leaders, before dying in office in April 1945, just weeks before Germany's surrender. He remains the only US president to serve more than two terms.
