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

Why this is the answer

One name answers this two-part question, because Franklin Roosevelt, often called FDR, held the presidency through both crises. He became the 32nd President in 1933, with the country deep in the Great Depression, and he served until he died in office in 1945, the year World War II ended. His answer to the Depression was the New Deal, a set of programs to create jobs and give workers benefits and financial security. Social Security, set up in 1935, came out of it. Then came the war. Japan attacked Pearl Harbor on December 7, 1941. The next day Roosevelt announced that the United States would enter World War II, and Congress voted to declare war that same day. He was elected four times and remains the longest-serving President in the country's history. In 1951 the 22nd Amendment limited a President to two elections, so that record cannot be repeated. The official answer is written "(Franklin) Roosevelt." The first name is in parentheses, so "Roosevelt" alone is accepted. Saying the full name is still a good habit, because the country has had two Presidents named Roosevelt. Theodore Roosevelt was inaugurated in 1905, decades before either crisis. Two other wrong answers come from nearby questions. Woodrow Wilson was President during World War I, from 1913 to 1921, long before the Depression. There is a quick check you can run in your head: the question names two events, and only one President was in office for both. When Roosevelt died in office in 1945, his Vice President became President, which is what the rules of succession call for. It also helps that Roosevelt's two crises sit side by side on the official list, in questions 103 through 106, so you can study the Depression, the crash, the President and Pearl Harbor as one block.
