Who is Franklin D. Roosevelt from The Creature from Jekyll Island: A Second Look at the Federal Reserve and what is their importance?

Roosevelt was President of the United States from 1933 to 1945. He became famous for establishing what the author called socialism or the New Deal. The author claimed that the New Deal actually elongated the Great Depression by thwarting the natural laws of economics in capitalism. According to the author, the only way the US broke out of the depression was the advent of World War II and the resulting mass industrialization.
