     Franklin D. Roosevelt was the thirty-second president of the United States. He was elected four times. He served as president longer than anyone else, from 1933 until 1945. He led the United States through the Great Depression and the Second World War. He died in office. Roosevelt got polio when he was 39 years old. Polio is a terrible disease. It killed and paralyzed many people. The disease spread quickly; there was no cure. (Today there is a vaccine.) Roosevelt did not let polio stop him. He learned to walk with leg braces and crutches. In the picture, he is standing up with the help of his son. Roosevelt was a strong president with many ideas.
