The 32nd president of the United States was Franklin D. Roosevelt. He was actually the only president in US history to serve three full terms. He died on his fourth term, though. He served from March 4, 1933-April 12, 1945, until he died. He would have been the first president of the US to serve four full terms, if he did not die. Anyways, I hope this helped answer your question for you. Enjoy your day, and take care.
