Who was the last vice president of Franklin Delano Roosevelt?

Harry S. Truman had been vice president for 82 days when President Roosevelt died on April 12, 1945. That afternoon, Truman presided over the Senate as usual. He had just adjourned the session for the day and was preparing to have a drink in House Speaker Sam Rayburn's office when he received an urgent message to go immediately to the White House. Truman assumed that President Roosevelt wanted to meet with him, but Eleanor Roosevelt informed him that her husband had died after suffering a massive cerebral hemorrhage. Truman's first concern was for Mrs. Roosevelt. He asked if there was anything he could do for her, to which she replied, "Is there anything we can do for you? You are the one in trouble now!"
