Harry S. Truman was the last President of the United States elected with only a high school diploma. Harry S. Truman was elected Nov 5, 1948, after most Americans believed Thomas Dewey had defeated him.
Harry S Truman's daughter was Mary Margaret Truman. She was born on February 17, 1924 and she passed away on January 29, 2008 at age 83 from an infection. He was an author of several murder-mystery books.
Truman middle name has been the subject of much debate. I believe the current version is that he was given only the initial , S., as a compromise to honor both of his grandfathers both of whom had "S" as an initial.
