Harry S. Truman: "Music" Is His Middle Name?
A few composers are usually referred to by one or more of their initials, such as J.S. Bach or his son, C.P.E. Bach. In these cases, the initials stand for actual names.
It’s interesting that in the case of President Harry S. Truman, the “S” actually stood only for itself as an initial with no name represented. His musical connection? He enjoyed playing the piano.
