Margaret Truman Daniel, the only child of President Harry Truman, has passed away at the age of 83 in a Chicago assisted-care facility. A mystery novelist, Truman is best remembered for an incident regarding her former singing career. After critic Paul Hume panned her performance, Harry sent him a letter threatening "you'll need a new nose, a lot of beefsteak for black eyes, and perhaps a supporter down below. You are a guttersnipe!" Give those critics hell, Harry!
