"Margaret Truman Daniel, 83, President Harry Truman's only child, a mystery novelist whose early efforts as a singer famously led her father to threaten an unkind critic with a punch to the nose, died on Tuesday in Chicago after a brief illness, according to a spokesman for the Harry S. Truman Library and Museum."
Perhaps she is most famous for an incident in 1950: "A Washington critic panned one of her performances, prompting the president to write a letter on White House stationery that read in part: "Some day I hope to meet you. When that happens you'll need a new nose, a lot of beefsteak for black eyes, and perhaps a supporter below.""
