Kurt Vonnegut, Jr. was an American writer. His works such as Cat's Cradle, Slaughterhouse-Five, and Breakfast of Champions blend satire, gallows humor, and science fiction. As a citizen he was a lifelong supporter of the American Civil Liberties Union and a critical pacifist intellectual. He was known for his humanist beliefs and was honorary president of the American Humanist Association.
The New York Times headline at the time of Vonnegut's passing called Vonnegut "the counterculture's novelist."
