http://en.wikipedia.org/wiki/Kurt_Vonnegut
Vonnegut was a humanist; he served as Honorary President of the American Humanist Association, having replaced Isaac Asimov in what Vonnegut called "that totally functionless capacity". He was deeply influenced by early socialist labor leaders, especially Indiana natives Powers Hapgood and Eugene V. Debs, and he frequently quotes them in his work. He named characters after both Debs (Eugene Debs Hartke in Hocus Pocus) and Russian Communist leader Leon Trotsky (Leon Trotsky Trout in Galapagos). He was a lifetime member of the American Civil Liberties Union, and was featured in a print advertisement for them.

He would joke now that he has gone to join his father in heaven.
