Earl Kemp (born November 24, 1929) is an American publisher, science fiction editor, critic, and fan who won a Hugo Award for Best Fanzine in 1961 for Who Killed Science Fiction, a collection of questions and answers with top writers in the field. Kemp also helped found Advent:Publishers, a small publishing house focused on science fiction criticism, history, and bibliography, and served as chairman of the 20th World Science Fiction Convention. During the 1960s and '70s, Kemp was also involved in publishing a number of erotic paperbacks, including an illustrated edition of the Presidential Report of the Commission on Obscenity and Pornography. This publication led to Kemp being sentenced to one year in prison for "conspiracy to mail obscene material," but he served only the federal minimum of three months and one day.
Kemp was born in Arkansas in 1929 and later moved to Chicago, where he worked as a graphics artist.
Before Kemp left Arkansas, he discovered pulp fiction. As Kemp once wrote, "There were a number of magazines that struck my fancy for different reasons, among them were titles like Planet Stories, Weird Tales, Spicy Mystery Stories, etc. It was probably my emerging pubescence tilting me toward the spicy parts, but I had always been easy to tilt."
In 1952, Kemp attended his first World Science Fiction Convention. As he later said, "It was like walking into a world I had been seeking for a very long time. I felt, instantly, that I was at home at last and among my kind of people."
In 1956 Kemp and other members of the University of Chicago Science Fiction Club founded Advent:Publishers, which publishes science fiction criticism, history, and bibliography. One of their first books was In Search of Wonder, a hardcover collection of the book reviews of Damon Knight. Critics have said the book created the "foundation for all subsequent SF criticism."
