Raymond Z. Gallun (rhymes with "balloon") was born in rural Wisconsin in 1910. He attended one year of college at the University of Wisconsin, then left to travel in Europe. He started writing science fiction in 1929; he attained widespread recognition with Old Faithful in 1934. Also wrote stories under the name William Callahan.
