William Tenn is the pen name of London-born Philip Klass. He emigrated to America in the early '20s with his parents. He began writing in 1945 after being discharged from the Army, and his first story, "Alexander the Bait," was published a year later. His stories and articles have been widely anthologized, a number of them in best-of -the-year collections. He was a professor of English at Pennsylvania State University, where he taught -- among other things -- a popular course in science fiction. In 1999, he was honored as Author Emeritus by the Science Fiction and Fantasy Writers of America at the Nebula Awards Banquet in Pittsburgh. In 2003, he was the guest of honor at Capclave. In 2004, he was a guest of honor at Noreascon 4, the 62nd World Science Fiction Convention.
He lives with his wife Fruma in suburban Pittsburgh with several cats and many books.
He is not the Philip J. Klass who writes for Aviation Week and Space Technology.
