Jack Williamson
John Stewart Williamson , who wrote as Jack Williamson, was an American science fiction writer, often called the Dean of Science Fiction after the death of Robert Heinlein in 1988. Early in his career he sometimes used the pseudonyms Will Stewart and Nils O. Sonderlund.
Williamson was born April 29, 1908 in Bisbee, Arizona Territory, and spent his early childhood in western Texas. In search of better pastures, his family migrated to rural New Mexico in a horsedrawn covered wagon in 1915. The farming was difficult there and the family turned to ranching, which they continue to this day. He served in the U.S. Army Air Corps in World War II as a weather forecaster.
