Theodore Sturgeon, Storyteller. 1976 Biographical essay by Paul Williams. "Sturgeon because that was the stepfather's name -- he was a professor of modern languages at Drexel Institute in Philadelphia -- and Theodore because Edward was the boy's father's name and the mother was still bitter and anyway young Edward had always been known as Teddy."
op. cit.. "To this day, libraries all over the world list "Theodore Sturgeon" as a pseudonym for "E.H. Waldo, which is incorrect."
