The gentleman was a lawyer and one of America's favorite authors. Apparently he found the practice of the law to be a bit tedious, and in order to spice up his life he took to writing stories for pulp magazines, a popular medium of the day. This work led to a career as an author. He is doubtless best known for his characters, Perry Mason and Della Street. He wrote more than eighty books featuring Mason. These stories were presented not only in print, but also via radio, cinema, and television. There is scarcely an American of a certain age who does not remember Perry Mason, whether or not he can name the author.
Yet this author seemed to be on occasion uncertain of what name he wished to use, for he has been published in both fiction and non-fiction works under seven or eight different names. When a crook masquerades under a false name, it is referred to as an alias. When an author does it, it is called a pseudonym. But you knew that from your fourth-grade reading class, if you were paying attention.
