I have heard the name Ernest Kinoy over and over in recent years as the old archives of broadcast radio have gone online. As an example, look at the episode lists for the two iconic SF radio play series Dimension X and X Minus One from the 50s.[1]
Not only was he involved in the adaptation of nearly every
episode of these two series, but he and his partner George Lefferts also
contributed original pieces. True, much of his work in SF was derivative in the sense of being derived from the short stories of others[2] but radio plays are a very different beast from print, and it's not as though he did no original work of his own: Kinoy contributed 8 wholly original works to these two series, and is credited with the novelization of several dramatic works in addition to adapting work for radio and screen.
