Maurice Zimm (June 19, 1909 – November 17, 2005) was an American radio, television and film writer, whose most famous creation was the Creature from the Black Lagoon. The son of Jewish immigrants who settled in Iowa shortly after the turn of the century, Zimring moved to Los Angeles in the 1930s, and wrote for such mystery and drama radio series as Hollywood Star Playhouse and Murder By Experts under the pen name of Maurice Zimm.
Born Maurice Zimring in Waterloo, Iowa, United States, his career transitioned to film when Metro-Goldwyn-Mayer studios bought his radio script, "A Question Of Time", to be adapted into the 1953 Barbara Stanwyck film, Jeopardy (also released under the title A Woman in Jeopardy). Zimring’s next project was developing the storyline for Creature from the Black Lagoon for producer William Alland. Alland had been developing an idea about a half-man/half-fish creature, after being told of such a legendary creature by the Mexican cinematographer Gabriel Figureoa, at a dinner party at Orson Welles' home. Zimm produced a 59-page story treatment, which was developed into a screenplay by Harry Essex and Arthur A. Rose.
In 1955, Zimm worked on an early draft of the adaptation of the Tom Lea western novel, The Wonderful Country, although he would receive no credit when the film was eventually released in 1959. Later that year, Zimm received his first full screenplay credit for the Biblical epic The Prodigal starring Lana Turner. He followed this up with penning the noir Affair in Havana (1957) which starred John Cassavetes and Raymond Burr. Zimm's final film was the 1959 western Good Day for a Hanging featuring Fred MacMurray.
