Curt Siodmak (1902-2000) was a novelist and screenwriter, author of the novel Donovan's Brain, which was made into a number of films. He also wrote the novels Hauser's Memory and Gabriel's Body.

Born in Dresden, Germany, in 1902, Curt Siodmak worked as an engineer and a newspaper reporter before entering the literary and movie fields. It was as a reporter that he got his first break (of sorts) in films: in 1926 he and his reporter-wife hired on as extras on Fritz Lang (I)'s Metropolis (1927) in order to get a story on the director and his film. One of Siodmak's first film-writing assignments was the screenplay for the German sci-fi picture F.P.1 antwortet nicht (1932) (US title: "Floating Platform 1 Does Not Answer"), based on his own novel. Compelled to leave Germany after Adolf Hitler and the Nazis took power, Siodmak went to work as a screenwriter in England and then moved to Hollywood in 1937. He got a job at Universal through his director-friend Joe May (I), helping write the script for May's Invisible Man Returns, The (1940). Because the film went over well, Siodmak says, he fell into the horror/science-fiction "groove."
