Shimon Wincelberg was a television writer and playwright who wrote or co-wrote two scripts for first season episodes of Star Trek: The Original Series using the nom de plume S. Bar-David (meaning “Shimon, Son of David” in Hebrew). He also wrote “Lord Bobby’s Obsession” for the aborted Star Trek: Phase II series.

His family was forced to flee his native Germany by the Nazi pogroms, arriving in the United States in the late 1930s. He became a professional writer in 1953 with the sale of his first story. He started his career writing short stories for magazines, such as Harper’s Bazaar, New Yorker and Punch. Subsequently, he worked steadily on television programs, plays, and books (some with his wife Anita, also a writer). In science fiction circles, he is probably best known for writing the first five-episode arc of the television series Lost in Space (starring Bill Mumy), as well as the pilot episode to another Irwin Allen science-fiction series The Time Tunnel (starring James Darren, Lee Meriwether and Whit Bissell). Outside of science fiction, Wincelberg worked on television series such as The Naked City (“Alive and Still a Second Lieutenant”, directed by Ralph Senensky), The Wild Wild West (“The Night of the Infernal Machine”, with Jon Lormer), Gunsmoke (“The Judgment”, with William Windom), and Have Gun – Will Travel, on which Gene Roddenberry worked as a frequent writer.

Born in Kiel, Germany, he wrote for many television shows from the 1950s, sometimes under the pen names of S. Bar-David, Shimon Bar-David, Simon Wincelberg, Nicholas B., and Simon Winvelberg.

He died in 2004 in a hospital in Los Angeles, California, USA following a long illness.
