David Cohen

David X. Cohen (born David Samuel Cohen') is a writer for The Simpsons and head writer and executive producer of Futurama. Born and known pre-Futurama as David S. Cohen, he changed his name after joining the Writer's Guild of America as there was already another David S. Cohen (The writers guild does not allow members to have the same name). He chose X because it sounded "sci-fi-ish", though has jokingly said that the X would make him "the David Cohen people would remember". He works with Matt Groening on many projects.
