William Emms (29 January 1930-May 1993) wrote the Doctor Who serial Galaxy 4 in 1965 and also adapted the script for a Target novelisation. Later scripts for the programme from the 1960s to the 1980s were not commissioned. He did however write a Doctor Who gamebook entitled Mission to Venus as part of the Make your own adventure with Doctor Who range.
He was a school teacher who submitted occasional scripts for television.
