(written from a Production point of view)
Between 1950 and 1982, Palmer (birth name Palmer Lee) had roles in various TV programs such as The Lone Ranger, Gunsmoke (twenty episodes), Bonanza (five episodes), Rawhide, Tarzan (three episodes), Mission: Impossible, Jason King, Alias Smith and Jones, and Quincy, M.E. His film roles include Chisum, The McKenzie Break, and The Shootist.
He also made three credited appearances in two Doctor Who serials, firstly as two Cybermen, Shav and Gern in The Tenth Planet (which introduced the Cybermen) in 1966 and then as Lieutenant Lucke in The War Games (which formally introduced the Time Lords) in 1969. These stories were the swansongs of the First Doctor, William Hartnell, and the Second Doctor, Patrick Troughton, respectively. Aside from Troughton, Palmer is the only actor to appear in both stories. Although uncredited in his Star Trek role, Palmer is one of very few actors who have appeared in both the Star Trek and Doctor Who franchises and, more specifically, the only one to appear in both the original Star Trek and the original Doctor Who.
Palmer now lives in Encino, California and is an avid golfer. His wife, Ruth Palmer died in 1999. He has attended the Golden Boot Awards but has not won the award himself.
