Geoffrey Bayldon

Geoffrey Bayldon (born 7th January 1924) played Organon in DW: The Creature from the Pit. He also voiced the Doctor in DWU: Auld Mortality and DWU: A Storm of Angels. Being 80 years at the time that the latter was recorded, he is the oldest actor to play the Doctor in any medium to date. During the 1960s, he was considered for the roles of both the First and Second Doctors.

He was the longtime partner of fellow Doctor Who guest star Alan Rowe. He is best remembered as Catweazle in the 1970s ITV series of the same name.
