10 August 1929: birth of Peter Diamond, who was fight arranger for eight stories between The Dalek Invasion of Earth (First Doctor, 1964) and The Dæmons (Third Doctor, 1971), and played a number of minor parts of which the most important was Delos in The Romans (First Doctor, 1965).
10 August 1939: birth of Kate O'Mara, who played the Rani in The Mark of the Rani (Sixth Doctor, 1985) and Time and the Rani (Seventh Doctor, 1987).
10 August 1996: death of Rex Tucker, who directed The Gunfighters (First Doctor, 1966) but had also been an important force behind the scenes of the creation of Doctor Who in 1963. Following a dispute with Innes Lloyd his credit as producer was excised from episode 4 of The Gunfighters, so the on-screen evidence of his contribution to the show is even slimmer.
ii) broadcast anniversary
10 August 1968: broadcast of episode 1 of The Dominators, the earliest H2 start for any full Doctor Who season. The Second Doctor, Jamie, and new companion Zoe land on an island on the planet Dulkis; so do two sinister Dominators, Toba and Rago, with their robot servants, the Quarks; so do a group of young Dulkians led by Cully, who sees the Dominators casually kill off his friends and then tries to get help. At the end of the episode, the Quarks ask permission to destroy the Doctor and Jamie... The costuming of the native Dulkians is not the show’s finest hour.
