28 July 1912: birth of Colin Douglas, who played security chief Donald Bruce in The Enemy of the World (Second Doctor, 1967) and lighthouse keeper Reuben in Horror of Fang Rock (Fourth Doctor, 1977).
28 July 1938: birth of David Weston, who played the valiant Nicholas Muss in the story we now call The Massacre (First Doctor, 1966) and Tharil leader Biroc in Warrior's Gate (1981). No pictures of The Massacre survive.
Not much else, I'm afraid. More tomorrow.
