Okay, you'll have to excuse the rather grim nature of the topic, I hope no-one finds it in bad taste.

But basically I got to wondering over the weekend, while pondering on the many actors, writers and production staff we have lost who have worked on Doctor Who down the years, who was the first person to have worked on Doctor Who to have died?

The earliest person I could initially think of was Roger Delgado, who died in 1973. But did anyone to have worked on the show die before this?

Who was the first person we lost?

Si.
