Graham Crowden

Clement Graham Crowden was a Scottish actor. He was best known for his many appearances in television comedy dramas and films, often playing eccentric offbeat scientist, teacher and doctor characters.

Crowden was born in Edinburgh, the son of Anne Margaret and Harry Graham Crowden. He was educated at Clifton Hall School and the Edinburgh Academy before serving briefly in the Royal Scots Youth Battalion of the army until he was injured in a bizarre accident. During arms drill he was shot by his platoon sergeant, when the sergeants rifle discharged. The sergeant reportedly enquired What is it now, Crowden, to which Crowden replied I think youve shot me, sergeant. He later found work in a tannery.
