Joyce Windsor (21 January 1932 – 15 October 2008) was an English-born actress perhaps best remembered for her portrayal of the cleaner Ruby in the BBC1 Comedy Butterflies by Carla Lane. She trained at RADA before working in Rep, then taking time away from the stage to have her children. She returned to acting in the late sixties with small parts in Dixon of Dock Green, Z-Cars, Doctor Who and guesting in The Two Ronnies, playing Ronnie Barker's double and appearing in sketches including the Short and Fat Minstrel Show.
