Lindsay Cooper (born 3 March 1951 - died 18 September 2013) was an English bassoon and oboe player, composer and political activist. Best known for her work with the band Henry Cow, she was also a member of Comus, National Health, News from Babel and David Thomas and the Pedestrians. She collaborated with a number of musicians, including Steve Hillage, Egg, Hatfield and the North, Robert Wyatt, Chris Cutler and Sally Potter, and co-founded the Feminist Improvising Group. She wrote scores for film and TV and a song cycle Oh Moscow, which was performed live around the world in 1987. She also recorded a number of solo albums, including Rags (1980), The Gold Diggers (1983) and Music For Other Occasions (1986).
Cooper was diagnosed with multiple sclerosis in 1991, but did not disclose it to the musical community until 1998, when her illness prevented her from performing live.
