Quentin Claudian Stephen Bell (1910–1996) was an English art historian, author, potter and painter. He was the son of Clive Bell and Vanessa Bell and a nephew of Virginia Woolf. He wrote Virginia Woolf: A Biography (1972), which won the James Tait Black Memorial Prize and the Duff Cooper Prize. He married Anne Olivier Popham in 1952. His other books include Bloomsbury (1968) and The Art of Bloomsbury. He taught at several universities, including Sussex.

The National Portrait Gallery holds photographic portraits by Quentin Bell, including a 1937 bromide print of Virginia Woolf. The collection record identifies Bell as a photographer as well as an art historian and author. These photographs document members of the Bloomsbury Group and form part of the Gallery’s primary collection. The NPG’s holdings provide evidence of Bell’s photographic practice alongside his better-known work as a writer and potter.
