An association of progressive British artists, originally consisting of seven painters and five sculptors, which was established in 1919 and lasted until 1935. It played an important role in encouraging the development of abstract art in Britain. Its founder members were by and large minor figures but by the late 1920s it had become the most important British association of avant-garde artists. Ben Nicholson had joined in 1924 and by 1926 had become chairman. He steered the group increasingly towards abstraction, and its final exhibition, held in 1935 (by which time the group had changed its name to the Seven & Five Abstract Group), was the first show of all-abstract art to have been held in Britain. Both Barbara Hepworth and Henry Moore exhibited in this last group show.
