Denis Mitchell was initially a painter but became renowned for his polished bronze sculptures in the 1940's. Mitchell's first sculptures began in wood, slate and stone but after working closely with Barbara Hepworth as her principle assistant between the years of 1949-1959 his style turned to bronze.
Mitchell was a member of the Penwith Society which formed in 1948 and was based in St. Ives. It was formed by abstract artists, who were breaking away from the St Ives Society of Artists, headed by Barbara Hepworth and Ben Nicholson.
Mitchell's work can be seen in various public collections throughout the UK including the Tate, London; The Fitzwilliam Museum, Cambridge and Arts Council of Great Britain, and internationally including Calouste Gulbenkian Foundation Lisbon; National Gallery of New South Wales, Sydney, Australia; and Santa Barbara Museum of Art, Santa Barbara, California, USA. Recent solo exhibitions have included Ascending forms in 2005 at Tate St Ives and Denis Mitchell at Flowers Central, London in 2007.
