Clare 'Tony' Atwood (11 May 1866 – 2 August 1962) was a British painter of portraits, still life, landscapes, interiors and decorative flower subjects. Atwood lived in a ménage à trois with the dramatist Christabel Marshall and the actress, theatre director, producer and costume designer Edith Craig from 1916 until Craig's death in 1947.
Atwood was born in 1866 at Richmond, London, the only daughter of Frederick Atwood, an architect, and his wife, Clara Becker. Named Clara at birth, she later used the form Clare and was also known as Tony. Atwood studied at Westminster School of Art and the Slade School of Fine Art. She first exhibited at the New English Art Club in 1893, becoming a member in 1912. She held an exhibition of her work at the Carfax Gallery in 1911. In 1917, during World War I, she was commissioned to paint war scenes for the Canadian Government through the Canadian War Memorials Fund. The Fund arranged for Atwood to visit the military camp at Folkestone in Kent to gather ideas for the work. However, instead Atwood decided to paint a YMCA canteen at one of London’s railway stations, where enlisted men were waiting for a train to take them to camps or to the front. In 1920 she was commissioned for four war paintings by the Imperial War Museum.
A lesbian, in 1916 she joined the writer Christabel Marshall and the actress and stage director Edith Craig in a ménage à trois at Tenterden in Kent until Craig's death in 1947, according to Michael Holroyd in his book A Strange Eventful History. Atwood designed props for several of Edith Craig's productions with the Pioneer Players, including the 16 foot high crucifix for their production of Paul Claudel's The Hostage. Atwood was a member of the Pioneer Players. Atwood occasionally performed at the Barn Theatre at Smallhythe Place in Kent, which was founded by Craig to stage performances in memory of her late mother, the actress Ellen Terry. Atwood acted in the matinée at the Palace Theatre, London on 23 April 1929, held to raise funds for the Ellen Terry Memorial. In July 1932, Atwood decorated the shoe for Craig's production of The Shoe in Tenterden. After Craig's death, Atwood wrote an essay about Craig.
Atwood's paintings are exhibited in the Tate Collection in London, as well as in Glasgow, Manchester and Liverpool. She exhibited at the Royal Academy, and in 1940 one of her paintings was purchased by the National Art Gallery of New Zealand.
Atwood suffered a fractured femur, senile myocarditis and heart failure, and died at Kench Hill Nursing Home, Tenterden, Kent, on 2 August 1962.
