Artist, writer and poet who described herself as “one who regards the arts as a many-faceted crystal rather than as personified by separate Muses”. She was married to the writer and critic Bonamy Dobrée, professor of English literature at the University of Leeds, 1936–55. The Dobrées’ archive is held by the University, which put on a show of Valentine’s paintings and collages in 2000. She exhibited with the LG and Salon des Indépendants, Paris, in the early 1920s, when her friends included the artists Dora Carrington and Mark Gertler. Her early figure paintings diversified into analytical Cubism and Surrealism. From the early 1930s she experimented with collage, a show being held at the ICA, 1963. Dobrée published two novels, Your Cuckoo Sings by Kind, 1927, and The Emperor’s Tigers, 1929, and a book of short stories, To Blush Unseen, 1935.
