Dorothy Strachey Bussy was one of 10 children of Lt.-Gen. Sir Richard Strachey, an officer in the British colonial armies and his wife Jane Grant, a leader in the women's suffrage movement. The writer and literary critic Lytton Strachey and translator James Strachey were among her brothers. She was educated at Marie Souvestre's school for girls in Fontainebleau, France, and later in Allenswood Academy, near London, where the school moved. She became a teacher at Allenswood, where one of her students was the young Eleanor Roosevelt, on whom she had a strong influence. In 1903, Dorothy married Simon Bussy, a French painter five years her junior. The couple were associated with The Bloomsbury Group. Dorothy had an affair with Lady Ottoline Morrell, the society hostess and patron of the arts. In 1949, she anonymously published her only novel, Olivia, with the Hogarth Press founded by Leonard and Virginia Woolf. In 1951, it was adapted as a film called Olivia, and made into a BBC radio drama broadcast in the 1990s. Dorothy was also a close friend of André Gide, with whom she conducted a lively correspondence for more than 30 years, and translated some of his works. Their letters are published in Selected Letters of Andre Gide and Dorothy Bussy by Richard Tedeschi, and also in a three-volume French edition.
