Djuna Barnes was an American writer who played an important part in the development of 20th century English language modernist writing and was one of the key figures in 1920s and 30s bohemian Paris after filling a similar role in the Greenwich Village of the teens. Her novel Nightwood became a cult work of modern fiction, helped by an introduction by T. S. Eliot. It stands out today for its portrayal of lesbian themes and its distinctive writing style.
