A close friend of W. H. Auden, Isherwood collaborated with him on the dramas The Dog Beneath the Skin (1935), The Ascent of F6 (1936), and On the Frontier (1938), as well as on Journey to a War (1939), a book on China. Isherwood emigrated (1939) to the United States, becoming a citizen (1946). During the 1940s his interests turned to Hinduism; see his Essentials of Vedanta (1969). Among his later works are Prater Violet (1945), The World in the Evening (1954), Down There on a Visit (1962), A Single Man (1964), and Meeting by the River (1967) and a study of his parents, Kathleen and Frank (1971). Isherwood was an early advocate of discarding the taboos against homosexuality, a subject discussed in his memoir, Christopher and His Kind (1972).
