In 1919 he went to Stanford University, where he intermittently enrolled in literature and writing courses until he left in 1925 without taking a degree. During the next five years he supported himself as a labourer and journalist in New York City, all the time working on his first novel, Cup of Gold (1929). After marriage and a move to Pacific Grove, he published two Californian fictions, The Pastures of Heaven (1932) and To a God Unknown (1933), and worked on short stories later collected in The Long Valley (1938). Popular success and financial security came only with Tortilla Flat (1935), stories about Monterey’s paisanos. A ceaseless experimenter throughout his career, Steinbeck changed course regularly. Three powerful novels of the late 1930s focused on the Californian labouring class: In Dubious Battle (1936), Of Mice and Men (1937) and the book considered by many his finest, The Grapes of Wrath (1939). Early in the 1940s, Steinbeck became a filmmaker with The Forgotten Village (1941) and a serious student of marine biology with Sea of Cortez (1941).
