John Steinbeck was born in 1902 in Salinas, California, a region that became the setting for much of his fiction, including Of Mice and Men. As a teenager, he spent his summers working as a hired hand on neighboring ranches, where his experiences of rural California and its people impressed him deeply. In 1919, he enrolled at Stanford University, where he studied intermittently for the next six years before finally leaving without having earned a degree.

Of Mice and Men followed in 1937, and The Grapes of Wrath won the 1940 Pulitzer Prize and became Steinbeck’s most famous novel. Steinbeck sets Of Mice and Men against the backdrop of
