In 1936, a reporter named John Steinbeck wrote a series of articles for the San Francisco News about the struggles of California migrant farmworkers. Three years later, the Salinas native published "The Grapes of Wrath," a novel based in part on those investigations. The best-selling book sparked literary and political controversy, but went on to win a Pulitzer Prize and has long been recognized as an American classic. We talk with leading Steinbeck scholars about the book's enduring impact and legacy.
