In spite of his protestations, however, muted accusations that Steinbeck was "Red" lingered into the 1950s. In 1939, as The Grapes of Wrath was about to be published, he was convinced that the FBI was investigating him-in Monterey a local bookstore owner reported being questioned by Hoover's men and in Los Gatos his name had been turned into the local sheriff's office. FBI files on Steinbeck uncategorically deny that he was under investigation in the late 1930s, but they do detail a full investigation made of the writer in 1943 "to determine his suitability to hold a commission in the U.S. Army," a commission denied because of suspected communist sympathies. "Associates and friends," the FBI report notes, said that although he "exercised poor discretion during his early days of writing by associating with some elements of the Communist Party, he was not interested in advancing the cause of the Party but in gathering material for his writings on certain social conditions existing in the US at that time." In fact, evidence of communist leanings is decidedly thin: in 1936 and 1938, Steinbeck published two articles in the liberal Carmel magazine owned by Ella Winter and Lincoln Steffens, the Pacific Weekly; in 1936, he also lent his support to and possibly attended the Western Writers Conference, later labeled a "communist front" according to the committee on Un-American Activities; in 1938, he gave his 1936 San Francisco News accounts to the Simon Lubin Society, allegedly "a Communist front for California agrarian penetration"; in 1938, "the Committee to Aid Agricultural Workers was organized under Steinbeck's leadership"; in 1946, he was invited to a reception in New York for three visiting Soviet literary figures. That was it. John Steinbeck was-no communist, but he was very curious about communism's effect on the average man.
