Marine biologist Edward F. Ricketts is perhaps best known as the inspiration for John Steinbeck's most empathic literary characters Doc in "Cannery Row, " Slim in "Of Mice and Men, " Jim Casy in "The Grapes of Wrath, " and Lee in "East of Eden." The correspondence of this accomplished scientist, writer, and philosopher reveals the influential exchange of ideas he shared with such prominent thinkers and artists as Henry Miller, Joseph Campbell, Ellwood Graham, and James Fitzgerald, in addition to Steinbeck, all of whom were drawn to Ricketts's Monterey Bay laboratory, a haven of intellectual discourse and Bohemian culture in the 1930s and 1940s. The 125 previously unpublished letters of this collection, housed at the Stanford University Library, document the broad range of Ricketts's interests and accomplishments during the last 12 and most productive years of his life.
