In 1940 Ricketts and Steinbeck journeyed to the Sea of Cortez (Gulf of California) in a chartered fishing boat to collect invertebrates for the scientific catalog in their book, "Sea of Cortez". Also in 1940, Ricketts began a relationship with Eleanor Susan Brownell Anthony "Toni" Solomons Jackson, who became his common-law wife. As Steinbeck's secretary, Jackson helped edit "The Log From the Sea of Cortez". Jackson, who had attended the University of California, Los Angeles, was the daughter of Katherine Gray Church and Theodore Solomons, an explorer and early member of the Sierra Club, who had discovered and defined the John Muir Trail. Jackson and her young daughter Katherine Adele moved in with Ricketts and lived with him until 1947. In addition to Steinbeck, their circle of friends included the novelist and painter Henry Miller and the mythologist, writer, and lecturer Joseph Campbell.
