The California Surveillance Collection consists primarily of undercover agent reports and other materials documenting the
activities of labor organizations and organizations on the left, 1934-1940, including the Communist Party of San Francisco,
and labor leader Harry Bridges. The materials were possibly gathered or created by Harper Knowles during his tenure as director
of the Subversive Activities Committee of the American Legion in San Francisco, and Stanley M. Doyle, an associate of Harper
Knowles. A second series in the collection contains household and financial records of Harper Knowles from 1901-1954.
Harper L. Knowles and Stanley M. Doyle, prominently represented among the documents, were both associated with the Radical
Research Committee, later the Subversive Activities Committee of the American Legion. Knowles, nicknamed "Moke," was the head
of that committee before he became executive secretary of the Associated Farmers. Doyle, also known as Larry Doyle and Stanley
Morton, was designated as a special investigating agent by the governor of Oregon; he worked closely with Knowles, especially
in investigating Harry Bridges.
