The materials in the J. David Latham Psychological Surveys comprise one of sixteen collections of records from the ONE National Gay and Lesbian Archives, the world's largest repository of LGBTQ materials. These files document the lives of LGBTQ individuals from 1940 to 2012, the organizations they founded, the discrimination they faced, and the devastation of the AIDS crisis. Most of the items concern individuals or groups from California. As part of his research on homosexuality within heterosexual marriages and on gay recovering alcoholics, psychologist J. David Latham conducted psychological surveys of subjects from 1977 to 1986. In addition to the surveys, research papers, correspondence, administrative materials, and other research materials, the collection includes a small number of audio recordings as well as correspondence and other miscellaneous writings. This collection is vital for anyone researching the many facets of LGBTQ life in California and the United States in the second half of the twentieth century.
