This book explores the origins and history of the modern American movement for homosexual rights, which originated in Los Angeles in the late 1940s and continues today. Part ethnography and part social history, it is a detailed account of the history of the movement as manifested through the emergence of four related organizations: Mattachine, ONE Incorporated, the Homosexual Information Center (HIC), and the Institute for the Study of Human Resources (ISHR), which began doing business as ONE Incorporated when the two organizations merged in 1995. Pre-Gay L.A. is a chronicle of how one clandestine special interest association emerged as a powerful political force that spawned several other organizations over a period of more than sixty years.

Relying on extended interviews with participants as well as a full review of the archives of the Homosexual Information Center, C. Todd White unearths the institutional histories of the gay and lesbian rights movement and the myriad personalities involved, including Mattachine founder Harry Hay; ONE Magazine editors Dale Jennings, Donald Slater, and Irma Wolf; ONE Incorporated founder Dorr Legg; and many others. Fighting to decriminalize homosexuality and to obtain equal rights, the viable organizations that these individuals helped to establish significantly impacted legal policies not only in Los Angeles but across the United States, affecting the lives of most of us living in America today.
