Homophile organizations—as homosexual groups self-identified in this era—grew in number and spread to the East Coast. Gradually, members of these organizations grew bolder. Frank Kameny founded the Mattachine of Washington, D.C. He had been fired from the U.S. Army Map Service for being a homosexual, and sued unsuccessfully to be reinstated. Kameny wrote that homosexuals were no different from heterosexuals, often aiming his efforts at mental health professionals, some of whom attended Mattachine and DOB meetings telling members they were abnormal.
