Harry Hay, 90, Early Proponent of Gay Rights, Is Dead
By DUDLEY CLENDINEN
"Harry Hay, who founded a secret organization six decades ago that proved to be the catalyst for the American gay rights movement, died early Thursday morning at his home in San Francisco. He was 90."
"Although little known in the broader national culture over the years, Mr. Hay's contribution was to do what no one else had done before: plant the idea among American homosexuals that they formed an oppressed cultural minority of their own, like blacks, and to create a lasting organization in which homosexuals could come together to socialize and to pursue what was, at the beginning, the very radical concept of homosexual rights."
