“Dr. Frank Kameny is widely hailed as one of the most prominent figures of the United States LGBTQ rights movement. …
In 1971, Kameny became the first openly gay candidate for the US Congress when he ran in the District of Columbia’s first election for a non-voting Congressional delegate. After his defeat Kameny and his campaign organization created the Gay and Lesbian Alliance of Washington, DC, an organization that continues to lobby government and press the case for equal rights.”
The following is one of his many quotes:
“The person who really needs the psychotherapy (…) is not the homosexual youngster who gets dragged to the psychiatrist’s office by his mother, but the mother, to releive her anxieties about his homosexuality.”[Source: News 18.]
Dr. Kameny died in 2011. Here is his obituary in the Guardian.
