American LGBT rights activists

Dorothy Louise Taliaferro "Del" Martin (May 5, 1921 – August 27, 2008) and Phyllis Ann Lyon (November 10, 1924 – April 9, 2020) were an American lesbian couple based in San Francisco who were known as feminist and gay-rights activists.Martin and Lyon met in 1950, became lovers in 1952, and moved in together on Valentine's Day 1953 in an apartment on Castro Street in San Francisco. They had been together for three years when they cofounded the Daughters of Bilitis (DOB) in San Francisco in 1955. This became the first social and political organization for lesbians in the United States and soon had a national reach. They both acted as president and until 1963 successively as editor of The Ladder magazine, which they also founded. They were involved in the DOB until they joined the National Organization for Women (NOW), the first known lesbian couple to do so.
Both women worked to form the Council on Religion and the Homosexual (CRH) at Glide Memorial Methodist Church in northern California to persuade ministers to accept homosexuals into churches. The couple used their influence to decriminalize homosexuality in the late 1960s and early 1970s. They became politically active in San Francisco's first gay political organization, the Alice B. Toklas Democratic Club. This group influenced then-mayor Dianne Feinstein to sponsor a citywide bill to outlaw employment discrimination for gays and lesbians. Both women remained politically active, later serving in the White House Conference on Aging in 1995.
They were married on February 12, 2004, in the first same-sex wedding to take place in San Francisco after Mayor Gavin Newsom ordered the city clerk to begin providing marriage licenses to same-sex couples. That marriage was voided by the California Supreme Court on August 12, 2004.After the California Supreme Court's decision in In re Marriage Cases legalized same-sex marriage in California, the couple married again on June 16, 2008. Theirs was the first same-sex wedding to take place in San Francisco . Two months later on August 27, 2008, Martin died in San Francisco from complications of an arm bone fracture. Lyon died years later on April 9, 2020.

Warren Allen Smith (October 27, 1921 – January 9, 2017) was an American writer, humanist and gay rights activist. A World War II veteran and an outspoken atheist, he dubbed himself as "the atheist in a foxhole".

Jane Vance Rule (28 March 1931 – 27 November 2007) was a Canadian-American writer of lesbian-themed works. Her first novel, Desert of the Heart, appeared in 1964, when gay activity was still a criminal offence. It turned Rule into a reluctant media celebrity, and brought her massive correspondence from women who had never dared explore lesbianism. Rule became an active anti-censorship campaigner, and served on the executive of the Writers' Union of Canada.

Eve Kosofsky Sedgwick (; May 2, 1950 – April 12, 2009) was an American academic scholar in the fields of gender studies, queer theory, and critical theory. Sedgwick published several books considered groundbreaking in the field of queer theory, and her critical writings helped create the field of queer studies, in which she was one of the most influential figures. Sedgwick's essays became the framework for critics of poststructuralism, multiculturalism, and gay studies.In her 1985 book Between Men, she analyzed male homosocial desire and English literature. In 1991, she published "Jane Austen and the Masturbating Girl", an article that received attention as part of an American culture war and criticism for associating the works of Jane Austen with sex. She coined the terms homosocial and antihomophobic.Sedgwick argued that an understanding of virtually any aspect of modern Western culture would be incomplete if it failed to incorporate a critical analysis of modern homo/heterosexual definition. Drawing on feminist scholarship and the work of Michel Foucault, Sedgwick analyzed homoerotic subplots in the work of writers like Charles Dickens and Henry James. Her works reflected an interest in a range of issues, including queer performativity, experimental critical writing, the works of Marcel Proust, non-Lacanian psychoanalysis, artists' books, Buddhism and pedagogy, the affective theories of Silvan Tomkins and Melanie Klein, and material culture, especially textiles and texture.

Louis Graydon Sullivan (June 16, 1951 – March 2, 1991) was an American author and activist known for his work on behalf of trans men. He was perhaps the first transgender man to publicly identify as gay, and is largely responsible for the modern understanding of sexual orientation and gender identity as distinct, unrelated concepts.Sullivan was a pioneer of the grassroots female-to-male (FTM) movement and was instrumental in helping individuals obtain peer-support, counselling, endocrinological services and reconstructive surgery outside of gender dysphoria clinics. He founded FTM International, one of the first organizations specifically for FTM individuals, and his activism and community work was a significant contributor to the rapid growth of the FTM community during the late 1980s.
