Harry Britt (born June 8, 1938) is a political activist and former supervisor for San Francisco, California.
 Britt was involved during the late 1960s in the civil rights movement when he was a Methodist minister in Chicago.
 He was first appointed to the San Francisco Board of Supervisors in January 1979 by Mayor Dianne Feinstein, succeeding Harvey Milk, who was assassinated in City Hall along with Mayor George Moscone by former Supervisor Dan White.
Ella Hill Hutch (June 9, 1923 – February 25, 1981) was elected to the San Francisco Board of Supervisors in San Francisco, California, in 1977 (along with Harvey Milk and Dan White) and reelected in 1980.
 She was the second African American elected to the Board (Terry Francois was the first, elected in 1967, 1971, and 1975), and the first African-American woman.
 Hutch took part in many offices before her service on the Board in 1977.
 She started her career among the International Longshore and Warehouse Union for 25 years , then branched off and became more politically active concerning policy and political issues within San Francisco.
 She took part in several councils and boards, including the Democratic County Central Committee in 1966, the Fillmore Tenants Council, the Bay Area Rapid Transit (BART) Board, and the Golden Gate Bridge, Highway and Transportation District .
 She took public office in 1977 as the Board of Supervisors for District 4, and later citywide.
 She focused on government-financed housing and public transportation.
Gordon J. Lau (August 22, 1941 – April 20, 1998) was the first Chinese American elected to the San Francisco Board of Supervisors in San Francisco, California.
 He was elected to the city board of supervisors under Mayor George Moscone in 1977.
 Other notable supervisors at the time included Dianne Feinstein, Carol Ruth Silver, Quentin L. Kopp, Dan White, and Harvey Milk (the first openly gay individual to serve).
 Much like his colleague Milk, who had been an important activist for the LGBT community of San Francisco, Lau was an activist for the city's Asian American community.
 Gordon J. Lau Elementary School in Chinatown is named in his honor.
Dianne Feinstein became mayor pro-tem of the City and County of San Francisco, California on December 4, 1978, following the Moscone–Milk assassinations in which her predecessor in office, George Moscone and fellow member of the San Francisco Board of Supervisors, Harvey Milk, were assassinated by former supervisor Dan White.
 At the age of 45, Feinstein became the first (and, to date, only) female mayor of the municipality, and was formally elected to the position on November 4, 1979 and re-elected in 1983.
 She was prevented from seeking a third term in office and was succeeded in 1987 by Art Agnos.
Milk is a 2008 American biographical film based on the life of gay rights activist and politician Harvey Milk, who was the first openly gay person to be elected to public office in California, as a member of the San Francisco Board of Supervisors.
 Directed by Gus Van Sant and written by Dustin Lance Black, the film stars Sean Penn as Milk and Josh Brolin as Dan White, a city supervisor who assassinated Milk and Mayor George Moscone.
 The film was released to much acclaim and earned numerous accolades from film critics and guilds.
 Ultimately, it received eight Academy Award nominations, including Best Picture, winning two for Best Actor in a Leading Role for Penn and Best Original Screenplay for Black.
Harvey Bernard Milk (May 22, 1930 – November 27, 1978) was an American politician and the first openly gay elected official in the history of California, where he was elected to the San Francisco Board of Supervisors.
 Despite being the most pro-LGBT politician in the United States at the time, politics and activism were not his early interests; he was neither open about his sexuality nor civically active until he was 40, after his experiences in the counterculture movement of the 1960s.
Daniel James "Dan" White (September 2, 1946 – October 21, 1985) was a member of the San Francisco Board of Supervisors.
 He assassinated San Francisco Mayor George Moscone and Supervisor Harvey Milk, on Monday, November 27, 1978, at City Hall.
 In a controversial verdict that led to the coining of the legal slang "Twinkie defense", White was convicted of manslaughter rather than murder in the deaths of Milk and Moscone.
 White served five years of a seven-year prison sentence.
 Less than two years after his release, he returned to San Francisco and committed suicide.
The Moscone–Milk assassinations were the killings of San Francisco Mayor George Moscone and San Francisco Supervisor Harvey Milk, who were shot and killed in San Francisco City Hall by former Supervisor Dan White on November 27, 1978.
 White was disappointed that Moscone had refused to reappoint him to his seat on the Board of Supervisors, from which White had just resigned, and that Milk had lobbied heavily against his reappointment.
 These events helped bring national notice to then-Board President Dianne Feinstein, who became the first female mayor of San Francisco and eventually U.S. Senator for California.
Tom Ammiano (born December 15, 1941) is an American politician and LGBT rights activist from San Francisco, California.
 Ammiano, a member of the California Legislative LGBT Caucus, served as a member of the California State Assembly from 2008 to November 30, 2014.
 He had previously been a member of the San Francisco Board of Supervisors and had mounted an unsuccessful bid for mayor of San Francisco in 1999.
 He was succeeded as California's Assemblyman for District 17 by San Francisco Board of Supervisors President David Chiu on December 1, 2014.
Anne Kronenberg is an American political administrator and LGBT rights activist.
 She is best known for being Harvey Milk's campaign manager during his historic San Francisco Board of Supervisors campaign in 1977 and his aide as he held that office until he and mayor George Moscone were assassinated.
 As an openly lesbian political activist, Kronenberg was noted for her instrumental role in the gay rights movement, both for Milk's campaign and in her own right, though she has since married a man.
