Dianne Emiel Feinstein (née Goldman; June 22, 1933 – September 29, 2023) was an American politician who served as a United States senator from California from 1992 until her death in 2023. A member of the Democratic Party, she previously served as the 38th mayor of San Francisco from 1978 to 1988.
A San Francisco native, Feinstein graduated from Stanford University in 1955. She was elected to the San Francisco Board of Supervisors in 1969 and immediately became the board's first female president upon her appointment in 1970. In 1978, during a third stint as the board's president, the assassinations of Mayor George Moscone and City Supervisor Harvey Milk drew national attention. Feinstein succeeded Moscone as mayor and became the first woman to serve in that position. During her tenure, she led the renovation of the city's cable car system and oversaw the 1984 Democratic National Convention. Despite a recall attempt in 1983, Feinstein was a popular mayor and was named the most effective mayor in the country by City & State in 1987.
