Dianne Goldman Berman Feinstein (/ˈfaɪnstaɪn/; born Dianne Emiel Goldman; June 22, 1933) is an American politician who has served as the senior United States senator from California since 1992. A member of the Democratic Party, she was 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 served as the board's first female president in 1978, during which time 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 very popular mayor and was named the most effective mayor in the country by City & State in 1987. (Source: Wikipedia.org, CC BY-SA)
