California Assembly
In 1966 Eu was elected as a Democrat to the California State Assembly from the 15th District, representing Oakland and Castro Valley. She served four terms. She was the first Asian woman elected to a state legislature in the U.S. She is perhaps best known for her successful campaign to ban pay toilets, arguing that they discriminated against women since urinals were free.
Eu was elected Secretary of State of California in 1974, becoming the first Asian American woman ever elected to a state constitutional office in the United States. She remained the only woman to serve as California Secretary of State until 2006, when voters elected Debra Bowen. Eu was elected Secretary of State five times. In 1978 she won every county in the state, even heavily RepublicanOrange County, making her one of only five Democrats to win the county in a statewide race in the last half century. She resigned in 1994 when President Bill Clinton nominated her for an ambassadorship. Innovations she introduced during her 20 years as Secretary of State included voter registration by mail; providing absentee ballots to anyone who requested them; posting results on the Internet; and including candidate statements in ballot pamphlets. In 1976, she became the first woman to serve as Governor of California, serving as acting governor while Governor Jerry Brown was out of the state.
Eu resided both in California and Singapore with her second husband Henry Eu, a multimillionaire industrialist. Her adopted son, Matt Fong, was a Republican activist who served as California State Treasurer for a four-year term that began January 1995. She also had a daughter, Suyin. Her hobbies in retirement included Chinese brush painting and calligraphy. Eu died on December 21, 2017, at age 95, following a fall.
Recognition
In 2019 California's Secretary of State building in Sacramento was named after Eu ; this made it the first state-owned building to be named for an Asian-American woman. The National Notary Association gives an annual March Fong Eu Award to "the individual who or organization that, in the judgment of the Association's Executive Committee, has done the most to improve the standards, image and quality of the office of Notary Public." Eu was the first recipient of the award in 1979, named after her "for her extraordinary leadership in spearheading enactment of progressive Notary reform legislation, despite opposition from powerful lobbies who preferred lower notarial standards."
