Bertha Knight Landes, elected mayor of Seattle in 1926, became the first woman to lead a major American city. She ran on a platform of "municipal housekeeping," vowing to clean up city government. She advocated municipal ownership of utilities such as City Light and street railways. Her single term ended in 1928, but she remained a civic leader and role model for women.

Landes turned the tide of widespread corruption in city government with an honest, scandal-free administration. She appointed qualified professionals to head city departments, improve public transportation and parks, and put the city's financial house in order.
One of her administration's legacies is the Civic Auditorium (renovated as the Seattle Opera House for the 1962 World's Fair), for which she broke ground.

Seattle will soon elect its first female mayor in more than 90 years.

With women claiming the top four spots in Tuesday’s primary-election results ― Jenny Durkan, Cary Moon, Nikkita Oliver and Jessyn Farrell ― the city on Nov. 7 will choose a woman as mayor for the first time since Bertha Landes‘ election in 1926.

Landes was the first woman to lead a major U.S. city.

“Throughout her brief political career, Landes had to prove herself in ways that men did not — facing constant scrutiny over whether her dress and demeanor were proper for a woman of the early 20th century,” a Seattle Times 2013 story says.
