Barbara Merriweather-Sims, the city’s first female African American judge, has died.

Mayor Byron Brown announced her death Wednesday, posting his condolences on social media and saying that Buffalo has lost a true pioneer.

Merriweather-Sims, 94, was also the first African American woman to earn a law degree from UB and the first to serve as an assistant district attorney in Erie County.

Sim fought for civil rights, against housing discrimination and to advance the rights of women.
