Sigrid Lorenzen Rupp graduated from UC Berkeley in 1966 and was one of the notable California women architects practicing architecture in the San Francisco Bay Area from 1966-2004 until the until her untimely death from gastric cancer in 2004. Sigrid was “a pioneer and a risk taker… someone who could quickly garner the respect of the community and above all someone with the perseverance to succeed ” (Steven Rupp, former husband).

Born in Bremerhaven Germany in 1943 and emigrated to California with her family in 1953, Sigrid was a champion of women’s rights. Sigrid started her own firm SLR Architects in 1976 in the face of all odds in competition with other architectural firms in the Silicon Valley. SLR Architects offered opportunities for many young professionals, especially women and minorities to launch their architectural careers. Sigrid was a wonderful person and a thoroughly competent architect who was highly dedicated to the profession.

Sigrid also became involved in women’s issues and political affairs, “…simply because I did not want there to be any (women’s issues). It seemed that the time for gender differences should long be over.”
