Castro and Market Streets

The Friends of 1800 have long advocated for the City of San Francisco to do a comprehensive Cultural Resource Survey of the entire city that will enhance the ability to preserve important buildings on their general historical and aesthetic merits. A Cultural Resource Survey is a basic tool that lays the foundation for the preservation of sites important to LBGT history and culture, and an official recognition of the importance of LGBT history to the culture and history of San Francisco. → More about this.

Tom played a critical role in saving and landmarking the historic Fallon Building at 1800 Market St. that had been targeted for demolition. He had the foresight to extend the group's outreach with an online presence in 1998, as well as network with both local and national organizations. Tom Mayer's passion and energy will live on in the hearts and minds of all those he inspired.

“Tom Mayer approached me while I was on the National Trust for Historic Preservation's San Francisco Regional Office staff. He told me about the pending demolition of the Fallon Building under consideration by the LGBT Community Center of San Francisco Board of Directors. Tom was quite adamant about the National Trust's involvement. He understood broader issues; he also knew the political battlefield and conflicts surrounding the proposed project. Tom encouraged me to participate in Friends of 1800 meetings and to become involved in the effort. Mr. Meyer was bright, outspoken and very passionate about the cause.”

—Gerry Takano, former FO1800 Board President

Over the years Tom Mayer regularly contributed to San Francisco print and online publications in addition to Wikipedia. His final articles are featured at CineSourceMagazine and Hoodline, covering the 2015 San Francisco Jewish Film Festival.
