She is credited with saving the original San Francisco Mint building , known as the " Granite Lady , " by transferring it to the Treasury Department . The building , one of the few to survive the Great Earthquake of 1906 , had been vacant since 1937 and fallen into disrepair . It is now both a National Historic Landmark and a California Historical Landmark . Brooks received the " I Left My Heart In San Francisco " Award in 1974 from the San Francisco Convention and Visitors Bureau for her preservation efforts
