The 1989 Loma Prieta earthquake caused the gallery at Grant Avenue to close , shortly after Fraenkel and business partner Frish Brandt had invested $ 300,000 into the gallery 's expansion . The earthquake also destroyed the spaces occupied by other galleries around Union Square and a number of them , including Fraenkel Gallery , migrated to 49 Geary Street
