John Schmidt and Peter Fieberling were the proprietors of the Pioneer Saloon which was located at 842 Broadway, Oakland during the 1880's.
[Question: So a bit of humor ... if the directory entry reads "SCHMIDT & FIEBERLING (John Schmidt and Peter Fieberling) Pioneer Saloon, 842 Broadway" were these attorneys who had their office in a saloon, or proprietors who ran another business, perhaps a law firm, out of the saloon??]
