George Haas & Sons was a confectioner in San Francisco, California. George Haas established his first candy factory and store, where he made some 200 varieties of candies, in 1868. After selling the business in 1880 he opened a new business two years later in the Phelan Building, designed by William Curlett, which was marketed as the most beautiful candy store in the U.S. and featured on an historic postcard.
