Frederick Bischoff, 1890s – Brooklyn Museum Libraries, Special Collections
German-born Frederick Bischoff (1857-1942) arrived in New York in the 1870s and entered the chocolate business by way of the pharmacy trade. He began manufacturing at 227 West 29th Street in the 1890s. By the turn of the 20th century Bischoff had expanded operations to 3rd Street and 3rd Avenue in the Gowanus neighborhood of Brooklyn, followed by factories on Ashland Place, then Sands Street, and ultimately moving upstate to Ballston Spa, New York in the 1920s. Frederick passed away in 1942 and by 1945 the company folded, purportedly after low sales and limited supplies of cocoa and sugar during the war years.
