Schwarz (1800-1867) was the son of a Viennese fur dealer. His father sent him to Detroit to establish contacts with local fur traders. He was recalled to Vienna after the death of his father; he brought numerous Native American made objects back with him, to which he added to the collection over the decades withou returning to North America. "In 1827 Schwarz became U.S. consul in Vienna, and he kept in touch with his half-brother Johann Evangelist Schwarz, ‎who took up residence in Detroit and as an officer in the Michigan Militia attended various ‎Indian treaties in the state. By far the most significant addition to his collection was the ‎acquisition of the North American Indian collection of Bishop Frederick Résé of Detroit ‎in about 1838, who thus expressed his gratitude to Schwarz for his role in the establishment ‎of the Leopoldine Foundation, an Austrian organization supporting Catholic missionary ‎work in the diocese of Detroit (Kasprycki and Krpata 1988, Kasprycki 1999)."
