545	|aLouis Prang (1824-1909) was a lithographer, wood engraver, and educator from Breslau (Germany) and Boston (Mass.). With Julius Meyer, he founded the lithographic business of Prang & Meyer in 1856 which later became L. Prang & Co. Prang reproduced paintings by noted 19th century artists and introduced the Christmas card in the 1870s. He is considered the founder of the greeting card business in the U.S. Prang retired from business in 1899 and died ten years later in a California sanitarium.
545	|aThe reasons for Prang's interest in gold mining and its processes are uncertain; it was certainly a business and investment opportunity. Prang may also have been interested in the gold for its use in ink; one of his partners in the venture, Henry B. Davis, was an officer of the Dando Printing Company of Philadelphia, a printer of elaborate stock certificates. The venture may have been called Monitor Concentrator and Amalgamator, as evidenced by receipts.
520	|aThe collection is comprised of correspondence (including telegrams), receipts, patent documents, and notes concerning Prang's investment and scientific interest in a gold separation process utilizing mining tailings. The correspondence includes detailed reports on gold mines in California and Nova Scotia, discussions of gold concentrators, chlorination, transport of ore to the eastern United States, and business arrangements; correspondents include geographer and geologist William Morris Davis. Documents include receipts and invoices for supplies and services connected with expeditions in 1888 to California. Also included is a receipt for Prang's patent for a separator.
