The Hinzen & Rosen Piano Company was established in 1859 in Louisville, Kentucky. Their factory was located between 18th & 19th Street on Grayson Street, and showroom located on Market Street. Little is known about Hinsen & Rosen, and it appears that they were distributed primarily throughout the Southern United States. There seems to be no mention of Hinzen & Rosen after about 1890, indicating that the firm was closed before the turn-of-the-century.
