The M. Schulz Piano Company was a major contributor to the American piano industry at large.  M. Schulz founded his firm in Chicago in 1869.  The firm was later incorporated in 1891 as The M. Schulz Piano Company.  M. Schulz built very high quality pianos and organs, and their instruments enjoyed a stellar reputation for their quality and tone.  The hugely successful M. Schulz Piano Company manufactured and sold pianos under the names of Walworth, Bradford, Irving, Maynard and DeKoven in addition to their premier line of M. Schulz brand pianos.  After the turn-of-the-century M. Schulz manufactured a line of player pianos under the “Aria Divina” brand name.  The large firm of M. Schulz was forced out of business in the early 1930s due to the Great Depression.
