Andreas Marschall (1783-1842) was a piano maker in Denmark, however he was born in Hungary and trained in Kassel, Germany. In 1810, Marschall came to Copenhagen and worked for Peter Christian Uldhal (1778-1820) until he opened his own workshop in 1813. Marschall’s primary contribution to the world of piano manufacturing was his training of some of the most important future makers in Scandinavia. Several of his students include John Gustaf Malmsjö (1815-1891) from Sweden and Emmanuel Schöne and Christopher Tomle (1794-1858) of Norway. Upon Marschall’s death in 1842, the firm went to his son, Hjorth.
