Perl Gold was a brand name of German musical instrument distributor Kurt Gropp. Kurt Gropp opened his mail order business in 1922 in Siebenbrunn near Markneukirchen, and then moved it to Breitenfeld in 1925. Kurt Gropp's two sons: Gerhard Gropp (1931 - 1999) and Armin Gropp were both master luthiers. Kurt Gropp traded as a private company until April 1972 when it was forcibly nationalized and became part of the VEB group trading under the name VEB Perl Gold until 1975 and then VEB Sinfonia Markneukirchen. In 1979 Kurt Gropp died at the age of 78 years. Armin Gropp and his son Mario Gropp restarted the Gropp business as a private company after the reunification of Germany in 1990.
