ZUMPE, JOHANN CHRISTOPH

born 1735, Saxony? died 1800, Germany German pianoforte maker and builder of the earliest known British piano (1766). Zumpe was an apprentice of the renowned German instrument builder Gottfried Silbermann. Migrating to England in the 1750s, he worked for the Swiss-born harpsichord builder Burkat Shudi (Burkhardt Tschudi) before beginning independent work by 1761. Zumpe made mostly square pianos with a single action, a simple mechanism well suited to domestic instruments and later widely used by other builders. The quality and economy of Zumpe's pianos earned him a fortune; he had several partners, and, when he returned to Germany in 1784, he left a flourishing business to his successors, Schoene and Company. A Zumpe piano was played by Johann Christian Bach when he performed the first piano solo ever heard in an English concert in London in 1768. Zumpe also engaged in making citterns (guitarlike instruments) and built at least one claviorganum, a combination piano and pipe organ.
