German firm of organ builders and string keyboard instrument makers. Adolf Kemper (1811–80) became a citizen of Lübeck in 1839. His son Emanuel (1844–1933) took over the workshop of Theodor Voigt in 1868 and founded the present firm, which has remained under the control of the original family, from Kempringen, Westphalia. Emanuel’s son Karl Reinhold (1880–1957), well known for his collaboration with H.H. Jahnn, took over the firm in 1910. Karl’s son Emanuel Magnus (b Apenrade, 30 Sept 1906; d Lübeck, 17 March 1978) entered the firm in 1944, and greatly broadened its interests to include clavichords, spinets and harpsichords. On 1 January 1974 Emanuel Reinhold (b Lübeck, 8 Jan 1947), son of Emanuel Magnus, became head of the firm. It is uncertain whether Peter Kemper (b Menden, bap. 18 April 1734; d Bonn, 24 Oct 1820) was a member of this family. He was an organ builder in the tradition of Balthasar König, and his work included the organs in Bonn Minster and Aachen Cathedral....
