a German pianist and composer born in Mannheim, Germany. Among his many musical works, he was involved with the composition in 1837 of Hexaméron (six composers contributed). An earlier collaborative work, from 1819–1823 (this time involving 51 composers) was Vaterländischer Künstlerverein, an anthology of variations on a waltz by Anton Diabelli, which also included Ludwig van Beethoven's Diabelli Variations.
