Jacques-Jules Bouffil was a prominent nineteenth-century French clarinetist and composer. Much of the existing biographical information for Bouffil is in French, it is often in obscure locations, and the sources available often contain discrepancies. This document provides the most comprehensive and accurate biography to date of clarinetist and composer Jacques-Jules Bouffil through examination of his studies at the Paris Conservatoire, as well as his performance career with the Paris Opéra-Comique orchestra, the Reicha Wind Quintet, and other organizations. The compositional contributions of Bouffil include a number of chamber music pieces, most notably, six trios for three B-flat clarinets, op. 7 nos. 1-3 and op. 8 nos. 1-3. These six trios comprise some of the most substantial works composed for the medium. They deserve to be better known because of their unusual concertant style writing and compositional rigor. This study offers a new performance edition with rehearsal score of Bouffil’s Trio no. 2, op. 7, a work that is not readily available to modern performers.
