Jacques Jules Boufil was a French composer and clarinetist. He was a pupil of Xavier Lefèvre at the Paris Conservatoire, gaining a First Prize in 1806, which until 1817 carried with it the award of a pair of French-made clarinets in B flat and C.[1]His compositions for clarinet duet and trio are some of the most worthwhile written for the medium. They are full-scale works of considerable substance and were doubtless intended for performance by professionals.
