Franciszek Lessel was a Polish composer renowned for his innovative contribution to the ensemble instrumentation for Grand Trio for Clarinet, Horn and Piano, Op. 4 (1806)
In Vienna, Franciszek rose to fame as a pianist, having composed many piano compositions such as Variations, Sonata op.2, Adagio, and Rondo op.9. He dedicated his famous composition, Fantaisie in E minor, to his lover Cecylia Beydale. Alas, his liaison with the beautiful Cecylia was all too short-lived as it was soon discovered that they had the same mother.
