Students included flutist-composer Hermann Schmidt (1810–1845) (see Wikipedia (German).) Should not be confused with his younger brother Julius/Jules (also "J.") Gabrielski (born 1806, died 1878), also a flutist, brief entry in Fétis page 371. Fétis identifies Julius' father as Polish in birth and a "sous-officier d’artillerie" (in the Prussian army?).
