Alfred Uhl (June 5, 1909 – June 8, 1992) was an Austrian composer who wrote extensively for clarinet, including educational material and works that are still common repertoire. His most famous educational pieces are the two volumes which comprise the 48 Studies (see below). Uhl studied at the Vienna State Academy of Music and later taught at the same institution. His Divertimento for Three Clarinets and Bass Clarinet is one of the most performed works for the medium. Written in 1942 for clarinettists from the Vienna Philharmonic, it is a very demanding 3-movement work structured similarly to a conventional concerto. Other works include a concerto for clarinet and orchestra (Konzertante Sinfonie for Clarinet and Orchestra) and a trio for clarinet,piano and viola (Kleines Konzert).
