Léon Clément Doucet (9 April 1895 – 15 October 1950) was a Belgian pianist.
He studied for a time at the local Conservatoire, where his teacher, Arthur De Greef, had been a pupil of Franz Liszt.
[1] His formal training was classical, and he traveled to the U.S.[1] Some of his arrangements are still played today,[2] including "Chopinata", a jazz tribute to several works by Frédéric Chopin.
These include ten sides with Maurice Chevalier, and others, solo, with Édith Piaf and Yvonne George (Wiéner) and Jean Sablon and Germaine Sablon (Doucet).
After World War II, Wiéner worked as a broadcaster and composer of film music.
