Léon Clément Doucet (9 April 1895 – 15 October 1950) was a Belgian pianist. Doucet was born and died in Brussels. He studied for a time at the local Conservatoire, where his teacher Arthur De Greef had been a pupil of Liszt. Although his formal training was classical, he traveled to the USA around 1920 and by his return in 1923 had developed considerable talent as a jazz pianist. His left-hand technique in particular is clearly influenced by the stride piano style prevalent in New York in the early 1920s. Some of his arrangements are still played today, for instance Chopinata, a jazz tribute to several of the great works of Chopin.
