Louis James Alfred Lefébure-Wély (November 13, 1817, Paris – December 31, 1869, Paris) was a French organist and composer.
Lefébure-Wély played a major role in the development of the French symphonic organ style and was a close friend of the organ builder Aristide Cavaillé-Coll, inaugurating many new Cavaillé-Coll organs. He was organist at the Parisian churches of Saint-Roch (1841-1846), the ãglise de la Madeleine (1847-1857), and Saint-Sulpice (1863-1869). He is the dedicatee of the 12 studies for organ pedals alone by Charles-Valentin Alkan; it has been suggested that this was a sly mockery on Alkan’s part.
Lefébure-Wély is buried in the Père Lachaise cemetery in Paris.
His most celebrated compositions are probably the Sorties in E-flat and B-flat major for organ.
