Louis James Alfred Lefébure-Wély was a French organist and composer who was active in the 19th century. He is best known for his contributions to the organ repertoire and his popularization of the “grande pièce symphonique,” a type of virtuosic organ work that was popular in France during the 19th century.

Lefébure-Wély was born in 1817 in Paris, France, and began studying music at a young age. He later became the organist at the Church of the Madeleine in Paris and was highly influential in the development of the French organ tradition. Lefébure-Wély composed a number of works for organ, including his “Grande Pièce Symphonique in D Minor,” which is considered one of his most important works. He died in 1869 at the age of 52.
