Eugène Gigout
A student of Camille Saint-Saëns, he served as the organist of Saint-Augustin Church in Paris for 62 years. He became known as a teacher. Also, his output as a composer was large and of high quality. Renowned as an expert improviser, he also founded his own music school. His nephew-by-marriage, Leon Boëllmann, became another fine organist and composer for the organ (but died at the very young age of 35).
