Widor, ( pronounced Vidor) Charles-Marie Jean Albert
(21 February 1844 – 12 March 1937) was a French organist, composer and teacher, most notable for his ten organ symphonies. The Toccata of his Fifth Symphony is the only one that I ever listen to and it's extremely popular. Charles Marie Widor: Symphonie Nr. 5 f-moll op. 42,1 - 5. Toccata - YouTube
