MARCHAND (John-Louis), a native of Lyons, who shares with the celebrated d'Aguin the glory of having carried the art of playing on the organ to the highest degree of perfection. When very young he went to Paris; and happening to be in the chapel of the college of Louis the Great, when they were waiting for the organist to begin divine service, he offered himself in his place. His playing gave so great satisfaction, that the Jesuits kept him in the college, and supplied him with every necessary to perfect his talents. Marchand continued to play the organ of their chapel; and though many advantageous places were offered to him, he always refused to accept them. This disinterested conduct was not solely owing to his gratitude; for he was of so whimsical and independent a disposition of mind, that he was equally careless about reputation and glory. He died at Paris in 1732, at the age of 63. From him we have two books of Pieces for the Harpsichord, much esteemed by the connoisseurs.
