Pierre-Louis Dietsch

Pierre-Louis-Philippe Dietsch (also Dietch, Dietzch, Dietz) (17 March 1808 – 20 February 1865) was a French composer and conductor, perhaps best remembered for the much anthologized Ave Maria 'by' Jacques Arcadelt, which he loosely arranged from that composer's three part madrigal Nous voyons que les hommes.
