Pierre-Louis-Philippe Dietsch (also Dietch, Dietzch, Dietz) (17 March 1808 – 20 February 1865) was a French composer and conductor,[1] 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.[1][2]
