Dietrich Fischer-Dieskau (28 May 1925 – 18 May 2012) was a German lyric baritone and conductor of classical music, one of the most famous Lieder (art song) performers of the post-war period, best known as a singer of Franz Schubert's Lieder, particularly "Winterreise" of which his recordings with accompanist Gerald Moore and Jörg Demus are still critically acclaimed half a century after their release.
Recording an array of repertoire (spanning centuries) as musicologist Alan Blyth asserted, "No singer in our time, or probably any other has managed the range and versatility of repertory achieved by Dietrich Fischer-Dieskau. Opera, Lieder and oratorio in German, Italian or English came alike to him, yet he brought to each a precision and individuality that bespoke his perceptive insights into the idiom at hand." In addition, he recorded in French, Russian, Hebrew, Latin and Hungarian. He was described as "one of the supreme vocal artists of the 20th century" and "the most influential singer of the 20th Century".
