Diethard Hellmann (28 December 1928 – 14 October 1999) was a German Kantor and an academic in Leipzig, Mainz and Munich.
Born in Grimma, Dietmann Hellmann was a member of the Thomanerchor. He studied church music in Leipzig with Günther Ramin. Hellmann was the organist for early recordings of Bach cantatas by Ramin. He was Kantor at the Friedenskirche in Leipzig from 1948 to 1955. At the same time, he was a teacher for organ at the Musikhochschule Leipzig, conducting the choir of the Hochschule, and until 1951, a teacher at the Fürstenschule in Grimma. In 1950, he won a prize for organ at the first International Bach Competition. He started teaching choral conducting in 1952 and was appointed vice director of the department for church music in 1954.
In 1955, he became Kantor of the Christuskirche in Mainz, where he conducted the Kantorei, which in 1965, was named the Bachchor (German). In November 1955, he performed a concert of Bach cantatas. In 1958, he was awarded a prize by German broadcaster Südwestfunk (SWF) for his composition Musik auf Christi Himmelfahrt (Music for Ascension).
Hellmann was a teacher for Protestant church music at the Peter Cornelius Conservatory of Mainz, and from 1963, at the Johannes Gutenberg-Universität Mainz as well. He published sheet music, including reconstructions of Bach's Ärgre dich, o Seele, nicht, BWV 186a for the Third Sunday in Advent, Singet dem Herrn ein neues Lied, BWV 190 and the St Mark Passion.
Hellmann took the Bachchor on concert tours to France, Poland and Israel. He collaborated with singers such as Peter Schreier, Aldo Baldin, Ria Bollen, Ursula Buckel, Eva Csapó, Agnes Giebel, Julia Hamari, Ernst Haefliger, Philippe Huttenlocher, Georg Jelden, Helena Jungwirth, Siegfried Lorenz, Adalbert Kraus, Horst Laubenthal, Karl Markus, Barbara Martig-Tüller, Friedreich Melzer, Klaus Mertens, Siegmund Nimsgern, Ernst-Gerold Schramm, Verena Schweizer, Jakob Stämpfli, Ortrun Wenkel, Kurt Widmer and Edith Wiens. They recorded more than 100 Bach cantatas, broadcast by SWF once a week.
Hellmann conducted the Requiem of Jean Gilles, Haydn's Harmoniemesse, the Oratorio de Noël of Saint-Saëns, Beethoven's Missa Solemnis, the four Choralkantaten of Max Reger, and Frank Martin's Golgotha.
Hellmann died in 1999 in Deisenhofen. In a memorial service in the Christuskirche, the Bachchor performed Bach's Es erhub sich ein Streit, BWV 19, because Hellmann had loved the tenor aria Bleibt, ihr Engel, bleibt bei mir! (Stay, ye angels, stay with me).
