Viktor Ullmann studied composition with Schoenberg in Vienna, probably from 1918 to 1921. Later, he became the conductor of the New German Theatre in Prague, and then Director of the Aussig Opera in 1927. He met Alois Habá, a fellow adherent of the Steiner “anthroposophic” movement, with whom he studied quarter-tonal composition at the Prague Conservatory (1935-1937). He lived in Prague until his arrest in 1942. Deported to Terezin, and later transferred to Auschwitz on 16 October, 1944, he was executed upon arrival. His catalogue, self-published during his lifetime, comprises three operas: Peer Gynt based on Ibsen, Der Sturz des Antichrists (libretto by Albert Steffen), and Der Kaiser von Atlantis, oder die Tod-Werweigerung (1943); works for orchestra: Five Variations on a Theme by A. Schoenberg, Concerto for Orchestra, Piano Concerto, Don Quixote Overture; chamber works, including three string quartets, an octet, and several sonatas (one of which is for quarter-tone clarinet, an instrument that was built at the behest of Alois Habá for the Prague Conservatory); and numerous settings of texts by Rilke, Trakl, Steffens, Hölderlin, Wedekind, etc.
