Gideon Klein (6 December 1919 – c. January 1945) was a Czechoslovakian pianist, classical music composer, educator and organizer of cultural life at Theresienstadt concentration camp. Life Klein was born into a Moravian Jewish family in Přerov and, showing musical talent early, studied piano with Růžena Kurzová and Vilém Kurz, and composition with Alois Hába (in 1939–40). He was forced to abort his university studies in 1940 when the Nazis closed all institutions of higher learning following their occupation of Czechoslovakia in March 1939. Since compositions and performances by Jewish musicians were banned, his own works could not be performed, though he managed to perform as a concert pianist under several aliases for a time, e.g., under the pseudonym Karel Vranek. Despite those harsh circumstances Klein managed to continue composing. In 1940 he was offered a scholarship at the Royal Academy of Music in London, but by that time anti-Jewish legislation prevented his emigration. In December 1941 he was deported by the Nazis to Terezín concentration camp, where along with Leoš Janáček's pupil Pavel Haas, Hans Krása, and Schoenberg's pupil Viktor Ullmann he became one of the major composers at that camp. He gave concerts in secret, but the camp became one of the few in which artistic activity was eventually permitted by Nazis on any scale, if only to deceive the broader public as to their real intentions. His works from these years include music for string quartet (similar in tone to Berg's opus 3 work), a string trio, and a piano sonata, among others. Moreover, Klein performed as solo pianist at approximately 15 recitals, and also participated in chamber music performances (member of piano trio, piano quartet). Klein was deported to Auschwitz in October 1944 and then to Fürstengrube, a coal-mining labour camp, in October 1944, less than two weeks after completing his string trio. He died under unclear circumstances during the liquidation of the Fürstengrube camp in January 1945. He had confided his manuscripts to Irma Semtska, his Theresienstadt girlfriend, before leaving, and they were turned over to his sister Eliska at the war's end. His work was influenced by Alois Hába, Arnold Schoenberg, Alban Berg, and particularly Leoš Janáček. He used melody from Janáček's Zápisník zmizelého as a theme in his Divertimento (1940). Klein died at age 25 on January 25,1945 in Fürstengrube, a subcamp of Auschwitz. Recordings on Northeastern and on Koch International Classics, for
