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 1939-1940).
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. 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, one of the few in which artistic activity occurred on any scale.
Klein was deported to Auschwitz and then to Fürstengrube 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.
His work was influenced by Alois Hába, Alban Berg, and particularly Leoš Janáček. He used melody from Janáček"s Zápisník zmizelého as a theme in his Divertimento (1940).
Recordings on Northeastern and on Koch International Classics, for example, have allowed modern listeners to evaluate the quality of his compositions of the 1940s.
Madrigal for Two Sopranos, Alto, Tenor and Bass to words by Franz Holderlin, Czechoslovakian translation by Erich A (1943) 3" Partita (Trio for Violin, Viola and Cello in arrangement for chamber orchestra by Vojtěch ).
Moreover, Klein performed as solo pianist at approximately 15 recitals, and also participated in chamber music performances (member of piano trio, piano quartet).
