The Moravian-born Jewish composer Gideon Klein (1919-45) composed his final work, the String Trio (1944) while interned in Theresienstadt. + Quite a few of his works written there are based on Czech folksongs; his string trio falls into this category. + Jewish composer Josef Koffler (1896-1944) suffered a similarly tragic fate as Klein. + His Trio, op. 10 (1928) was written, however, when he was Prof. of Harmony and Atonal Composition in Lviv (Lemberg). + The Trio in D Major by Ernst Neumann (1832-1910) is a work from 1883. + The Eos Trio Frankfurt is keen to bring forgotten or unknown works back to audiences.
