Jascha Horenstein (1898-1973) was born in Kiev but studied in Vienna. After a move to Berlin, he became Wilhelm Furtwangler's assistant and during the 1920s he conducted both the Vienna Symphony Orchestra and the Berlin Philharmonic. At this time, he came into contact with Schoenberg, Stravinsky and Nielsen. In 1929, Horenstein became the music director of the Dusseldorf Opera but, with the outset of war, he settled in the US. He conducted some of the major orchestras there but returned to Europe in 1947, where he was much in demand including a close association with the LSO. He is best remembered for his outstanding Mahler and Bruckner performances but, being Russian, he conducted Shostakovich who he knew, and because of his early links with Nielsen, both composers were featured throughout his life.
