Viennese composer, student of Alexander von Zemlinsky and Robert Fuchs. He won the Beethoven prize for his 3rd string quartet and was Mahler’s assistant at the Vienna Opera. His works were performed by the most emminent artists of the day, and printed by Universal Edition. With the rise of the National Socialists, Weigl, a jew, was forced to leave. Performances were banned and his works dropped from his publishers. Weigl emigrated, taught at the Hart School of Music, Brooklyn College, Boston Conservatory, and the Philadelphia Academy. He completed many works in America, including 3 quartets and 2 symphonies, most of which were not performed. Leopold Stokowski gave the premiere of Weigl’s 5th symphony, the "Apocalyptic", at Carnegie Hall in 1968, nearly twenty years after Weigl’s death.
