A late-Romantic composer who occasionally worked in a more modern style, Alexander Zemlinsky (October 14, 1871 – March 15, 1942) was something of a prodigy. Anton Bruckner was among his teachers. Brahms, impressed by the Symphony in D and a quartet, recommended Zemlinsky to Simrock, Brahms's publisher and arranged a stipend for the young composer. Zemlinsky was friends with the slightly younger Arnold Schoenberg and taught him counterpoint (in which Brahms had tutored Zemlinsky); Schoenberg later married Zemlinsky's sister.
The connection to Schoenberg (who studied music with no-one else) probably contributed to the revival of Zemlinsky's music, which was largely forgotten in the decades after the Nazis drove the Jewish composer first from Germany back to his native Vienna, and then to America, where he found none of the success Schoenberg achieved in exile.
