Mahler
Gustav Mahler (1860-1911) was an Austrian late-Romantic composer, and one of the leading conductors of his generation. As a composer he acted as a bridge between the 19th century Austro-German tradition and the modernism of the early 20th century. The premier of the First Symphony, in Budapest on 21 November 1889, was a disappointment. The critic August Beer's lengthy newspaper review indicates that enthusiasm after the early movements degenerated into "audible opposition" after the Finale. Mahler was particularly distressed by the negative comments from his Vienna Conservatory contemporary, Viktor von Herzfeld, who had remarked that Mahler, like many conductors before him, had proved not to be a composer.
