Gustav Mahler (7 July 1860 – 18 May 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. While in his lifetime his status as a conductor was established beyond question, his own music gained wide popularity only after periods of relative neglect which included a ban on its performance in much of Europe during the Nazi era.
