Richard Georg Strauss (11 June 1864 - 8 September 1949) was a leading German composer of the late Romantic and early modern eras. He is known particularly for his operas, Lieder, and tone poems. Strauss, along with Gustav Mahler, represents the extraordinary late flowering of German Romanticism after Richard Wagner, in which pioneering subtleties of orchestration are combined with an advanced harmonic style. Strauss's music had a profound influence on the development of music in the twentieth century. Strauss was also a prominent conductor.
