Berlioz

Hector Berlioz (French: [ɛktɔʁ bɛʁljoːz] (English: /ˈbɛərlioʊz/); 11 December 1803 – 8 March 1869) was a French Romantic composer, best known for his compositions Symphonie fantastique and Grande messe des morts (Requiem). Berlioz made significant contributions to the modern orchestra with his Treatise on Instrumentation. He specified huge orchestral forces for some of his works, and conducted several concerts with more than 1,000 musicians. He also composed around 50 songs. His influence was critical for the further development of Romanticism, especially in composers like Richard Wagner, Nikolai Rimsky-Korsakov, Franz Liszt, Richard Strauss, and Gustav Mahler.

Hector Berlioz was born in France at La Côte-Saint-André in the département of Isère, near Grenoble. His father, Louis Berlioz, a respected provincial physician and scholar who is widely credited for first experimenting with and recording the use of acupuncture in Europe, was responsible for much of the young Berlioz's education. Louis was an agnostic, with a liberal outlook; his mother, Marie-Antoinette, was a devout Roman Catholic. He had five siblings in all, three of whom did not survive to adulthood. The other two, Nanci and Adèle, remained close to Berlioz throughout his life.
