Charles Auguste de Bériot was a Belgian violinist and composer born on February 20, 1802 (Beethoven was 32 years old.) It is said that his playing was influenced by Viotti, Baillot, and Paganini. He toured Europe extensively and was chamber violinist to King Charles the Tenth of France and King William the First of the Netherlands. In 1843, De Beriot became a professor of violin at the Brussels Conservatory. His best known pupil was Henri Vieuxtemps. He retired from that post in 1852. His compositions are varied and he wrote no less than 10 violin concertos. He is remembered for his violin etude books which are still in use today. De Beriot died in 1870.
