Hubert Léonard (7 April 1819 – 6 May 1890) was a famous Belgian violinist, born at Bellaire, Liège. His earliest preparatory training was given by Rouma, after which he entered the Paris Conservatory in 1836, where he studied for three years under Habeneck. In 1844 he started his extended tours which established his reputation as one of the greatest of virtuosos.
From 1848 to 1867 he held the position of principal professor of violin playing at the Conservatory of Brussels, having succeeded the celebrated de Bériot. Owing to ill health, he resigned and settled in Paris where he taught private lessons. Among his notable students are Alfred De Sève, Martin Pierre Marsick, Henri Marteau, Henry Schradieck, and César Thomson. He wrote a notably instructive work titled Ecole Léonard. Léonard died in Paris in 1890.
