Leo Weiner was one of the most important Hungarian music educators in the first half of the 20th century and a talented but almost unknown composer who created many popular works, mostly chamber and piano music. He studied music at the Landesakademie School of Arts in Budapest in 1901, where he studied with Janos Koessler. Like other Hungarian composers, he was very interested in Hungarian folk music. Working as a répétiteur, he won a prize that allowed him to study music in Vienna, Munich, Berlin and finally Paris. In 1908, he returned to the Landesakademie as a teacher. He remained a faculty member there for his entire life, was appointed professor of composition in 1912, and professor of chamber music in 1920 until 1949.
