Leopold Antonín Koželuh (Kozeluch, Kotzeluch) (1747-1818), was born in Bohemia (today Czech Republic). He was baptized Jan Antonín, but early on in life changed his first name to avoid confusion with an older cousin (one of his teachers).
Koželuh spent most of his life as a successful musician and composer in the Vienna of Haydn and Mozart. He became so well established that he could afford to refuse an offer from the Archbishop of Salzburg to succeed Mozart as organist.
Koželuh’s list of works is dominated by piano and chamber music, but also includes songs, 22 piano concertos, 11 symphonies, and a Sinfonia concertante for mandolin, trumpet, double bass, piano and orchestra.
