Kéler Béla (13 February 1820, 20 November 1882, Wiesbaden) was a Hungarian composer and conductor. After dropping out of law school, he worked on a farm where he read a textbook by Johann Georg Albrechtsberger and started practicing the violin. By the time he moved to Vienna, he was good enough to play in the theater orchestra. He studied with Simon Sechter and conducted various orchestras, as well as the band for an Austrian military unit. In the 1870s, Kéler toured all over Europe.
