Emil Telmányi, b. 22 June 1892 in Arad, then in the Kingdom of Hungary, d. 13 June 1988 in Holte, Denmark was a Hungarian violinist who invented the Bach bow, designed to play and sustain three or four notes on a violin for Bach's sonatas and partitas for solo violin. Telmányi was also an exponent of the composer Carl Nielsen, having recorded some of his violin sonatas and his violin concerto. Telmányi settled in Copenhagen and was married to Nielsen's daughter, Anne Marie, from 1918 to 1933. One of his most famous recordings is a 1954 recording of Bach's solo violin sonatas and partitas played using a violin with what was referred to as the Bach (or Vega) bow, which could be adjusted so the player could play three or even all four strings of the violin at once.
