a famous woodwind instrument maker of the Baroque era, to whom the invention of the clarinet is attributed. Denner was born in Leipzig to a family of horn-tuners. With his father, Heinrich Denner, a maker of game whistles and hunting horns, he moved to Nuremberg in 1666. J. C. Denner went into business as an instrument maker in 1678 and was granted rights for the 'manufacture of French musical instruments consisting chiefly of oboes and recorders [flandadois]' in 1697. Two of his sons, Jacob and Johann David, also became instrument builders.
