Johann Gottlob Immanuel Breitkopf
Johann Gottlob Immanuel Breitkopf (Leipzig, 23 November 1719 – 28 January 1794, Leipzig) was a German music publisher and typographer.
Breitkopf was the son of the publisher Bernhard Christoph Breitkopf, founder of the publishing house Breitkopf & Härtel. He was born in Leipzig and attended the University of Leipzig. His investigations in history and mathematics led him to a scientific study of printing, which resulted in a more artistic development of German text, and an improvement of musical notation (1754). He revolutionized the music score printing with movable types, and fonts designed as Breitkopf Fraktur.
