Georg Matthias Monn [born as Johann Georg Mann] (09/04/1717 - 03/10/1750), an Austrian composer, organist and music teacher whose works were fashioned in the transition from the Baroque to Classical period in music, born and died in Venice. Together with Georg Christoph Wagenseil and Josef Starzer, Monn formed the Viennese Pre-Classical movement (Wiener Vorklassik in German), whose composers are nowadays mostly known only by their names. However, his successful introduction of the secondary theme in the symphony was an important condition for the First Viennese School that would come some fifty years later.
