Zimmermann’s coffeehouse stood in the Katharinenstraße in Leipzig, near the market square. From 1729 Johann Sebastian Bach led the Collegium Musicum there, an ensemble that Georg Philipp Telemann had founded as a law student in 1702. Its concerts took place every week, all year round, and twice a week during Leipzig’s three trade fairs. The building was destroyed in the air raids on Leipzig in December 1943.
