Catalogue Note

The brothers Hahn: Christoph Matthäus (1767-1833), Johann Georg (c.1772-c.1813), Christian Gottfried (1769) and Immanuel (1773-1833) worked for their father Matthäus Hahn (1739-1790). An important figure in the history of German horology, Matthäus Hahn, who was also a clergyman, pioneered the use of the cylinder escapement in Germany and was renowned for his astronomical and calendar clocks. Highly influential, he had many pupils including Jacob Auch. Matthäus' sons Christian and Christoph became "hofmechanikus" - court mechanicians.
