Philipp Matthäus Hahn (1739 - + 1790)
Hahn was born on 25 November 1739 as the eldest son of a protestant pastor in the South German town Scharnhausen auf den Fildern (a small town 5 kilometers from Esslingen and 15 kilometers from Stuttgart). At home the young Philipp already received lessons in reading, writing and mathematics as well as Latin, Greek and Hebrew. At the age of twelve Philipp Matthäus attended the Lateinschule in Esslingen, followed in 1752 by a short intermezzo in one of the Württenbergische monastic schools, where he failed to pass the exams. Instead he went to a religious preparation school Vorbereitungsschule für die niedrige Geistlichkeit in Nürtingen. In this period he already developed his broad interest in science.
From 1756 onwards he studied theology at Tübingen University. In 1759 he graduated at the age of twenty, in this period Hahn was not only specialized in theology, but also wrote articles on science, astronomy, chemistry and alchemy. His first designs for microscopes, telescopes, his calculator and off course clocks are dating from this period. From 1760 to 1765 he worked as a private teacher in Lorch and as a curate in Breitenholz, Herrenberg, Tieringen and Pfäffingen.
In 1770 Hahn was appointed as pastor in Onstmettingen, succeeding his father.
In Onstmettingen his first instruments, calculators and clocks were built. A small workshop developed and his famous calculator was build there amongst some complicated astronomical clocks. In this period he also attracted the attention of the German courts of Kaiser Josef II, the Duke Carl August of Sachsen-Weimar and Duke Carl Eugen von Württemberg, who entitled Hahn as the 'divine clockmaker' Uhrmacher Gottes.
Under the influence of Duke Carl Eugen, Hahn moved to Kornwestheim around 1780.
Hahn settled himself and his family in Kornwestheim, and it was there he built a large and proper workshop and his production of highly complicated movements and instruments flourished.
It is here to mention that next to the activity as a clockmaker and instrument maker Hahn still worked as pastor in Echterdingen, he published a lot of theological treatises and published various works on clocks, science and astronomy. Hahn finally established two workshops, one in Kornwestheim and one in Echterdingen which also enabled his brothers and sons to work as clockmakers and mechanics.
Around this time Hahn was settled as a famous and well-known pastor, astronomer, mechanic and clockmaker and was established within the courts and nobility through his complicated clocks and astronomical inventions, and within the higher-class through his pocket watches, calculators and scales.
These widespread relationships included close ties to the court of Duke Carl Eugen von Württemberg. The relationship and protection of the Duke enabled Hahn to withstand the pressure of the ecclesial government and gave him the opportunities to focus on his clock making and his technical, scientific and astronomical interest, next to the theological challenges and questions.
Philipp Matthäus Hahn died on 2nd of May 1790 in Echterdingen, leaving an important heritage of highly skilled and complicated scientific instruments and clocks.
Johannes Klinckerfuß (1770- + 1831)
Johannes Klinckerfuß was one of the most important German cabinet makers of the early 19th century. After his apprenticeship he started in 1789 in the workshop of David Roentgen in Neuwied. He soon became famous for his craftsmanship and creative flair, and was recommended by Roentgen to the Bayreuther Hof of Herzog Friedrich Eugen von Württemberg, where he was in charge of the furnishing of Schloss Fantaisie. From 1795 onwards Klinckerfuß worked in the herzogliche Kabinettschreinerei for the Stuttgarter Hof, where he became cabinet-ebenist for Duke Frederick II of Württemberg, later the first king of Württemberg. In 1812 Klinckerfuß opened his own workshop in Stuttgart. He made numerous important pieces in the Empire style. Many of these still remain in the castles Weil near Esslingen, Ludwigsburg and Rosenstein.
