Georg Thegen

Georg Thegen (born January 8, 1651 in Königsberg (Prussia) , † January 16, 1729 there ) was a German philosopher and mathematician.

Life

Georg was the son of the businessman Johann Thegen and his wife Dorothea, daughter of the secretary and pronotary Georg Stephani. He had initially attended the old town school in his hometown and received private tuition from an informator. In 1668, under the rectorate of the history professor Jacob Tyder, he moved to the University of Königsberg to study the philosophical sciences. Here he attended the lectures of Besselio, Landenberg, Andreas Concius (also Cuncius, 1628–1682), Rücker, Bartholomäus Goldbach (1640–1708), Vogt and Georg Wosegin (1624–1705).

In 1673 he embarked on a journey that took him via Danzig and Stettin to the University of Greifswald . Here he attended the lectures of Johannes Michaelis (1612–1674), Abraham Battus (1606–1674), Matthaeus Tabbert (1625–1675) and Albert Vogt (1634–1676). He continued his studies at the University of Rostock , where Franz Wolff (1644–1710), August Varenius (1620–1684) and Heinrich Müller were his teachers. On November 12, 1674, he earned a master's degree in philosophy and was allowed to give lectures on mathematics, philosophy, geography, and history.

After lecturing in Rostock for almost two years, he thought of returning to his hometown. However, he still wanted to see the Hanseatic cities of Wismar , Lübeck and Hamburg . He also visited the Saxon academies in Jena , Leipzig and Wittenberg . In 1676 he returned to his birthplace, where he was appointed to the philosophy faculty of the Königsberg University on June 18 by the then dean Andreas Hodio. In 1679 he had received a call as a deacon at the Old Town Church, which he refused.

He wanted to focus more on an academic career. In the same year, on August 29, he took over the full professorship in practical philosophy, which he held until his fiftieth year. The academy's senior retired shortly before the end of his life. During his time as a university lecturer, he also took part in the organizational tasks of the Königsberg University and took over the rectorate of the Alma Mater five times in 1694, 1702, 1710, 1718 and 1726 .

Thegen had married Anna Dorothea Hellwig on February 28, 1686. She was the daughter of the court relative of the old town Jakob Hellwig (* January 24, 1635 - June 13, 1686) and his wife Anna (* December 13, 1648 - February 18, 1681), daughter of the mayor of the old town Daniel Kenckel.
