Gottfried Heinsius

Gottfried Heinsius (* April 27, 1709 in Naumburg ( Saale), † May 25 1769 in Leipzig ) was a German mathematician, geographer and astronomer.

Life

At the University of Leipzig Heinsius started after reaching the higher education a study of philosophical sciences, where he developed a taste for astronomical research at Christian August Hausen ( 1693-1743 ). In 1733 he earned the degree of Master of Arts and habilitated in 1734 as Master legens at the Faculty of Philosophy. During that time, he got into a dispute with Taught Friedrich Wilhelm Stübner (1710-1736), who represented the opinion of Gottfried Wilhelm Leibniz and the Heinsius of René Descartes.

After the dispute was settled in 1735, was Heinsius in 1736 as associate professor of astronomy at the University of St. Petersburg and was associated with it an adjunct of the first professor of astronomy Joseph Nicolas de l' Isle ( born April 4, 1688 in Paris, † September 12 1768). After a long vacancy of the Wittenberg professor by the death of Johann Matthias Hase had been proposed in 1742 Heinsius. However, because there were delays in the introduction to this office in Wittenberg, Elector of Saxony directed him after the death of Stockhausen at the Leipzig Academy.

In Leipzig he was still seven years as professor of mathematics, where he continued employed in addition to his lectures with his research on geography and astronomy. His essays treated geographical remarks on Yakutia, and Leipzig, methods of producing gold colors, as well as its results of the moon, sun and Saturn observations. He was a member of the Academy of Sciences in St. Petersburg since 1744. In addition, Heinsius also participated in the organizational tasks of the Leipzig Academy and was in the winter semester rector of the Alma Mater.

According to him, named the crater on the moon Heinsius.
