Martin Knorre

Martin Knorre , also: Knorr, Knorrus (born September 4, 1657 in Halle (Saale) , † March 23, 1699 in Leipzig ), was a German mathematician .

Life

Martin came from the widely ramified Halle scholar family Knorre. He attended high school in Halle, where he developed a penchant for mathematics and theology. In the summer semester of 1670 he enrolled at the University of Leipzig . In 1678 he moved to the University of Jena , where he attended Erhard Weigel's mathematics lectures . After he had acquired the academic degree of a master's degree in philosophical sciences in Leipzig on January 31, 1684, he moved to the University of Altdorf in 1685 , where he conducted mathematical studies with Johann Christoph Sturm . He advised Knorre to take a position as a high school teacher in Riga. However, this endeavor failed. Instead, Knorre continued his studies on March 21, 1686 at the Dutch University of Leiden , where he attended the lectures on experimental physics with Burchard de Volder and those on mathematics with Wolferdus Senguerdius .

On his return to Leipzig he held private lectures on mathematics and physics as an electoral scholarship holder. It was in this context that his treatise on quadratic equations De quadratica aequatione was written on November 24, 1688 . In the same year, at Sturm's instigation, Knorr was appointed to the mathematics chair at the University of Tübingen. At the University of Wittenberg , too, attention had been drawn to the electoral scholarship holder and he was offered the chair of lower mathematics, which he assumed on March 4, 1689 with the inaugural lecture Lectori Benevolo S. & OD (Wittenberg 1689). During his apprenticeship he was in contact with various representatives of the mathematical branch of science, for example with Ehrenfried Walther von Tschirnhaus .

He dealt with the grinding and polishing of optical glasses, was dean of the philosophical faculty and employee at the Acta Eruditorum in 1695 . Knorre also occasionally appears as a companion in the academic work of his students. The works Recensio Amoenitatum Mathematicarum (Wittenberg 1692) and De astronomiae novis inventis (Wittenberg 1695) come from his pen . On July 9, 1694, Knorr married Dorothea Rosina Schubart, the daughter of a Wittenberg merchant. She died on January 15, 1699 giving birth to a daughter. When he wanted to hand over his daughter to his mother-in-law in Leipzig for care, he died himself. He was buried on March 28th of that year in Leipzig.
