Michael Gottlieb Hansch

Michael Gottlieb Hansch (born September 22, 1683 in Müggenhahl (today Rokitnica ), † 1749 in Vienna ) was a German philosopher , theologian and mathematician .

Life

Hansch, the son of a preacher, studied at the University of Leipzig from 1702 and obtained the academic degree of a master's degree there in 1703. He then studied theology and received his doctorate in theology at the University of Rostock in 1709 . 1710–1711 he lectured at the University of Leipzig. He then lived in Dresden , Prague , Vienna , Frankfurt / Main and Frankfurt (Oder) . In 1718 he was appointed imperial council. He had personal contact with Christian Wolff and Gottfried Wilhelm Leibniz . Until the end of his life he endeavored to spread Leibniz's philosophy and to publish Kepler's collected works.

Half title and title of the volume edited by Hansch from the estate of Kepler, Emperor Karl VI. dedicated.

In Danzig in 1708, Hansch bought the handwritten estate of Johannes Kepler for 100 guilders ; he arranged it in 22 volumes and had the plan to make it accessible to science. In 1718 the first part was a selection of letters from and to Kepler ( Joannis Keppleri aliorumque epistolae mutuae ). This also contained a first short biography of Kepler on pages I-XXXVI. The company soon got stuck in financial difficulties and only Kepler's work on the Gregorian calendar appeared ( De Calendario Gregoriano , translation by Hansch, 1726). In 1721, Hansch was forced to move 18 volumes of Kepler's estate for 828 guilders to Frankfurt due to financial difficulties; the remaining 4 volumes from which he edited the selection of letters went to the imperial court library in Vienna. Hansch could never redeem the estate and died impoverished. Christian von Frisch succeeded for the first time in a scientifically annotated complete edition almost 150 years later .
