Johann Ludwig Alefeld (born May 19, 1695 in Grünstadt , † January 20, 1760 in Gießen ) was a German philosopher and physicist.

Life

Johann Ludwig Alefeld was the son of the preacher Georg Alefeld. He had attended grammar school in Worms in 1706 and began studying philosophical and theological sciences at the University of Giessen in May 1713 . Here Johann Christian Lange (1669–1756) was his teacher in logic and metaphysics, Johann Melchior Verdries (1679–1735) in physics and mathematics, Johann Jakob von Wieger (1683–1762) in ethics, Johann Christoph Bielenfeld (1664–1727) , Johann Bartholomäus Rüdiger (1660–1729) and Johann Heinrich May the Elder in theology and with Johann Heinrich May the Younger he learned the Greek language and history. In 1715 he moved to the University of Halle and soon afterwards to the University of Leipzig , where he attended lectures with August Friedrich Müller and Andreas Rüdiger (1673–1731) and decided to study law.

However, it was only an attempt, since he was more and more caught up in the philosophical sciences. In 1717 he acquired the baccalaureate in Leipzig and in February 1718 the philosophical master's degree , with which he began to work as a private lecturer. In 1721 he returned to Gießen via Jena , where he took over the majority of the princely scholarship holders on July 24, 1723 and worked there as a private lecturer. On August 29, 1729, he was given an extraordinary professorship in philosophy and on November 14 of the same year the full professorship in poetry. On November 14, 1737 he switched to the professorship of physics, on June 11, 1748 he became Ephorus of the princely scholarship holders, in 1749 first professor of philosophy and on January 29, 1756, Inspector rerum oeconomicarum.

Two sons and eight daughters are known from his marriage on July 27, 1730 to Helena Klara (* 1713 - March 20, 1774), the daughter of the administrator and bailiff Paul Justus Bodenburg and his wife Magdalene Rosine Katherine Odel. Of these we know: S. Georg Ludwig Alefeld ; T. Marie Luise Elisabeth Alefeld (born April 7, 1736 in Gießen); T. Karoline Helene Alefeld (born January 24, 1738 in Giessen); S.
