Johann Friedrich Weidler

Johann Friedrich Weidler ( born April 23 1691 Großneuhausen, † December 30, 1755 in Wittenberg ) was a German mathematician and legal scholars.

Life

With fifteen years Weidler entered the University of Jena, matriculated at June 10, 1712 at the University of Wittenberg, obtained on April 30, 1712 the degree of Master of Arts and was on April 19, 1715 Adjunct to the philosophical faculty of the Wittenberg Academy. After they had in 1715 conferred on him the professorship of the lower mathematics, he took over in 1719 the chair of higher mathematics.

1726 and 1727 he interrupted his teaching to undertake a journey to Holland, England, France and Switzerland. In Basel, he became in 1727 a doctorate in Basel as a doctor of the law. He returned to Wittenberg and became an extraordinary professor at the law school. Yet was his academic work, the mathematical discipline. Then, as he feared, be reamed in both disciplines, he devoted all his energies to the natural sciences.

Of the compendia, which he wrote as a foundation of his lectures, found the " Institutiones mathematicae " which included the astronomy so much attention that they have been reissued five times to Weidlers lifetimes and still had more editions after his death. With the " Institutiones subterraneae " Weidler created the first scientific compendium of mining Mine art.

But his greatest work was the story of his favorite compartment, astronomy, containing an abundance of biographical and bibliographical data and is considered very reliable. He also wrote a description of the Mercury passes through the sun of 1736 and 1747 and a calculation of the length and width of Wittenberg, about what work surprised him death. After he had passed several times the Dean of the Faculty of Arts at Wittenberg, he took over in the summer semester 1724 and 1744 the Rector of the University of Wittenberg.
