He earned his Ph.D. from the University of Leipzig. From 1653 until his death in 1699, he was professor of mathematics at the Jena University. He is noted as the teacher of Leibniz in 1663, and other notable students. He also worked to make science more widely accessible to the public, or, what could be considered today a popularizer of science. Through Leibniz, Weigel is the intellectual forefather of a long tradition of mathematicians that connects a great number of professionals to this day. The Mathematics Genealogy Project lists more than 44.000 "descendants" of Weigel's, including Lagrange, Euler, Poisson and several Fields Medallists. Doctor of Philosophy (Ph. ...
