Paul Berthold August Ludewig (born April 15, 1885 in Göttingen , † July 10, 1927 in Freiberg ) was a German physicist.

Life

Ludewig attended elementary school and grammar school in his hometown, where he passed the final exams in 1903. He then studied mathematics and physics at the universities in Göttingen, Munich and Berlin. In 1907 he did his doctorate at the Georg-August-Universität Göttingen , after which he worked as an assistant at the Electrotechnical Institute in Karlsruhe. From 1908 to 1910 he worked as an assistant at the Electrotechnical Institute in Frankfurt am Main and from 1910 to 1911 at the Physics Institute of the University of Göttingen.

On October 1, 1912, he came to the Bergakademie Freiberg , where he initially worked as an assistant at the Institute for Physics and Electrical Engineering. After his habilitation on March 1, 1913, he became a private lecturer in pure and applied physics. In 1914 he signed the declaration of the university lecturers of the German Reich and served as a war volunteer for a short time as a radio operator with the telegraph battalion in Kaditz .

In 1916 he returned to Freiberg. He was appointed associate professor and entrusted with the management of the Institute for Radium Studies. From December 1916 to November 1918 he was given leave of absence from the Bergakademie in order to pursue a voluntary activity as a research assistant at the Torpedo Inspection in Kiel .

In 1921 he organized an international radium congress in Freiberg for the creation of uniform principles for the activity measurements of spring water. In addition to representatives of the Saxon government and the Saxon Mining Authority and the like. a. and Hans Geiger , Otto Hahn and Lise Meitner took part. His proposal to use the Eman as a unit for measuring radioactivity was accepted.

Paul Ludewig worked at the Bergakademie until January 1927. He died on July 10, 1927 after a long and serious illness at the age of 42 in Freiberg.
