and three years later he worked with Escher-Wyss of Zurich on refrigeration. In 1894 he became an industrial consultant for refrigeration technology and also received a doctorate from the University of Munich for his work on the thermodynamic limits of cooling. He also founded the journal ''Zeitschrift für die gesamte Kälte-Industrie''. It was unusual at the time for engineers to be able to conduct scientific research. He was appointed a professor of applied physics at Halle in 1896 and in 1900 he succeeded Eugen Meyer as director of the institute for technical physics. He wrote a textbook on mathematical physics which included work on vibrations, oscillations and damping. During this period he also worked on the hydrodynamics and turbines although his mathematical approach was criticized by Richard von Mises. In 1904 he moved to the Technische Hochschule at Danzig, retiring in 1934. Lorenz's work included the mathematics and physics of refrigeration, the strength of materials, vibrations, fluid dynamics, ballistics and even astrophysics.
