Alfred Ehmert

from Wikipedia, the free encyclopedia

Alfred Ehmert (born March 6, 1910 in Crailsheim , † February 13, 1971 in Lindau ) was a German physicist who worked as director at the Max Planck Institute for Aeronomy and researched the phenomenology of cosmic rays .

Life

Alfred Ehmert studied after visiting the school in Crailsheim and the secondary school in Aalen 1929 Technical Physics at the Technical University of Stuttgart and was at Erich Regener for Doctor of Engineering PhD , who as fellows of the German Research Foundation with the line of the old in him in 1936 The kite station of the weather service commissioned the soil sea laboratory of the Physics Institute of the Technical University of Stuttgart in Friedrichshafen , which at that time served as a base for the measurement of cosmic radiation with submersible devices at different depths of Lake Constance .

On January 1, 1938, he and 2 other scholarship holders moved to the private research center for physics of the stratosphere founded by Erich Regener in Friedrichshafen on Lake Constance , which was incorporated into the Kaiser Wilhelm Society on May 30, 1938 . After the institute was destroyed in an Allied air raid in 1944, the research team continued their research work in a provisional facility in Weißenau near Ravensburg , from which the Max Planck Institute for Stratosphere Physics emerged in 1952. Alfred Ehmert completed his habilitation in physics at the Technical University of Stuttgart from Weißenau and was appointed Scientific Member of the Max Planck Institute for the Physics of the Stratosphere in 1951. In 1954 he was appointed associate professor for physics at the Technical University of Stuttgart and after the transfer of the institute to Lindau am Harz in 1959 under Julius Bartels , he was appointed associate professor for geophysics at the Georg August University in Göttingen .

In 1965, Alfred Ehmert was appointed to the collegial management of the Institute for Stratospheric Physics and was appointed Director at the Max Planck Institute for Aeronomy.

Research into cosmic rays was the main research focus of Alfred Ehmert. In later years he also dealt extensively with studies of atmospheric ozone , the propagation of electromagnetic longitudinal waves in the earth-ionosphere waveguide and with problems of the magnetosphere . With his colleagues he developed the most precise ground device for the electrochemical determination of ozone at the time.

Alfred Ehmert had been a member of the German Physical Society since 1935 , was elected a member of the German Academy of Natural Scientists Leopoldina in the Geophysics and Meteorology Section in 1960 and was a founding member of the International Astronautical Academy.

Several letters from and to the physicist Werner Heisenberg have survived from his correspondence .
