Ludwig Bergmann (physicist)

from Wikipedia, the free encyclopedia

Hans Franz Rudolf Ludwig Bergmann (born February 15, 1898 in Wetzlar , † September 16, 1959 in Heidelberg ) was a German physicist and university professor.

Live and act

Ludwig Bergmann was born the son of a factory owner in Wetzlar. From Easter 1904 to Easter 1907 he attended the municipal lyceum in Wetzlar, then the humanistic grammar school. At Easter 1916 he passed his Abitur in Wetzlar and began studying physics and mathematics at the University of Giessen in the summer semester . From April 1917 to February 15, 1919 he served in the army and then continued his studies in Giessen. In 1921 he was promoted to Dr. rer. nat. doctorate and then assistant at the Physics Institute. From April 1, 1923 to April 1, 1925 he was an engineer at Telefunken in Berlin.

Then he moved to the Physics Institute at the University of Marburg as an assistant , where he received the Venia legendi in physics in 1926 . In 1927 he went to the University of Breslau with Clemens Schaefer . He became an associate professor there in 1932 and was full professor and director of the Physics Institute of the Technical University of Wroclaw from 1939 to 1945 . From 1940 to 1945 he was also an honorary professor at the University of Breslau. In 1949 he became head of the scientific department of the Leitzwerke and in 1950 honorary professor at the University of Giessen.

In addition to his work as a university professor, Bergmann and Schaefer published the multi-volume work Experimentalphysik , which has since been revised several times and is still the Bergmann-Schaefer textbook on experimental physics today as the standard work for physics students. In addition, he is co-author of the work Basic Tasks of the Physics Internship , first published in 1942 , for which the same applies, and of the first monograph on ultrasound , which appeared in 1937 and was translated in the USA and England the following year.

In 1935 he was awarded the Ladenburg Foundation Prize and in 1957 a member of the German Academy of Natural Scientists (Leopoldina) .
