Ferdinand Trendelenburg

from Wikipedia, the free encyclopedia

Ferdinand Carl Adolph Trendelenburg (born June 25, 1896 in Leipzig , † November 19, 1973 in Erlangen ) was a German physicist . He was one of the pioneers of electroacoustics . From 1958 to 1959 he was President of the German Physical Society .

Life

Trendelenburg was born as the son of the renowned Leipzig surgeon Friedrich Trendelenburg , the last personal physician of the Saxon King Friedrich August III. born. He was the youngest of six brothers, including Wilhelm Trendelenburg , Friedrich Trendelenburg , Ernst Trendelenburg and Paul Trendelenburg . He studied at the humanistic Thomas School in Leipzig and graduated from high school there. In 1914 he began studying physics and mathematics at the University of Edinburgh . During the First World War he served in an artillery regiment in Baden , most recently as an officer on the Western Front .

In 1919 he continued his studies at the Friedrich-Wilhelms-Universität Berlin and at the Eberhard Karls Universität Tübingen . It was 1922 when Max Reich at the Georg-August University of Göttingen with a thesis on The operation of the thermal Phones for Dr. phil. PhD. In 1929 he completed his habilitation in Berlin and became a private lecturer. In 1935 he became associate professor and in 1940 honorary professor of physics. As a young scientist he took part in the famous Laue colloquium at the Physics Institute in Berlin. In 1949 he became an honorary professor for physics at the University of Freiburg and from 1957 for electrical measurement methods in physics at the Technical University of Munich .

His main job was at Siemens AG until his retirement in 1962 . In 1933 he became scientific director of the research laboratory of Siemens & Halske works in Berlin-Siemensstadt .

From February 1940 he was chief of staff at the Working Group Cornelius (AGC), which dealt with the control of torpedoes for the War Ministry. His employees included Ernst-August Cornelius , Walther Gerlach , Abraham Esau , Otto Kraemer and Karl Küpfmüller . From 1949 to 1950 he was employed at the Laboratoire de recherches balistiques et aéro-dynamiques in Weil am Rhein.

After the Second World War, he set up the general laboratory of Siemens-Schuckertwerke in Erlangen. He headed this from 1950 onwards with the rank of director and general representative. In 1958/59 he was President of the German Physical Society and from 1959 to 1969 a member of the Senate of the Max Planck Society . From 1966 he was acting head of the Siemens archive in Munich.

Trendelenburg was co-editor of the journal Results of the Exact Natural Sciences .

family

One of his children was the physicist Ernst Adolf Trendelenburg (1923–1989).

research

In addition to research in acoustics, for which he developed electroacoustic measurement methods, examined questions of sound transmission and sound analysis and which he u. a. also applied in cardiology , he also dealt with many other areas of applied physics such as structural studies with electron diffraction in materials technology.
