(Died: January 25, 1960)
Professor of Physics
Gehrcke in 1920 became head of the Physikalisch-Technische Reich Institute of Charlottenburg in 1921 and professor of physics at the University of Berlin. Gehrcke successfully studied the optical interference phenomena. Besides James O. Reichenheim, he discovered the so-called anodstr?larna. His senior studies focused on atomic physics and relativity theory problems. Among Gehrcke's writings include Die Strahl der positive Elektrizit?t (1909), Theory der Atomkerne (1920), Physik und Erkenntnisstheorie (1921). - Swedish Wikipedia
The Max Planck Institute for the History of Science has recently acquired what has been preserved of the Ernst Gehrcke Papers. Parts of these papers will be digitized and made accessible.
From 1902 until 1946, Gehrcke, an experimentalist and specialist in optics, was employed at the Physikalisch-Technische Reichsanstalt, and became director of the department of optics in 1926. Ernst Gehrcke is known as a fervent critic of Einstein and a leading figure among Einstein's German opponents. The Ernst Gehrcke Papers contain correspondence with the physicists Philipp Lenard, Stjepan Mohorovicic, Ludwig Glaser, Hermann Fricke, Johannes Stark, Otto Lummer and the philosophers Oskar Kraus, Melchior Palagyi, Leonore Frobenius-K?hn, and others; numerous offprints and booklets; some drafts and manuscripts by Gehrcke, for example, ?ber das Uhrenparadoxon in der Relativit?tstheorie and Die erkenntnistheoretischen Grundlagen der verschiedenen physikalischen Relativit?tstheorien, and all the parts which were rescued from the Gehrcke newspaper article collection. - http://echo.mpiwg-berlin.mpg.de/content/modernphysics
