Starting with H. Reichenbach’s work “Relativitätstheorie und Erkenntnis apriori”, Berlin: Springer (1920; JFM 47.0774.02; JFM 50.0688.04) the author traces the professional relationship of H. Reichenbach and H. Weyl in the 1920s following their publications and their written correspondence. Although Reichenbach and Weyl had different philosophical orientations, in particular concerning their views on the physical foundations of Minkowski geometry, their relationship seems to have been good in the beginning. However, as Rynasiewicz shows, it changes significantly with Weyl’s review of “Axiomatik” (Reichenbach, 1924) and Reichenbach’s response to it.
Many original quotes and a short description of the Möbius transformation in \(R^4\) provided by the author help the reader to understand the problem which obviously triggered the falling out between the two scientists.
