Abstract
In 1949, Philipp Frank claimed that he and Rudolf Carnap built up a new center for the scientific world conception in Prague between 1931 and 1935. The aim of this paper is to provide historical evidence and further materials to approach this claim of Frank. Definite answers, however, require more space and contextualization, so I will just sketch some partial but hopefully promising narratives and rudimentary answers. I claim that though Carnap and Frank indeed tried to build a new center, they were unsuccessful, and possibly there were many reasons for this. This is the general claim; regarding Carnap, I will also show his way to the German University of Prague and his philosophical, scholarly, and cultural life in Prague.
