Abstract
<jats:p>This chapter presents Friedrich Adolf Paneth in the second half of the 1920s as an internationally respected scientist who was repeatedly passed over within the German university system. While his visiting professorship at Cornell University was both professionally and personally successful, several appointment procedures in Germany—including in Karlsruhe, Freiburg, and Jena—came to nothing.</jats:p> <jats:p>The chapter identifies latent antisemitism, nationalist labels, and Paneth’s hard-to-classify profile between inorganic chemistry, physical chemistry, and radiochemistry as central reasons. Temporary research setbacks, especially in the helium experiments, and the rapid transformation of valence theory and quantum theory also played a role. The call to Madison underscored Paneth’s international appeal but initially brought him only a salary increase in Berlin; not until 1929 did he finally receive a chair.</jats:p>
