In this paper, I argue that the German morphological tradition made a major contribution to twentieth-century study of form. Several scientists paved the way for this research: paleontologist Adolf Seilacher (1925–2014), entomologist Hermann Weber (1899–1956), and biologist Johann-Gerhard Helmcke (1908–1993) together with architect Frei Otto (1925–2015). All of them sought to examine morphogenetic processes to illustrate their inherent structural properties, thus challenging the neo-Darwinian framework of evolutionary theory. I point out that the German theoretical challenge to adaptationist thinking was possible through an exchange and transfer of practices, data, technologies, and knowledge between biologically oriented students of form and architects, designers, and engineers. This exchange of practices and knowledge was facilitated by the establishment of two collaborative research centers at the beginning of the 1970s. Hence, by showing the richness of topics, methods, and technologies discussed in German-speaking morphology between 1950 and the 1970s, this paper paves the way to a much broader comprehension of the shifts that have shaped twentieth-century evolutionary biology.
