Mohl, Hugo von

Abstract

Hugo von Mohl (1805–1872) – German botanist and microscopist – was one of the central figures in the emerging fields of plant anatomy and physiology. His most famous contributions concerned the plant cell, in particular the cell wall and cell division, and the origin of plant vessels from cells. These studies paved the way for cell theory. Moreover, he greatly engaged in the transformation of botany into an inductive science and promoted its institutional autonomy from medicine as well as from philosophy, co‐founding in Tübingen Germany's first faculty of natural sciences.

Keywords: history of botany; cytology; cell wall; cytokinesis; microscopy; osmosis

Figure 2. Mohl's observation of cell division in the algae Conferva glomerata. The cell first grows out of the main stem (1a), lengthens (1b) and finally separates through the formation of a septum (1c). The process of division starts with a slight circular tightening of the membrane (3a). The constriction proceeds (4a, 12a, 14a, 15a, 9c–d) until the complete separation into two cells (5d, 10d).
