Photogravure after a photograph by Nicola Perscheid. Among van't Hoff's (1852-1911) achievements were the discovery of the laws of chemical dynamics and osmotic presure in solutions. In 1878 he was appointed to the Amsterdam chair of chemistry, moving to the University of Berlin in 1896. He created a new branch of science, known as stereochemistry, and discovered optically active compounds. Van't Hoff's research into the structure of the carbon atom, recently established by Kekule, led him to an explanation of molecular asymmetry. He won the first Nobel Prize in Chemistry 1901. From a collection of portraits of scientists published by Photographische Gesellschaft, Berlin, c 1910. Dimensions: 460 mm x 340 mm.
