Johannes WislicenusDied 5 Dec 1902 at age 67 (born 24 Jun 1835). Johannes Adolph Wislicenus was a German chemist whose pioneering work led to the recognition of the importance of the spatial arrangement of atoms within a molecule. He is noted for his work on the lactic acids, and in particular for his discoveries in the study of the geometrical isomerism (the existence of identical formulae with differing chemical properties) of organic compounds. |
