1870 | Louis A. Kahlenberg was born. He studied solutions, dialysis, gas electrodes, and the activation of gases by metals; investigated potentiometric titrations, boric acid in the treatment of blood poisoning, the use of colloidal gold in treatment of malignancies, and the use of dichloroaceticacid in medicine; his criticisms of Arrhenius' theory of ionization led to Debye's and Hückel's modifictions of the theory to account for the electrical interactions of the ions. |
1865 | F. August Kekulé presented his benzene structure to Société Chimique, Paris. |
