Friedrich+August+Von+Stradonitz+Kekulé

Friedrich August Kekule was a german scientist born on september 7, 1829. He earned a degree form the University of Giessen.
==Kekulé's idea of assigning certain atoms to certain positions wit the molecule, and connecting them using what he called their "Verwandtschaftseinheiten" or "bonds", was based largely on evidence from chemical reactions, rather than on instrumental methods that could peer directly into the molecule. Such physical methods of structural determination had not yet been developed. Some chemists, heavily criticized the use of structural formulas that were offered, as he thought, without proof. However, most chemists followed Kekulé's lead in pursuing and developing what some have called "classical" structure theory, which was modified after the discovery of electrons and the development of quantum mechanics. ==
