	Friedrich August Kekulé von Stradonitz - Wikipedia, the free encyclopedia
		Friedrich August Kekulé von Stradonitz (September 7, 1829 – July 13, 1896) was a German organic chemist.
		In 1857 Kekulé proposed that carbon was tetravalent.
		In 1895 Kekulé was ennobled by Emperor William II, giving him the right to add "von Stradonitz" to his name, referring to an ancient possession of his family in Stradonice, Bohemia.

		Friedrich August Kekulé was born on September 7, 1829 in Darmstadt, Germany.
		Kekulé's oscillation theory of rapidly interchanging double bonds in the benzene ring explained the existence of only one disubstituted derivative in various syntheses--a problem that his earlier conception of the ring structure of benzene did not address.
		Kekulé Charicature- donated by William Jensen, University of Cincinnati, and may be used for educational purposes only.

	Aromaticity (Site not responding. Last check: 2007-09-19)
		The model for benzene consists of two resonance forms, which corresponds to the double and single bonds switching positions.
		The circulating pi electrons in an aromatic molecule generate significant local magnetic fields that can be detected by NMR techniques.
		Aromaticity was discovered by Kekul� in benzene, and was first explained in quantum mechanical terms by Linus Pauling in the 1930s.

		von Stradonitz, Friedrich (1829-1896) German chemist who introduced the concept of the chemical bonds, the tetravalent carbon atom, and the use of structural formulas to explain the formation of molecules.
		He proposed a structure for benzene consisting of a ring of carbon atoms with alternating double and single bonds.
		He thought the application of atomism was useful to explain the chemical properties of compounds, but also believed in the actual existence of atoms.

		Friedrich August Kekul (von Stradonitz) (1829-1896) was one of the principal chemists of the 19C.
		In this way began the structure theory." Kekul's vision and notation helped lead to the present chemical notation within a decade.
		He is even more famous for a later dream, gazing into a fire in Ghent, Belgium, in 1865, when he visualized the hexagonal ring structure of benzene, described as 'the most brilliant piece of prediction in organic chemistry'.
