Friedrich August Kekule
, Adolphe Wurtz, y Karl Weltzien (1813-1870) convocaron este primer congreso internacional a celebrarse durante los dias 3, 4 y 5 de septiembre de 1860, la forma de organizar un evento de semejante magnitud se ha mantenido hasta nuestros dias.
The 19th-century German chemist Friedrich August Kekule
had spent years studying carbon compounds, trying to deduce their molecular shape.
For example, Louis Pasteur (1822-1895), who initially wanted to be a professor of fine arts, attended lectures by Dumas, who encouraged him to do research in chemistry ; and Friedrich August Kekule
(1829-1896), a pupil of Liebig, in Giessen, went to Paris to follow courses given by Dumas .
However, Frankland's notion of valence (see 1852) offered an important handle, which the German chemist Friedrich August Kekule
von Stradonitz (1829-1896) made use of.
In 1858 Friedrich August Kekule
introduced his valence bond theory of chemical combination that he used in 1865 when he suggested a chemical structure for benzene.
