Kekulé: The Beautiful Dreamer
Friedrich Kekulé, a German chemist, was working on the structural formula of benzene, C6H6, in the mid-1860s. Late one night, he was sitting in his apartment in front of a fire. He began dozing off and, in the process, saw groups of atoms dancing in the flames like snakes. Then, suddenly, one of the snakes reached around and made a circle, or a ring.
This vision startled Kekulé to full consciousness, and he realized that benzene had a ring structure. Kekulé’s model for benzene paved the way for the modern study of aromatic compounds.
