August Kekule transformed the entire field of organic chemistry by unlocking the mystery of molecular structure. Kekule had pondered the mystery of chemical structure for many years, and in 1865, he was concentrating on the unknown structure of the organic compound Benzene.

The Benzene ring became the most important template for the whole science of chemical compounds, even to this very day. For 25 years, Kekule kept secret the scientific method which had enabled this historic discovery. But at a conference in 1890, he finally revealed the story behind the discovery.
