Today Google devotes its doodle to this scientist who carried out experiments since childhood and came to identify the mydriatic effects of belladonna extract. In 1819 he showed his discovery to Goethe, who proposed to him to analyze the coffee. A few months later, Runge identified caffeine.

Runge studied chemistry in Jena and Berlin, where he obtained a doctorate. After traveling through Europe for three years, he taught chemistry at the University of Breslau until 1831. From then until 1852 he worked for a chemical company, but was fired there and died in poverty fifteen years later.

His chemical work included purine chemistry, caffeine discovery, aniline blue dye, coal tar products, paper chromatography, pyrrole, quinoline, phenol, thymol, and atropine.
