Friedlieb Ferdinand Runge (8 February 1794 – 25 March 1867) was a German analytical chemist. Runge identified the mydriatic (pupil dilating) effects of belladonna (deadly nightshade) extract, identified caffeine, and discovered the first coal tar dye (aniline blue).
Albert Friedrich Emil Niemann (May 20, 1834 – January 19, 1861) was a German chemist. In 1859 — about the same time as Paolo Mantegazza — he isolated cocaine , and he published his finding in 1860.

In 1895, German chemist Hermann Emil Fischer (1852–1919) first synthesized caffeine from its chemical components (i.e. a "total synthesis"), and two years later, he also derived ...
