Caffeine Google Doodle

"You can thank Friedlieb Ferdinand Runge for making some eye-opening discoveries, including one that's an integral part of our lives 200 years later.
The German analytical chemist began conducting chemical experiments at a young age, identifying the pupil-dilating effects of belladonna when he accidentally splashed a drop of the toxic perennial, also known as deadly nightshade, into his eye.
But a stimulating, 1819 discovery is the reason Google will be celebrating Runge's 225th birthday Friday, February 8 by way of an animated Doodle. For after Runge demonstrated his belladonna discovery to Johann Wolfgang von Goethe, he was encouraged to analyze the chemical makeup of coffee beans, leading a few months later to the identification of caffeine as its active ingredient."
