Friedlieb Ferdinand Runge was born on 8 February 1794. In his career as an analytical chemist, he is famous for identifying caffeine and belladonna. My tie shows steaming cups of coffee! I'm holding Beth's chemis-tree ornament of the caffeine molecule.

It's National Coffee Day! And please note that you can celebrate International Coffee Day on 1 October. As I have reported many times, I don't drink the stuff myself but I do provide daily or more frequent support for Beth's habit/obsession/indulgence.

Today marks the birthday of Friedlieb Ferdinand Runge (1794-1867), a German analytical chemist. Runge identified the mydriatic (pupil-dilating) effects of belladonna extract, identified caffeine, and discovered the first coal tar dye. See this Google Doodle from 2019 for more facts about Runge. Caffeine is "the world's most widely consumed psychoactive drug. Unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world." (Wikipedia) My own favorite caffeine-bearing drink is hot chocolate, which has about 10% of the caffeine concentration in coffee. Our mug helps us remember the chemical structure of caffeine!
