Here is a quizz. What german scientist discovered caffeine( not the peoples who first gave us coffee, just it's chemical properties) and what other vital compound found in another famous drink?

Friedrich (or Friedlieb/Friedlob) Ferdinand Runge (born near Hamburg on 8 February 1795, died in Oranienburg on 25 March 1867) was a German analytical chemist.

Runge conducted chemical experiments from a young age, serendipitously identifying the mydriatic effects of belladonna (deadly nightshade) extract.

In 1819, Runge was given a box of Arabian mocha beans by Johann Wolfgang von Goethe. Goethe asked Runge to analyze the beans. It was from this sample that Runge isolated the world's first sample of pure caffeine. A few months later, Runge identified caffeine.

His chemical work included purine chemistry, the discovery of caffeine, the blue dye aniline, coal tar products (and a large number of substances that derive from coal tar), paper chromatography, pyrrole, chinoline, phenol, thymole and atropine.

Phenol has antiseptic properties, and was used by Sir Joseph Lister (1827–1912) in his pioneering technique of antiseptic surgery, though the skin irritation caused by continual exposure to phenol eventually led to the substitution of aseptic (germ-free) techniques in surgery. Lister decided that the wounds themselves had to be thoroughly cleaned. He then covered the wounds with a piece of "rag" or "lint"[8] covered in carbolic acid. It is also the active ingredient in some oral analgesics such as Chloraseptic spray. Phenol was also the main ingredient of the Carbolic Smoke Ball, a device marketed in London in the 19th century as protecting the user against influenza and other ailments.
