Google honours German chemist Runge with an animated doodle on his 225th birthday
Internet search engine and technology giant Google honours German chemist Friedlieb Ferdinand Runge on his 225th birthday on February 8, 2019, with an animated doodle.

Runge had identified caffeine for the first time and doodle depicts the chemistry and use of coffee by modifying the logo and showing an animated picture of a person sipping coffee from a cup.

As a curious and exploring child, Runge showed his keen interest in chemistry and began experimenting with the extracts of plants and their composition which became his lifelong passion.

In his early years, Runge had got a drop of belladonna extract in his eye accidently and keenly observed its effect on his pupil of the eye to discover that it dilated the pupil.

As a higher education student he studied under chemist Johann Wolfgang Dobereiner at University of Jena to identify caffeine. Later, he did his doctorate from the University of Berlin and also taught at the University of Breslau.

He invented the first coal tar dye, quinine, paper chromatography and is credited for devising an effective method for getting sugar from beet juice.
