Friedrich Karl Johannes Thiele (May 13 1865 – April 17 1918) was a German chemist and a prominent professor at several universities, including those in Munich and Strasbourg. He developed many laboratory techniques related to isolation of organic compounds. In 1917 he described a device for the accurate determination of melting points, since named Thiele tube after him.

Thiele was born in Ratibor, Prussia, now Racibórz, Poland. Thiele studied mathematics at the University of Breslau but later turned to chemistry, receiving his doctorate from Halle in 1890 . He taught at the University of Munich from 1893 to 1902 , when he was appointed professor of chemistry at Strasbourg.
He developed the preparation of glyoxal bis(guanylhydrazone).
After Kekulé's proposal for benzene structure in 1865, he suggested a "Partial Valence Hypothesis", which concerned double and triple carbon-carbon bonds with which he explains their particular reactivity. This led to the prediction of the resonance that...
