Adolf Ferdinand Weinhold

Adolf Ferdinand Weinhold (1841 to 1917) was a German chemist, physician and inventor. From 1857 to 1861 he studied chemistry and physics at universities in Göttingen and Leipzig, where his mentors were Otto Linné Erdmann and Friedrich Wöhler, and he later worked as a chemist and physician. He was appointed professor at Chemnitz University of Technology in 1870 and was granted a doctorate by the University of Leipzig in 1873. In 1881 he applied the vacuum flask of James Dewar to chemistry, using it as a cold trap; the flask itself was patented in 1903 by the glassblower Reinhold Burger, who founded Thermos GmbH on its basis. His textbooks included the Leitfaden für den physikalischen Unterricht, which ran to 24 editions.
