Johann Heinrich Wilhelm Geißler (26 May 1814 in Igelshieb – 24 January 1879) was a skilled glassblower and physicist, famous for his invention of the hand pumped Geissler mercury vacuum pump in the mid-1850's and in 1857, the Geissler tube, made of glass and used as a low pressure gas-discharge tube; these two inventions were critical technologies leading to the discovery of the electron.: 67  Geissler descended from a long line of craftsmen in the Thüringer Wald and in Bohemia. He found work in different German universities, eventually including the University of Bonn. There he was asked by physicist Julius Plücker to design an apparatus for evacuating a glass tube.
