Heinrich Geissler

(Johann Heinrich Wilhelm Geissler)


Igelshieb 26.May.1814-Bonn 24.January.1879
1855 Cathode ray tube-production
 Further mercury for pump to the production of blank 
Since 1855, Geissler builds a vacuum pump mercury for the production of empty very driven (1 / 100 millimeters of mercury). In 1858, Plücker appeals to his dexterity for the construction series of rarefied gas pipes, which gave its name 'Geissler tubes'.  Gassiot (friend of Faraday) presents a statement in 1858 that certifies testing with vacuum tubes in the laboratories of the Royal Society.
