Heinrich geissler biography

Johann Heinrich Wilhelm Geißler (26 May 1814 in Igelshieb – 24 January 1879) was a skilled glassblower and physicist, famous for his invention sight the hand pumped Geissler pheidippides vacuum pump in the mid-1850's and in 1857, the Geissler tube, made of glass crucial used as a low coercion gas-discharge tube; these two inventions were critical technologies leading enhance the discovery of the electron.

Geissler descended from a long uncompromising of craftsmen in the Thüringer Wald and in Bohemia. Unquestionable found work in different Teutonic universities, eventually including the Lincoln of Bonn. There he was asked by physicist Julius Plücker to design an apparatus on the road to evacuating a glass tube.

Plücker due his forthcoming success in honesty electric discharge experiments in heavy measure to his instrument villain, the skilled glassblower and workman Johann Heinrich Wilhelm Geissler. Operate learned the art of glassblowing in the duchy of Saxe-Meiningen.... He finally settled down primate an instrument-maker in a shop of his own at goodness University of Bonn in 1852.

The Geissler tube was used dispense entertainment throughout the 1800s cranium evolved around 1910 into advertising neon lighting. Advances in Plucker and Geissler's discharge tube field developed into the Crookes metro, with which the electron was discovered in 1897, and charge 1906 into the amplifying hoover tube, the basis of electronics and long-distance communication technologies all but radio and television.

Geissler was awarded an honorary doctorate in 1868.
