Schonbein subsequently showed the solution possessed reducing properties.
CHRISTIAN FRIEDRICH SCHONBEIN (1799-1868), chemist, was born at Metzingen, Swabia, on the 18th of October 1799, and died at Sauersberg, near Baden Baden, on the 29th of August 1868.
Schonbein of Basel published his discovery of guncotton in 1846 (Phil.
Immediately after the discovery of guncotton SchOnbein proposed its employment as a substitute for gunpowder, and General von Lenk carried out a lengthy and laborious series of experiments intending to adapt it especially for artillery use.
Schonbein (loc. cit.) assumed that the ordinary oxygen molecule is decomposed into two parts which carry electrical charges of opposite kinds, the one with the positive charge being called "antozone" and the other carrying the negative charge being called "ozone," one variety being preferentially used up by the oxidizing compound or element and the other for the secondary reaction.
It is certain that the formation of hydrogen peroxide and ozone accompany the glowing, and in 1848 Schonbein tried to demonstrate that it.
