19992 Schönbein           Discovered 1990 Oct. 10 by F. Borngen and L. D. Schmadel at Tautenburg.
German chemist Christian Friedrich Schönbein (1799-1868) was a professor in Basle from 1828. Best known for his discovery of ozone in 1839, he also invented nitrocellulose and collodion wool. He is considered a cofounder of geochemistry.
