Rudolf Christian Böttger (28 April 1806 – 29 April 1881) was a German inorganic chemist. He conducted most of his research at the University of Frankfurt am Main.He is credited with discovery of nitrocellulose in 1846, independently to Schönbein, and with the synthesis of the first organocopper compound copper(I) acetylide Cu 2 C 2 in 1859.
Originally called "Poudre V" from the name of the inventor, Paul Vieille, it was arbitrarily renamed "Poudre B" (short for poudre blanche—white powder, as distinguished from black powder) to distract German espionage. [1] "Poudre B" is made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% ...
Nitrocellulose film on a light box, showing deterioration, from Library and Archives Canada collection. In 1855, the first human-made plastic, nitrocellulose (branded Parkesine, patented in 1862), was created by Alexander Parkes from cellulose treated with nitric acid and a solvent.
Christian Hackenberger grew up in Damme.He attended the Gymnasium Damme, where he obtained his Abitur in 1995. After completing his civil service, he studied chemistry at the Alfred-Ludwig-Universität in Freiberg (1996–1998) and the University of Wisconsin-Madison (M.S. with Samuel H. Gellman, 1998–1999), with support from the German Academic Scholarship Foundation. [4]

Karl Ludwig Freiherr von Reichenbach (German pronunciation: [ˈkaʁl ˈluːtvɪç ˈfʁaɪhɛʁ fɔn ˈʁaɪçn̩bax]; February 12, 1788 – January 19, 1869), known as Carl Reichenbach, was a German chemist, geologist, metallurgist, naturalist, industrialist and philosopher, and a member of the Prussian Academy of Sciences.
Gerhard Schrader (25 February 1903 – 10 April 1990) was a German chemist specializing in the discovery of new insecticides, hoping to make progress in the fight against hunger in the world. Schrader is best known for his accidental discovery of nerve agents including sarin and tabun .
Nobel's patent specified that the nitrocellulose should be "of the well-known soluble kind". He offered to sell the rights of the new explosive to the French government, but they declined. Modern research shows that Vieille already discovered it in 1884-1885, about the same time as his Poudre B , and noted its high flame temperatures leading to ...
