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.
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.
German-Swiss chemist Christian Friedrich Schönbein created the explosive substance nitrocellulose, or "guncotton", in 1846 by treating cotton fibers with a nitric acid and sulfuric acid mixture. However, guncotton proved to be too fast burning for direct use in firearms and artillery ammunition.
A major step forward was the invention of guncotton, a nitrocellulose-based material, by German chemist Christian Friedrich Schönbein in 1846. He promoted its use as a blasting explosive [8]: 28 and sold manufacturing rights to the Austrian Empire. Guncotton was more powerful than gunpowder, but at the same time was once again somewhat more ...
Christian Friedrich Schönbein HFRSE (18 October 1799 – 29 August 1868) was a German-Swiss chemist who is best known for inventing the fuel cell (1838) [1] at the same time as William Robert Grove and his discoveries of guncotton [2] and ozone. [3] [4] He also created the concept of geochemistry in 1838. [5]

Max Fremery (29 March 1859 – 1 March 1932) was a German chemist and industrialist. He was one of the founders of the Vereinigte Glanzstoff-Fabriken (VGF) in 1899. VGF became a major manufacturer of artificial fibers.
Justus Freiherr von Liebig [a] (12 May 1803 – 20 April 1873) [2] was a German scientist who made major contributions to the theory, practice, and pedagogy of chemistry, as well as to agricultural and biological chemistry; he is considered one of the principal founders of organic chemistry. [3]
