Eugen Baumann, German Chemist
Eugen Baumann (1846-1896) was a German chemist. He was one of the first people to create polyvinyl chloride (PVC), and, together with Carl Schotten, he discovered the Schotten-Baumann reaction. The Schotten-Baumann reaction is a method to synthesize amides from amines and acid chlorides. The organosulfur compounds of the urine were his starting point into the physiological chemistry. He identified the source for aromatic compounds in urine being the aromatic amino acids, such as tyrosine. He influenced the organosulfur chemistry by the synthesis of thioacetals and thioketals. These substances were subsequently used by other scientists, for example for anesthesia. Together with his coworkers, he was able to prove that thyroxine was the active ingredient in the thyroid gland. Baumann died at the age of 49 due to a heart problem
