Eugen Albert Georg Baumann (born December 12, 1846 in Cannstatt , † November 3, 1896 in Freiburg im Breisgau ) was a German pharmacist, chemist and biochemist .


Eugen Baumann attended the Stuttgart Polytechnic (with a focus on chemistry) and after an apprenticeship in his father's pharmacy, he became a pharmaceutical assistant in Lübeck and Gothenburg . He then studied pharmacy in Tübingen, where he passed the pharmacy exam in 1870 and was awarded a Dr. phil. received his doctorate . He followed his teacher and doctoral supervisor Felix Hoppe-Seyler to Strasbourg, where he completed his habilitation in 1876 as a private lecturer.

He investigated biologically interesting sulfur-containing compounds such as cystine and thioketones . He discovered the conjugated sulfuric acids in the urine and found the sleeping pill sulfonal (diethylsulfondimethylmethane). Together with his students Volkov he discovered in the urine of a Alkaptonurikers the homogentisic and brought them to the metabolism of tyrosine in combination.
