Life

Johann Gottlieb was born on February 15, 1815 in the Moravian city of Brno as the son of a pharmacist . At an advanced age, Gottlieb himself studied pharmacy at the universities of Vienna and Prague . After completing his studies, he appeared as an assistant to Josef Redtenbacher , whose student he was previously, and was then a private lecturer in Prague before he was appointed professor of general and technical chemistry at the Joanneum , later TU Graz, in 1846 . In the last few months before his death he also acted as rector of the Joanneum, after having been the chair for analytical general chemistry for almost 30 years, and from 1867 to 1868 as director of the university , which was then still known as the Styrian landscape technical university was kicked. After the death of Franz Hruschauer in 1858, the philosophical faculty wanted to make Gottlieb Hruschauer's successor as head of the chemistry chair there. Gottlieb, who worked at the Joanneum under significantly more favorable conditions, set such conditions that there was no official appointment.

Gottlieb had made a name for himself, among other things, through the discovery of various acids. So he discovered in 1844 in the reaction of carbohydrates with molten alkali metal hydroxides , the propionic acid and its salts. The term propionic acid was only given around three years later by the French chemist Jean-Baptiste Dumas . At that time, Gottlieb still referred to it as methacetonic acid . Furthermore, Gottlieb discovered mesaconic acid and gave a detailed description of the representation and composition of the oleic acid discovered by Eugène Chevreul , which Gottlieb presented in pure form for the first time. In addition, Gottlieb analyzed numerous mineral springs in Styria and was a member of the Academy of Sciences in Vienna .
