Life

Lossen studied natural sciences in Gießen and Göttingen from 1857 and after receiving his doctorate in 1862 became an assistant in Karlsruhe. Just one year later, he moved to the University of Halle . Since he could not be admitted as a lecturer here as a Catholic according to the statutes, he completed his habilitation in 1866 at the University of Heidelberg , where he taught as an associate professor from 1870. In 1877 he was appointed chemistry professor at the Albertus University in Königsberg (Prussia) and taught there until 1904. In 1887 he was elected a member of the Leopoldina .

He discovered the molecular formula of cocaine in 1862 and hydroxylamine in 1875 .

As an avowed Catholic, he also expressed himself on religious and ecclesiastical issues, for example in the controversy surrounding Albert Ladenburg's rejection of a personal God. He was a founding member of the Görres Society , for which he presented the denominational and regional distribution of university teachers and academics in Prussia in a study based on files from the Prussian government .

His brother was the geologist Karl August Lossen , and their niece was the actress Lina Lossen .

Lossen was married to Bernardine Pelzer, daughter of the Aachen mayor Ludwig Pelzer . He was a member of the Catholic student union Borussia-Königsberg in the KV .
