He concluded his mineralogical studies at the Universities of Heidelberg and Tübingen resulting in his obtaining his PhD.
Upon his return to Vienna, he qualified as a private lecturer for mineralogy and chemistry. In 1862, Tschermak was appointed
second vice curator of the Imperial Mineralogical Cabinet. In 1867, he advanced to first vice curator. In 1868, Tschermak
took over at the helm of the Cabinet after the death of Director Hoernes. Only a short while prior to this, he was made Professor
of Petrography at the University of Vienna. Tschermak was instrumental in undertaking a detailed inventory of the Imperial
Mineralogical Cabinet which was subsequently run in an exemplary fashion by Rudolf Koechlin along a system which is maintained
even today. One of his other major accomplishments on behalf of the Cabinet was the systematic expansion of the meteorite
In 1873, Tschermak was appointed full professor for mineralogy and petrography at the University of Vienna (known today as
the Institute of Petrology). In 1875, he was elected a full member of the Imperial Academy of Sciences in Vienna, of which
he had been a corresponding member since 1866. Due to his numerous activities at the University, Tschermak left the Imperial
Mineralogical Cabinet in 1877.
Tschermak’s wide-ranging scientific achievements comprise mineralogical works, tests on rocks, and a number of works on meteorites.
He was the first President of the Viennese Mineralogical Society, founded in 1901 (now Austrian Mineralogical Society - Österreichische
Mineralogische Gesellschaft). He died on May 24, 1927. The amphibole mineral tschermakite was named in honour of Tschermak.
