Emil Tietze

Emil Ernst August Tietze (15 June 1845, Breslau – 4 March 1931, Vienna) was an Austrian geologist.

He received his education at the Universities of Breslau and Tübingen. Afterwards, he joined the Geological Survey of Austria (1870), an agency that Tietze would be associated with until his retirement in 1918. In 1902 he became its director.

Primarily known for his geological surveys of Eastern Europe (the Carpathian Mountains, Galicia, Bosnia-Herzegovina and Montenegro), he also conducted important research involving the stratigraphy and tectonics in the Elburz Mountains of Persia. Tietze was interested in the processes of erosion that were responsible for modern-day land formations, in particular karst topography.

Tietze's wife, Rosa von Hauer, was the daughter of another notable Austrian geologist, Franz Ritter von Hauer. Their son, Heinrich Franz Friedrich Tietze, became a mathematician.
