Ernst Friedrich Glocker

Ernst Friedrich Glocker (1 May 1793 – 18 July 1858) was a German mineralogist, geologist, and paleontologist.

Biography
From 1810, he studied theology, philosophy, and sciences at the University of Tübingen, and afterwards, continued his education at Halle. In 1823, he obtained his habilitation with the dissertation thesis, "De Gemmis Plinii inprimis de Topazio", and he later served as a professor at the Magdalene gymnasium in Breslau. In 1834, he became a full professor at the University of Breslau, where he was also director of the mineral cabinet.

During his scientific excursions, he collected minerals and fossils in Silesia, Lusatia, Moravia, and the Sudetenland. He is credited with coining the mineral terms: pyrargyrite (1831), ozokerite (1833), sepiolite (1847), halite (1847), sphalerite (1847), arsenopyrite (1847), and liparite (1847). He also conducted research in the field of botany &mdash; in 1836, paleobotanist Heinrich Göppert named the plant genus Glockeria in his honor.
