Emil Cohen
Emil Wilhelm Cohen (born October 12, 1842 in Akjär near Horsens , Denmark, † April 13, 1905 in Greifswald ) was a German mineralogist and petrographer .
Life
From 1863 Cohen studied chemistry and physics in Berlin and Heidelberg. In 1873/74 he toured the gold and diamond fields of South Africa and published one of the first modern descriptions of the deposits. In 1878 he became professor of petrography at the University of Strasbourg and at the same time director of the geological survey of Alsace and Lorraine . Here he wrote his “collection of microphotographs to illustrate the microscopic structure of minerals and rocks” and thus became one of the founders of modern petrography.
In 1885 he became professor of mineralogy and geology at the University of Greifswald . Here he examined the Nordic debris and its origin. He also devoted himself to cosmic petrography , especially describing the structure of iron meteorites and the minerals they contain. For example, he isolated and analyzed an iron carbide that was later named cohenite after him .
From 1883 Cohen was a member of the German Academy of Sciences Leopoldina .
