Emil Cohen

Emil Wilhelm Cohen ( born October 12, 1842 in Åkjær in Horsens, Denmark, † April 13, 1905 in Greifswald ) was a German mineralogist and Petro graph.

Life

Cohen studied since 1863 in Berlin and Heidelberg, chemistry and physics. He traveled in 1873/74, the gold and diamond fields of South Africa and published one of the first modern descriptions of occurrences. In 1878 he became professor of petrography at Strasbourg University and also the director of the geological mapping of Alsace and Lorraine. He wrote here his " collection of photomicrographs illustrating 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. He examined here, the Nordic sediment and their origin. He also devoted himself to the cosmic petrography, especially with the description of the structure of iron meteorites and minerals contained in them. He isolated and analyzed, for example, an iron carbide, which was later named after him cohenite.

Cohen was in 1883 a member of the German Academy of Sciences Leopoldina.
