RATH, GERHARD VOM (1830-1888), German mineralogist, was born at Dinsburg in Prussia, on the 20th of August 1830. He was educated at Cologne, at Bonn University, and finally at Berlin, where he graduated Ph.D. in 1853. In 1856 he became assistant to Nöggerath in the mineralogical museum at Bonn, and succeeded to the directorship in 1872. Meanwhile in 1863 he was appointed extraordinary professor of geology, and in 1872 he became professor of geology and mineralogy in the university at Bonn. He was distinguished for his accurate researches on mineralogy and crystallography; he described a great many new minerals, some of which were discovered by him, and he contributed largely to our knowledge of other minerals, notably in an essay on tridymite. He travelled much in southern Europe, Palestine and the United States, and wrote several essays on petrology, geology and physical geography, on earthquakes and on meteorites. He died at Coblenz on the 23rd of April 1888.

His separate publications included Ein Ausflug nach Kalabrien (1871); Der Monzoni im südöstlichen Tirol (1875); and Durch Italien und Griechenland nach dem Heiligen Land (2 vols., 1882).
