Friedrich_Adolph_Roemer

Friedrich Adolph Roemer (1809-1869), German geologist, was born at Hildesheim, in Prussia, on the 14th of April 1809. His father was a lawyer and councillor of the high court of justice. In 1845 he became professor of mineralogy and geology at Clausthal, and in 1862 director of the School of Mines. He first described the Cretaceous and Jurassic strata of Germany in elaborate works entitled Die Versteinerungen des Norddeutschen Oolithen-gebirges (1836-39), Die Versteinerungen des Norddeutschen Kreidegebirges (1840-1841) and Die Versteinerungen des Harzgebirges (1843). He died at Clausthal on the 25th of November 1869.

His brother, Carl Ferdinand Von Roemer (1818-1891), who had been educated for the legal profession at Göttingen, also became interested in geology, and abandoning law in 1840, studied science at the university of Berlin, where he graduated Ph.D. in 1842. Two years later he published his first work, Das Rheinische Ubergangsgebirge (1844), in which he dealt with the older rocks and fossils. In 1845 he paid a visit to America, and devoted a year and a half to a careful study of the geology of Texas and other Southern states. He published at Bonn in 1849 a general work entitled Texas, while the results of his investigations of the Cretaceous rocks and fossils were published three years later in a treatise, Die Kreidebildungen von Texas and ihre organischen Einschliisse  (1852), which included also a general account of the geology, and gained for him the title "Father of the geology of Texas." Subsequently he published at Breslau Die Silurische Fauna des westlichen Tennessee (1860). During the preparation of these works he was from 1847 to 1855 "privat-docent" at Bonn, and was then appointed professor of geology, palaeontology and mineralogy in the university of Breslau, a post which he held with signal success as a teacher until his death. As a palaeontologist he made important contributions to our knowledge especially of the invertebrata of the Devonian and older rocks. He assisted H. G. Bronn with the third edition of the Lethaea geognostica (1851-56), and subsequently he laboured on an enlarged and revised edition, of which he published one section, Lethaea palaeozoica (1876-1883). In 1862 he was called on to superintend the preparation of a geological map of Upper Silesia, and the results of his researches were embodied in his Geologie von Oberschlesien (3 vols., 1870). As a mineralogist he was likewise well known, more particularly by his practical teachings and by the collection he formed in the Museum at Breslau. He died at Breslau on the 14th of December 1891.
