Prof Gustavus ("Gustav") Rose FRSFor HFRSE (18 March 1798 – 15 July 1873) was a German mineralogist who was a native of Berlin. He was President of the German Geological Society from 1863 to 1873.
Rose was a graduate of the University of Berlin, where he was a student of mineralogist Christian Samuel Weiss (1780–1856). He also studied under Swedish people physical chemist Jöns Jakob Berzelius (1779–1848) in Stockholm. While studying with Berzelius, Rose met German chemist Eilhard Mitscherlich (1794–1863), with whom he maintained a lifelong friendship. Rose provided assistance to Mitscherlich's development of the law of isomorphism. In 1826 he became an associate professor of mineralogy in Berlin. In 1829, with German natural history Alexander von Humboldt (1769–1859) and Christian Gottfried Ehrenberg (1795–1876), Rose took part in a scientific expedition throughout Imperial Russia. In Russia he performed mineralogical studies in the Altai Mountains and Ural Mountains, as well as in the region of the Caspian Sea. In 1856 he was appointed director of the Royal Mineralogical Museum. From 1863 up until his death he was president of the German Geological Society.
Rose conducted studies of quartz, , , and the mineralogical components of trap rock. He is remembered for research on meteorites and (grains found in some types of meteorites). With Gustav Tschermak von Seysenegg (1836–1927) and Aristides Brezina (1848–1909), the "Rose-Tschermak-Brezina classification" system of meteorites was developed.
He identified many minerals new to science, including perovskite, named in honor of Russian mineralogist Lev Perovski (1792–1856). A rose-colored mineral named roselite is named after Rose, and he is credited with coining the terms howardite and eucrite.
