He studied sciences at the University of Basel, the Academy of Geneva and at the University of Göttingen (1815–17), where he studied geology under Johann Friedrich Ludwig Hausmann. At Göttingen he became good friends with Bernhard Studer. After obtaining his doctorate, he continued his education in Paris up until 1819, and then returned to Basel and proceeded to conduct geological studies of the Swiss Jura.
In 1820 he was named professor of physics and chemistry at Basel, and during the following year, became director of the Natural History Museum. From 1835 to 1861, he was an honorary professor of geology and palaeontology at Basel, where three times he served as university rector. In 1838 and 1856 he was president of the Schweizer Naturforschenden Gesellschaft.
Known for his scientific investigations of Jura Mountains, he also conducted extensive geological research of the Black Forest, and performed comparison studies of the Germanic and Alpine Triassic stages. During his career, he amassed an impressive collection of fossils, and is credited for developing a classification schema for ammonites. In addition, he made contributions in the fields of meteorology and glaciology.
