(born March 22, 1785, Dent, Yorkshire, Eng.—died Jan. 27, 1873, Cambridge, Cambridgeshire) English geologist. A pioneer in the establishment of geology as a university discipline (Trinity College, Oxford), he named the Cambrian Period and (with Roderick Murchison) the Devonian Period. His grandnephew, the zoologist Adam Sedgwick (1854–1913), first established the evolutionary link between the annelids and the arthropods.
