He studied theology and philology at the University of Berlin, where he served as assistant professor from 1832. He was naturalized as a Prussian citizen in 1833 and was employed in the state archive. He was promoted to Hofrat in 1836 and to Geheimer Archivrat in 1842, from which time he was also professor for political science at Berlin University.
