He studied history, theology and philology at the University of Jena, where two of his instructors were Heinrich Luden (1778-1847) and Johann Jakob Griesbach (1745–1812). After graduation, he was an instructor in Halle before becoming a professor at the University of Königsberg in 1817. He died in Königsberg. His son Georg Voigt (1827–1891) was a famous historian.
Johannes Voigt is remembered for his large number of writings concerning the history of Prussia. However, his best-known work was a book about Pope Gregory VII titled ''Hildebrand als Papst Gregor VII und sein Zeitalter''. It is considered an important work because it is an impartial writing by a Protestant who depicts Gregory as a reformer. Provided by Wikipedia
