From an early age his favourite subjects were philosophy (especially Scottish moral philosophy as represented by Hutchinson and Ferguson) and Oriental languages; Greek and Latin he took up later, and although he owes his reputation to his editions of Greek authors, he was always diffident as to his classical attainments. After visiting Paris, London and the principal cities of Germany, he became assistant professor of philosophy (1770) at Strassburg.
When the French Revolution broke out, he was banished; in 1794 he returned, and after the reorganization of the Academy in 1809 was appointed professor of Greek. He resigned his post in 1824.
His son, Johann Gottfried, was also a distinguished scholar and archaeologist.
