Christoph Hawich, his drawing teacher at the Bürgerschule (a type of commercial preparatory school) in Trier noted his artistic talent.
As a result, in 1803 he received a recommendation to study with Jean-Henri Gilson (1741-1809), a former Benedictine monk who taught art in Florenville.
He returned to Trier for ten years, creating hundreds of watercolors of the city and the Moselle River, which he began reproducing as lithographs in 1825.
In 1832, he began another ten-year stay in Italy, producing landscapes and folk-scenes as well as copies of Renaissance frescoes and mosaics.
