When his family moved to Braunschweig, in 1799, he came under the influence of his grandfather, the educator and publisher, Joachim Heinrich Campe.
After participating in several campaigns, he was placed on leave with a foot ailment, possibly caused by poor riding habits, and was discharged in 1815.
After that, he visited England and France where, in Paris, he befriended the chemist, and his future business partner, Justus von Liebig.
That same year, he became a partner in his father's publishing house, bringing in the latest presses and equipment, which he had discovered while traveling.
To this end, from 1831, he published a newspaper, the Deutsche Nationalzeitung aus Braunschweig und Hannover, edited by Karl Heinrich Hermes [de].
