Joachim Heinrich Campe (1746 – 1818) was a German writer, linguist, educator and publisher. Probably his best-known work is his Robinson der Jüngere (1779/80), a free adaptation of Daniel Defoe’s Robinson Crusoe (1719). In 1787 Campe founded his own publishing house, the Braunschweigische Schulbuchhandlung. Intrigued by the political movements in France in 1789, Campe and his former pupil Wilhelm von Humboldt travelled to Paris.
