After dissolution of the High Karlsschule he was in 1794 overseer in the botanical garden of the Duke. He was editor of many illustrated works, whose pictures were mostly drawn and engraved by himself.

From 1803 to 1815 he made a series of 140 plates, all of them at that time in Germany common grape varieties showed. This allowed in recent times the identification of already extinct grape varieties, such as the 2006 rediscovered on the Badischer Bergstraße Blue Scheuchner, He must not talk to the doctor and contemporary Justinus Kerner (1786-1862), after which the new breed Kerner was named.
