The Alsatian Johann Michael Ortlieb (1730-1807) was an industrialist, farmer, winegrower and innkeeper. In 1789, he published a book in which he propagated the improvement of viticulture and the cultivation of the white grape variety Knipperlé (Little Räuschling), which later became known as Ortlieber after him. King Frederick II the Great (1712-1786) had the variety planted experimentally on the "Royal Vineyard" in the Mark Brandenburg. In his work, Ortlieb recommends, among other things, that vines should not be planted on the plains and that the vines should be de-leaved 14 days after blossoming to expose them to the sun. For not altruistic reasons he dedicated the book to King Louis XVI (1754-1793).
