As early as 1794, inspired by his mentors Georg Forster (1754-1794) and Carl Ludwig Willdenow (1765-1812), a 24-year-old Alexander von Humboldt sketched out a research agenda for plant geography in a letter to Friedrich Schiller. Humboldt's overarching plan was no less than the unification of natural and human history. The most iconic result of this research is the well-known "Physical Tableau of the Andes" (Naturgemälde, fig. 1), in which Humboldt depicted the natural vegetation and cultivated plants of the American tropics in their respective elevations.
