“Humboldt was one of those wonders of the world, like Aristotle, like Julius Caesar, like the Admirable Crichton, who appear from time to time, as if to show us the possibilities of the human mind, the force and the range of the faculties — a universal man, not only possessed of great particular talents, but they were symmetrical, his parts were well put together. As we know, a man’s natural powers are often a sort of committee that slowly, one at a time, give their attention and action; but Humboldt’s were all united, one electric chain, so that a university, a whole French Academy, travelled in his shoes.”

— Ralph Waldo Emerson, remarks at the centennial celebration of the birth of Alexander von Humboldt, September 14, 1869
