Alexander von Humboldt
1769–1859 · German · Enlightenment / Romantic Era
Known for: Most famous scientist of his age who established biogeography and the concept of nature as interconnected
Alexander von Humboldt was the most famous scientist in the world during his lifetime—more famous than Napoleon in some circles. He explored South America for five years, climbing volcanoes, mapping rivers, discovering species, and nearly dying repeatedly. His books inspired Darwin, who called him 'the greatest scientific traveler who ever lived.'
His masterwork Cosmos attempted to describe the entire physical world in a single work. He established the concept that nature is an interconnected web—essentially inventing ecology and biogeography. The Humboldt Current, dozens of species, and a university are named after him.
