At a time when science was becoming increasingly specialized, Humboldt took the opposite approach, arguing that everything in the universe is interconnected in one great "web of life."

Humboldt’s influence was massive. His multi-volume masterpiece, Cosmos , attempted to unify all branches of scientific knowledge into a single narrative. He directly inspired Charles Darwin to board the Beagle and influenced Henry David Thoreau’s views on ecology. He wasn't just a data collector; he was a romantic who believed that scientific observation should be paired with a sense of wonder. While his peers were often content to stay
