The Invention of Nature by Andrea WulfRead about another entry on the list.
I knew Alexander von Humboldt's name before I opened this book, but not his story. I read with amazement and fascination of his travels to all corners of the world to discover how all of nature is interconnected. It made me feel lazy. His political views make him a modern thinker, and this book especially illuminates how his science forever changed our worldview. This is science writing at its best.
