The historian Andrea Wulf (Germany/UK), winner of the 2013 Eccles Centre & Hay Festival Writer's Award, is the author of the acclaimed and bestselling biography of Alexander von Humboldt (1769-1859), The Invention of Nature (2016). The visionary German naturalist and explorer was an audacious adventurer who helped to create the way we understand nature today. He was the most famous scientist of his times and predicted human-caused climate change. In her book, Wulf follows his footsteps up Andean volcanoes and along the River Orinoco. She also traces his ideas, which revolutionised and moulded science, conservation, nature writing, politics, art and the theory of evolution. She will talk to Sergio Dahbar.
