Friedrich Wilhelm Heinrich Alexander von Humboldt (1769 –1859) was a Prussian geographer and explorer.
Humboldt travelled extensively in the Americas, exploring and describing it for the first time from a modern scientific point of view. He was the first person to describe the phenomenon and cause of human-induced climate change, in 1800 and again in 1831, based on observations generated during his travels.
