A poor student when young, he developed a sudden interest in botany that was fully realized at the University of Göttingen, which he attended from 1789 to 1790. After studying at the School of Mines in Freiberg, Saxony, Germany, he received an appointment to the Prussian Mining Department and spent several years re-organizing the mines in a remote section of the Fichtel Mountains. He resigned this post in 1797 to devote himself to scientific exploration, which was put on hold during the Napoleonic Wars.
Finally, in 1799, von Humboldt set off on an epic 6,000-mile expedition through Central and South America with French botanist Aimé Bonpland. His adventures included climbing within 1,500 feet of the 20,702-foot summit of Chimborazo in the Andes - which remained a mountain-climbing record for nearly 30 years - as well as proving that the Casiquiare River connected the Amazon and Orinoco river systems and battling mosquitoes, fever and starvation.Von Humboldt spent from 1804 to 1827 publishing his findings. Among his most important discoveries were the relation of a region's geography to the species inhabiting it and how volcanoes related to the metamorphosis of the Earth's crust. This work nearly bankrupted him, but he persevered, and in the last 25 years of his life published the first four volumes of his massive scientific textbook Kosmos. Written in an accessible, if not always logical, style, Kosmos attempted to correlate all of science then known and became a massive bestseller. A number of species and geographical features have been named after him, including the great Humboldt Current off the coast of South America in the Pacific Ocean.
