A great man in the league of Charles Darwin. A good read!
>>A Prussian-born geographer, naturalist, explorer, and illustrator, Alexander von Humboldt was a prolific writer whose books graced the shelves of American artists, scientists, philosophers, and politicians. Humboldt visited the United States for six weeks in 1804, engaging in a lively exchange of ideas with such figures as Thomas Jefferson and the painter Charles Willson Peale.
Almost 300 plants and 100 animals are named after the Prussian-born naturalist. Have you heard of the Humboldt penguin? The Humboldt Squid, which swims in the Humboldt Current? How about the Humboldt lily, found in California, which also has a Humboldt County? Forests, rivers, peaks, mountain ranges and even a patch of plains on the moon have been named for him. Humboldt, who published 36 books, including his five-volume masterpiece, Cosmos, was a man of many interests—so many that it’s hard to catalog them all.<<
