The man's name is heard everywhere: from the Humboldt Current off the coast of Chile and Peru to dozens of monuments, parks and mountain ranges in South America, including the Humboldt Sierra in Mexico and Humboldt Peak in Venezuela. A city in Argentina, a river in Brazil, a geyser in Ecuador, and a bay in Colombia are named in his honor. In Greenland there is a cape and the Humboldt Glacier, we find the Humboldt Mountains on maps of Northern China, South Africa, New Zealand, Antarctica, the Humboldt rivers and waterfalls are in Tasmania and New Zealand, there are parks named after him in Germany, Alexandra von Street runs through Paris Humboldt. In North America alone, four counties, thirteen cities, mountains, bays, lakes and one river, a natural park in California, parks in Chicago and Buffalo are named after Humboldt, and the state of Nevada almost became the Humboldt State in the 1860s. About 300 plants and more than 100 animals bear his name, including the California Humboldt lily, the South American Humboldt penguin and the ferocious predator, the six-foot-long Humboldt squid, found in the waters of the Humboldt Current. It is immortalized in the names of six minerals, from humboldtite to humboldtine, and one area on the Moon is called Mare Humboldtianum. More places are named after Humboldt than anyone else. Recognized by a dazzling constellation of awards and prestigious honors from the most respected Western scientific communities and media, the book chronicles the life and work of this extraordinary figure—German polymath Alexander von Humboldt (1769–1859), naturalist, zoologist and botanist, traveler and geographer, one one of the founders of physical geography as an independent science, as well as landscape science, ecological geography of plants, geomagnetism and climatology. His ideas were of great importance for the development of science, the field of environmental protection, understanding of the connection between man and nature, art and nature, poetry and nature, politics and nature. Based on many documentary sources, diaries, extensive correspondence, reports on the scientist’s trips, as well as the author’s own travels and research, not only the main milestones of his scientific biography are revealed, but also Humboldt’s character, his emotions, aspirations and weaknesses. A fascinating, intelligent biography, the most comprehensive portrait of one of the world's most versatile naturalists.
