Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 1769 – 6 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835).

Humboldt was the son of an officer in the army of Frederick the Great. His mother belonged to a family of Huguenots (French Protestants) who had left France after Louis XIV’s revocation, in 1685, of religious liberty for Protestants. After his father’s death in 1779, he and his brother Wilhelm were raised by their mother, an unemotional woman of strict Calvinist beliefs. They were privately educated; instruction in political history and economics was added to the usual courses in classics, languages, and mathematics, as their mother intended them to be qualified for high public positions. Alexander, a sickly child, at first was a poor student. He was restless, thought of joining the army, and followed his courses only under parental pressure. After futile studies in economics at the University of Frankfurt an der Oder he spent a year in Berlin, where he obtained some training in engineering and suddenly became passionately interested in botany. He began to collect plant specimens in the surroundings of Berlin and learned to classify them. But the poor flora of the province of Brandenburg did not provide much stimulus for an ardent botanist, and Humboldt soon dreamed of journeys to more exotic lands.
A year spent at the University of Göttingen, from 1789 to 1790, finally opened the world of science to him; he became particularly interested in mineralogy and geology and decided to obtain a thorough training in these subjects by joining the School of Mines in Freiberg, Saxony, the first such establishment. Although founded only in 1766, the school had already acquired an international reputation. There, buttressed by a prodigious memory and driven by an unending thirst for knowledge, he began to develop his enormous capacity for work. After a morning spent underground in the mines, he attended classes for five or six hours in the afternoon and in the evening scoured the country for plants.
He left Freiberg in 1792 after two years of intensive study but without taking a degree. A month later he obtained an appointment in the Mining Department of the Prussian government and departed for the remote Fichtel Mountains in the Margraviate of Ansbach-Bayreuth, which had only recently come into the possession of the Prussian kings. Here Humboldt came into his own; he traveled untiringly from one mine to the next, reorganizing the partly deserted and totally neglected pits, which produced mainly gold and copper. He supervised all mining activities, invented a safety lamp, and established, with his own funds, a technical school for young miners. Yet he did not intend to make mining his career.
The conviction had grown in Humboldt that his real aim in life was scientific exploration, and in 1797 he resigned from his post to acquire with great single-mindedness a thorough knowledge of the systems of geodetic, meteorological, and geomagnetic measurements. The political upheavals caused by the Napoleonic Wars prevented the realization of several scientific expeditions in which Humboldt had been given an opportunity to participate. At last, dispirited by his disappointments but refusing to be deterred from his purpose, he obtained permission from the Spanish government to visit the Spanish colonies in Central and South America. These colonies were then accessible only to Spanish officials and the Roman Catholic mission. Completely shut off from the outside world, they offered enormous possibilities to a scientific explorer. Humboldt’s social standing assured him of access to official circles, and in the Spanish prime minister Mariano de Urquijo he found an enlightened man who supported his application to the king for a royal permit. In the summer of 1799 he set sail from Marseille accompanied by the French botanist Aimé Bonpland, whom he had met in Paris, then the liveliest scientific centre in Europe. The estate he had inherited at the death of his mother enabled Humboldt to finance the expedition entirely out of his own pocket. Humboldt and Bonpland spent five years, from 1799 to 1804, in Central and South America, covering more than 6,000 miles (9,650 km) on foot, on horseback, and in canoes. It was a life of great physical exertion and serious deprivation.
Starting from Caracas, they traveled south through grasslands and scrublands until they reached the banks of the Apure, a tributary of the Orinoco River. They continued their journey on the river by canoe as far as the Orinoco. Following its course and that of the Casiquiare, they proved that the Casiquiare River formed a connection between the vast river systems of the Amazon and the Orinoco. For three months Humboldt and Bonpland moved through dense tropical forests, tormented by clouds of mosquitoes and stifled by the humid heat. Their provisions were soon destroyed by insects and rain; the lack of food finally drove them to subsist on ground-up wild cacao beans and river water. Yet both travelers, buoyed up by the excitement provided by the new and overwhelming impressions, remained healthy and in the best of spirits until their return to civilization, when they succumbed to a severe bout of fever.

After a short stay in Cuba, Humboldt and Bonpland returned to South America for an extensive exploration of the Andes. From Bogotá to Trujillo, Peru, they wandered over the Andean Highlands—following a route now traversed by the Pan-American Highway, in their time a series of steep, rocky, and often very narrow paths. They climbed a number of peaks, including all the volcanoes in the surroundings of Quito, Ecuador; Humboldt’s ascent of Chimborazo (20,702 feet [6,310 metres]) to a height of 19,286 feet (5,878 metres), but short of the summit, remained a world mountain-climbing record for nearly 30 years. All these achievements were carried out without the help of modern mountaineering equipment, without ropes, crampons, or oxygen supplies; hence, Humboldt and Bonpland suffered badly from mountain sickness. But Humboldt turned his discomfort to advantage: he became the first person to ascribe mountain sickness to lack of oxygen in the rarefied air of great heights. He also studied the oceanic current off the west coast of South America that was originally named after him but is now known as the Peru Current. When the pair arrived, worn and footsore, in Quito, Humboldt, the experienced mountaineer and indefatigable collector of scientific data, had no difficulty in assuming the role of courtier and man of the world when he was received by the viceroy and the leaders of Spanish society.
In the spring of 1803, the two travelers sailed from Guayaquil to Acapulco, Mexico, where they spent the last year of their expedition in a close study of this most developed and highly civilized part of the Spanish colonies. After a short stay in the United States, where Humboldt was received by U.S. Pres. Thomas Jefferson, they sailed for France.
