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's quantitative work on botanical geography laid the foundation for the field of biogeography, while his advocacy of long-term systematic geophysical measurement pioneered modern geomagnetic and meteorological monitoring. Humboldt and Carl Ritter are both regarded as the founders of modern geography as they established it as an independent scientific discipline.
Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a non-Spanish European scientific point of view. On these travels, along with French explorer Aimé Bonpland, he traversed thousands of miles through some of the most difficult and little-known places on Earth, to include identifying the source of the Orinoco River and in 1802 climbing the highest mountain in Ecuador to a height of 19,286 feet, at the time a world record altitude for a Westerner. His description of the journey was written up and published in several volumes over 21 years.
Humboldt resurrected the use of the word cosmos from the ancient Greek and assigned it to his multivolume treatise, Kosmos, in which he sought to unify diverse branches of scientific knowledge and culture. This important work also motivated a holistic perception of the universe as one interacting entity, which introduced concepts of ecology leading to ideas of environmentalism. In 1800, and again in 1831, he described scientifically, on the basis of observations generated during his travels, local impacts of development causing human-induced climate change.
Humboldt is seen as "the father of ecology" and "the father of environmentalism".
Early life, family and education
Alexander von Humboldt was born in Berlin in Prussia on 14 September 1769. He was baptized as a baby in the Lutheran faith, with the Duke of Brunswick-Wolfenbüttel serving as godfather.
His father, Alexander Georg von Humboldt (1720–1779), belonged to a prominent German noble family from Pomerania. Although not one of the titled gentry, he was a major in the Prussian Army, who had served with the Duke of Brunswick. At age 42, Alexander Georg was rewarded for his services in the Seven Years' War with the post of royal chamberlain. He profited from the contract to lease state lotteries and tobacco sales.
Alexander's grandfather was Johann Paul von Humboldt (1684–1740), who married Sophia Dorothea von Schweder (1688–1749), daughter of Prussian General Adjutant Michael von Schweder (1663–1729). In 1766, his father, Alexander Georg married Maria Elisabeth Colomb, a well-educated woman and widow of Baron Friedrich Ernst von Holwede (1723–1765), with whom she had a son Heinrich Friedrich Ludwig (1762–1817). Alexander Georg and Maria Elisabeth had four children: two daughters, Karoline and Gabriele, who died young, and then two sons, Wilhelm and Alexander. Her first-born son, Wilhelm and Alexander's half-brother, Rittmaster in the Gendarme regiment was something of a ne'er-do-well, not often mentioned in the family history.
Alexander Georg died in 1779, leaving the brothers Humboldt in the care of their emotionally distant mother. She had high ambitions for Alexander and his older brother Wilhelm, hiring excellent tutors, who were Enlightenment thinkers, including Kantian physician Marcus Herz and botanist Carl Ludwig Willdenow, who became one of the most important botanists in Germany. Humboldt's mother expected them to become civil servants of the Prussian state. The money left to Alexander's mother by Baron Holwede became instrumental in funding Alexander's explorations after her death; contributing more than 70% of his private income.
Due to his youthful penchant for collecting and labeling plants, shells, and insects, Alexander received the playful title of "the little apothecary". Marked for a political career, Alexander studied finance for six months in 1787 at the University of Frankfurt (Oder), which his mother might have chosen less for its academic excellence than its closeness to their home in Berlin. On 25 April 1789, he matriculated at the University of Göttingen, then known for the lectures of C. G. Heyne and anatomist J. F. Blumenbach. His brother Wilhelm was already a student at Göttingen, but they did not interact much, since their intellectual interests were quite different. His vast and varied interests were by this time fully developed.
At the University of Göttingen, Humboldt met Steven Jan van Geuns, a Dutch medical student, with whom he travelled to the Rhine in the fall of 1789. In Mainz, they met Georg Forster, a naturalist who had been with Captain James Cook on his second voyage. Humboldt's scientific excursion resulted in his 1790 treatise Mineralogische Beobachtungen über einige Basalte am Rhein (Brunswick, 1790) (Mineralogic Observations on Several Basalts on the River Rhine). The following year, 1790, Humboldt returned to Mainz to embark with Forster on a journey to England, Humboldt's first sea voyage, the Netherlands, and France. In England, he met Sir Joseph Banks, president of the Royal Society, who had travelled with Captain Cook; Banks showed Humboldt his huge herbarium, with specimens of the South Sea tropics. The scientific friendship between Banks and Humboldt lasted until Banks's death in 1820, and the two shared botanical specimens for study. Banks also mobilized his scientific contacts in later years to aid Humboldt's work. In Paris, Humboldt and Forster witnessed the preparations for the Festival of the Federation. Yet, Humboldt's take on the French Revolution remained ambivalent.
Humboldt's passion for travel was of long standing. He devoted to prepare himself as a scientific explorer. With this emphasis, he studied commerce and foreign languages at Hamburg, geology at Freiberg School of Mines in 1791 under A.G. Werner, leader of the Neptunist school of geology; from anatomy at Jena under J.C. Loder; and astronomy and the use of scientific instruments under F.X. von Zach and J.G. Köhler. At Freiberg, he met a number of men who were to prove important to him in his later career, including Spaniard Manuel del Río, who became director of the School of Mines the crown established in Mexico; Christian Leopold von Buch, who became a regional geologist; and, most importantly, Carl Freiesleben, who became Humboldt's tutor and close friend. During this period, his brother Wilhelm married, but Alexander did not attend the nuptials.
Humboldt graduated from the Freiberg School of Mines in 1792 and was appointed to a Prussian government position in the Department of Mines as an inspector in Bayreuth and the Fichtel Mountains. Humboldt was excellent at his job, with production of gold ore in his first year outstripping the previous eight years. During his period as a mine inspector, Humboldt demonstrated his deep concern for the men laboring in the mines. He opened a free school for miners, paid for out of his own pocket, which became an unchartered government training school for labor. He also sought to establish an emergency relief fund for miners, aiding them following accidents.
Humboldt's researches into the vegetation of the mines of Freiberg led to the publication in Latin (1793) of his Florae Fribergensis, accedunt Aphorismi ex Doctrina, Physiologiae Chemicae Plantarum, which was a compendium of his botanical researches. That publication brought him to the attention of Johann Wolfgang von Goethe, who had met Humboldt at the family home when Alexander was a boy, but Goethe was now interested in meeting the young scientist to discuss metamorphism of plants. An introduction was arranged by Humboldt's brother, who lived in the university town of Jena, not far from Goethe. Goethe had developed his own extensive theories on comparative anatomy. Working before Darwin, he believed that animals had an internal force, an urform, that gave them a basic shape and then they were further adapted to their environment by an external force. Humboldt urged him to publish his theories. Together, the two discussed and expanded these ideas. Goethe and Humboldt soon became close friends.
