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.
