Friedrich Wilhelm Heinrich Alexander Freiherr von Humboldt 1769 – 1859 was a German naturalist and explorer, and the younger brother of the Prussian minister, philosopher, and linguist, Wilhelm von Humboldt. Humboldt’s quantitative work on botanical geography was foundational to the field of biogeography.
Alexander von Humboldt was a profound influence on Charles Darwin, who was given a copy of Alexander von Humboldt’s Personal Narrative of travels to the equinoctial regions as a parting gift when he set off on his travels on the Beagle by his friend John Stevens Henslow. Charles Darwin said of Alexander von Humboldt ‘… like another sun’ Humboldt ‘… illumines everything I behold’.
Alexander von Humboldt was a friend of Jean Louis Rodolphe Agassiz, Constance Marie Theis Princess de Salm Dyck (a close friend of Melanie Hahnemann), Joseph Hyppolyte Pulte (one of the first pioneers of homeopathy in America who remains a widely influential homeopath today),
Between 1799 and 1804, Alexander von Humboldt traveled extensively in Latin America, exploring and describing it for the first time in a manner generally considered to be a modern scientific point of view.
His description of the journey was written up and published in an enormous set of volumes over 21 years.
He was one of the first to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Later, his five volume work, Kosmos (1845), attempted to unify the various branches of scientific knowledge.
Humboldt supported and worked with other scientists, including Joseph Louis Gay Lussac, Justus von Liebig, Jean Louis Rodolphe Agassiz, Matthew Fontaine Maury, and most notably, Aime Bonpland, with whom he conducted much of his scientific exploration.
