Humboldt, Alexander von

Alexander von Humboldt, German naturalist and explorer, 1769-1859

Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in Latin America, exploring and describing it for the first time from 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. Humboldt resurrected the use of the word cosmos from the ancient Greek and assigned it to his multi-volume treatise, Kosmos, in which he sought to unify diverse branches of scientific knowledge and culture.
