Friedrich Wilhelm Christian Karl Ferdinand von Humboldt (22 June 1767 – 8 April 1835) was a Prussian philosopher, linguist, government functionary, diplomat, and founder of the Humboldt University of Berlin, which was named after him in 1949 (and also after his younger brother, Alexander von Humboldt, a naturalist).

He is especially remembered as a linguist who made important contributions to the philosophy of language, ethnolinguistics and to the theory and practice of education. He made a major contribution to the development of liberalism by envisioning education as a means of realizing individual possibility rather than a way of drilling traditional ideas into youth to suit them for an already established occupation or social role. In particular, he was the architect of the Humboldtian education ideal, which was used from the beginning in Prussia as a model for its system of public education, as well as in the United States and Japan. He was elected as a member of the American Philosophical Society in 1822.

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.

Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular).

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".
