Friedrich Wilhelm Christian Karl Ferdinand von Humboldt (, also , ; ; 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. Biography Humboldt was born in Potsdam, Margraviate of Brandenburg, and died in Tegel, Province of Brandenburg. Humboldt's father, Alexander Georg von Humboldt, belonged to a prominent Pomeranian family. 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. He first married the daughter of Prussian General Adjutant Schweder. In 1766, Alexander Georg married Maria Elisabeth Colomb, a well-educated woman and widow of Baron Hollwede, with whom she had a son. Alexander Georg and Maria Elisabeth had three children: a daughter, who died young, and then two sons, Wilhelm and Alexander. Her first-born son, Wilhelm and Alexander's half-brother, was something of a ne'er do well, not often mentioned in the family history. In June 1791, Humboldt married Caroline von Dacheröden. They had eight children, of whom five (amongst them Gabriele von Humboldt) survived to adulthood. Philosopher Humboldt was a philosopher; he wrote The Limits of State Action in 1791–1792 (though it was not published until 1850, after Humboldt's death), one of the boldest defences of the liberties of the Enlightenment. It influenced John Stuart Mill's essay On Liberty through which von Humboldt's ideas became known in
