Frederick the Great Quotes
Euler calculated the force of the wheels necessary to raise the water in a reservoir ... My mill was carried out geometrically and could not raise a drop of water fifty yards from the reservoir. Vanity of vanities! Vanity of geometry!
Frederick II. Letter to Voltaire, 25 January 1778. Oeuvres de Frédéric le Grand, edited by J.D.E. Preuss, vol. 23, Imprimerie Royale, 1853, p. 438.
Frederick II was a Prussian king and military leader who ruled the Kingdom of Prussia from 1740 until 1786, reigning longer than any other Hohenzollern king. His most significant accomplishments during his reign included his reorganization of Prussian armies, his military successes in the Silesian wars and the Partitions of Poland, and his patronage of the arts and the Enlightenment. Frederick was the last Hohenzollern monarch titled King in Prussia and declared himself King of Prussia after annexing strategic parts of the Polish–Lithuanian Commonwealth in 1772. Prussia greatly increased its territories and became a leading military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "The Old Fritz" (German: "Der Alte Fritz") by the Prussian people and eventually the rest of Germany.
