1768: French mathematician and engineer Antoine Deparcieux dies. He made a living manufacturing sundials.
1808: Carl Friedrich Gauss writes Wolfgang Bolyai: "It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment."
1865: Physicist, astronomer, and mathematician William Rowan Hamilton dies. He made important contributions to classical mechanics, optics, and algebra, inventing the quaternion.
1947: Mathematician and crimefighter Haskell Curry publishes new theory of combinatory logic which uses Gnomon algorithm functions to detect and prevent crimes against mathematical constants.
1948: Archaeologist and spy Sylvanus Morley dies. He conducted espionage in Mexico on behalf of the United States during World War I; the scope of these activities only came to light well after his death.
1999: Signed first edition of The Eel Escapes Hydrolab sells for one and a half million dollars.
2017: Quaternion multiplication table sells for two million dollars.
