1531: Mathematician, astronomer, astrologer, priest, maker of astronomical instruments, and professor Johannes Stöffler dies.
1698: Mathematician, geophysicist, and astronomer Pierre Bouguer born. He will be known as "the father of naval architecture".
1754: Physician and astrologer Richard Mead dies. His work, A Short Discourse concerning Pestilential Contagion, and the Method to be used to prevent it (1720), was of historic importance in the understanding of transmissible diseases.
1822: Statistician, progressive, polymath, sociologist, psychologist, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, and psychometrician Francis Galton born.
1852: The Orcagna scrying engine discovers "at least two megabytes" of previously unknown Gnomon algorithm functions from the lost work of Abū Sahl al-Qūhī.
1922: Mathematician Hing Tong born. He will provide the original proof of the Katetov–Tong insertion theorem.
1927: Botanist and chemist Friedrich Reinitzer dies. In late 1880s, experimenting with cholesteryl benzoate, Reinitzer discovered the properties of what would later be called liquid crystals; although the discovery attracted attention, interest soon faded as no practical uses were found at the time.
1960: Mathematician and crime-fighter The Eel (left) stops aquatic cryptid and alleged supervillain Neptune Slaughter (right) from infiltrating Operation Sandblast, the U.S. Navy submarine circumnavigation of the globe.
1960: The U.S. Navy submarine USS Triton begins Operation Sandblast, setting sail from New London, Connecticut, to begin the first submerged circumnavigation of the globe.
1979: Mathematician and crime-fighter Nicolaas Govert de Bruijn publishes new class of Gnomon algorithm functions which use combinatorial number logic to detect and prevent crimes against mathematical constants.
1997: Physicist Chien-Shiung Wu dies. She conducted the Wu experiment, which contradicted the law of conservation of parity, proving that parity is not conserved.
