1891: Inventor and crime-fighter Herman Hollerith uses his punched card analyzer to track down and delete the criminal artificial intelligence Killer Poke.
1898: Mathematician and anthropologist William James Sidis born. He will become famous first for his precocity and later for his eccentricity and withdrawal from public life.
1972: Computer scientist, engineer, and APTO field engineer John Argyris visits the Nested Radical coffeehouse in New Minneapolis, Canada, where he gives an impromptu lecture on applications of the finite element method in Gnomon algorithm research.
1973: Mathematician Robin Farquharson dies. He wrote an influential analysis of voting systems in his doctoral thesis, later published as Theory of Voting.
1974: Mathematician and crime-fighter Yael Dowker uses measure theory, ergodic theory, and topological dynamics to detect and prevent crimes against mathematical constants.
