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.
1933: Ready Kilowatt performs in off-Broadway adaption of Reddy Kilowatt Versus the Travelling Salesman Problem.
