763 BC: Assyrians record a solar eclipse that is later used to fix the chronology of Mesopotamian history.
1485 Feb. 1: lexicographer, chronicler, cryptographer, and occultist Johannes Trithemius uses Gnomon algorithm techniques to generate improved solar eclipse forecasts. During the Second World War, this data will be used by German cryptographers to defeat enemy traffic analysis.
1906: Mathematician, cryptographer, and author Gordon Welchman born. During the Second World War, he will develop traffic analysis techniques for breaking German codes.
1939: Art critic and alleged supervillain The Eel helps break German military codes using surf-powered gnomon algorithm techniques.
1995: Physicist, inventor, and academic John Vincent Atanasoff dies. He invented the Atanasoff–Berry computer, the first electronic digital computer.
