• 

  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.

• 

  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.

• 

  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.

•
