||1955: Mathematician Irvin Sol Cohen commits suicide. In his thesis he proved the Cohen structure theorem for complete Noetherian local rings. In 1946 he proved the unmixedness theorem for power series rings. As a result, Cohen–Macaulay rings are named after him and F. S. Macaulay. Cohen and Seidenberg published their Cohen–Seidenberg theorems, also known as the going-up and going-down theorems. No birth date. No pic online.

  • 1744: Mathematician John Hadley dies. Hadley laid claim to the invention of the octant, two years after Thomas Godfrey claimed the same. Hadley also developed ways to make precision aspheric and parabolic objective mirrors for reflecting telescopes.
