1895: Mineralogist, physicist, and mathematician, and crime-fighter Franz Ernst Neumann uses what is now known as Neumann's Law (the molecular heat of a compound is equal to the sum of the atomic heats of its constituents) to detect and prevent crimes against chemistry.
1930: Mathematician, academic, and rabbi Eliezer 'Leon' Ehrenpreis born. He will prove the Malgrange–Ehrenpreis theorem, the fundamental theorem about differential operators with constant coefficients.
