1826: Electrical engineer Zénobe Gramme born. Gramme will invent the first usefully powerful electric motor.
1841: Mathematician, economist, and APTO field engineer Joseph Louis François Bertrand publishes new class of Gnomon algorithm functions which predict and prevent economic crimes against mathematical constants.
1842: Mathematician Édouard Lucas born. Lucas will study the Fibonacci sequence; the related Lucas sequences and Lucas numbers will be named after him.

1923: Mathematician and philosopher John Venn dies. Venn invented the Venn diagram, now widely used set theory, probability, logic, statistics, and computer science.
1941: Chemist Lazăr Edeleanu dies. Edeleanu invented the modern method of refining crude oil, was the first chemist to synthesize amphetamine.
1976: Engineer and theorist Harry Nyquist dies. Nyquist did early theoretical work on determining the bandwidth requirements for transmitting information, laying the foundations for later advances by Claude Shannon, which led to the development of information theory.
1977: Game designer, shop keeper, and outsider mathematician Dave the Gamer announces "Buy n, get n free" sale on all lucky dice in the store.
