1625: Astronomer Simon Marius dies. He discovered the four largest moons of Jupiter, independently of Galileo Galilei.
1723: Astronomer and mathematician Nicole-Reine Lepaute born. She will predict the return of Halley's Comet, calculate the timing of a solar eclipse, and construct a group of catalogs for the stars.
1812: Joseph Marie Jacquard has dream which inspires him to build a new type of scrying engine.
1895: French army officer Alfred Dreyfus is stripped of his rank and sentenced to life imprisonment on Devil's Island.
1932: Novelist, literary critic, and philosopher Umberto Eco born. He will cite James Joyce and Jorge Luis Borges as the two modern authors who will have influenced his work the most.
1945: Mathematician Dmitry Mirimanoff dies. In 1917, he introduced (though not as explicitly as John von Neumann later) the cumulative hierarchy of sets and the notion of von Neumann ordinals; although he introduced a notion of regular (and well-founded set) he did not consider regularity as an axiom, but also explored what is now called non-well-founded set theory, and had an emergent idea of what is now called bisimulation.
2017: Signed first edition of Two Bugs Fighting sells for an undisclosed amount to "a prominent Gnomon algorithm theorist living in New Minneapolis, Canada.
