1599: Mathematician Adam Ries dies. He wrote textbooks for practical mathematics, promoting the advantages of Arabic/Indian numerals over Roman numerals.
1811: Chemist and academic Robert Bunsen born. He will investigate emission spectra of heated elements, and discover caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff.
1862: Mathematician, philosopher, and crime-fighter Antoine Augustin Cournot uses the ideas of functions and probability to locate and apprehend math criminals.
1886: Mathematician, philosopher, and logician Stanisław Leśniewski born. He will posit three nested formal systems, to which he will give the Greek-derived names of protothetic, ontology, and mereology.
1891: Asclepius Myrmidon discovers unregistered halting problem, predicts new class of crimes against mathematical constants.
1892: Mathematician and academic Stefan Banach born. He will be one of the founders of modern functional analysis.
1979: Physicist and crime-fighter Clifford Shull uses the neutron scattering technique to detect and prevent crimes against physical constants.
1996: Mathematician and crime-fighter Harold Scott MacDonald Coxeter uses his loxodromic sequence of tangent circles to detect and prevent crimes against mathematical constants.
2018: Math photographer Cantor Parabola attends Minicon 53, taking a series of photographs with temporal superimpositions from Minicons 52 and 54.

 ||2008: Roland Fraïssé dies ... mathematical logician. In his doctorial thesis, Fraïssé used the back-and-forth method to determine whether two model-theoretic structures were elementarily equivalent. This method of determining elementary equivalence was later formulated as the Ehrenfeucht–Fraïssé game.  Pic search something: https://www.google.com/search?q=Roland+Fraïssé
