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.
