||1905: Karol Borsuk born ... mathematician. His main interest was topology. Borsuk introduced the theory of absolute retracts (ARs) and absolute neighborhood retracts (ANRs), and the cohomotopy groups, later called Borsuk–Spanier cohomotopy groups. He also founded Shape theory. He has constructed various beautiful examples of topological spaces, e.g. an acyclic, 3-dimensional continuum which admits a fixed point free homeomorphism onto itself; also 2-dimensional, contractible polyhedra which have no free edge. His topological and geometric conjectures and themes stimulated research for more than half a century.

||1932: Heinz-Dieter Zeh born ... a professor (later professor emeritus) of the University of Heidelberg and theoretical physicist. He was one of the developers of the many-minds interpretation of quantum mechanics and the discoverer of decoherence, first described in his seminal 1970 paper.
