| ||1842: Emil Christian Hansen born ... mycologist who revolutionized beer-making through development of new ways to culture yeast. He financed his education by writing novels. Though he never reached an M.Sc., in 1876, he received a gold medal for an essay on fungi. In 1879, he became superintendent of the Carlsberg breweries. In 1883, he successfully developed a cultivated yeast that revolutionized beer-making around the world, because Hansen by refusing to patent his method made it freely available to other brewers. He also proved there are different species of yeast. Hansen separated two species: Saccaromyces cerevisae, an over-yeast (floating on the surface of the fermenting beer) and S. carlsbergensis*, an under-yeast (laying on the bottom of the liquid). Pic.

| ||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.
