About Stefan Mazurkiewicz

  • Stefan Mazurkiewicz (25 September 1888 – 19 June 1945) was a Polish mathematician who worked in mathematical analysis, topology, and probability.
  • He was a student of Waclaw Sierpinski and a member of the Polish Academy of Learning (PAU).
  • His students included Karol Borsuk, Bronislaw Knaster, Kazimierz Kuratowski, Stanislaw Saks, and Antoni Zygmund.
  • For a time Mazurkiewicz was a professor at the University of Paris; however, he spent most of his career as a professor at the University of Warsaw.
  • The Hahn–Mazurkiewicz theorem, a basic result on curves prompted by the phenomenon of space-filling curves, is named for Mazurkiewicz and Hans Hahn.
  • His 1935 paper Sur l'existence des continus indĂ©composables is generally considered the most elegant piece of work in point-set topology. During the Polish–Soviet War (1919–21), Mazurkiewicz as early as 1919 broke the most common Russian cipher for the Polish General Staff's cryptological agency.
  • Thanks to this, orders issued by Soviet commander Mikhail Tukhachevsky's staff were known to Polish Army leaders.
  • This contributed substantially, perhaps decisively, to Polish victory at the critical Battle of Warsaw and possibly to Poland's survival as an independent country.
