==Early life and education==
Witold Hurewicz was born in [[Łódź]], at the time one of the main Polish industrial
Hurewicz attended school in a German-controlled Poland but with [[World War I]] beginning before he had begun [[secondary school]], major changes occurred in Poland. In August 1915 the Russian forces
He studied under [[Hans Hahn (mathematician)|Hans Hahn]] and [[Karl Menger]] in [[Vienna]], receiving a [[
==Career==
Line 14 ⟶ 31:
Hurewicz worked first at the [[University of North Carolina at Chapel Hill]] but during [[World War II]] he contributed to the war effort with research on [[applied mathematics]]. In particular, the work he did on [[servomechanisms]] at that time was classified because of its military importance. From 1945 until his death he worked at the [[Massachusetts Institute of Technology]].
Hurewicz's early work was on [[set theory]] and [[topology]]. The ''[[Dictionary of Scientific Biography]]''
"...a remarkable result of this first period [1930] is his [[topological embedding]] of [[separable space|separable]] [[metric spaces]] into [[compact spaces]] of the same ([[finite set|finite]]) [[dimension]].*"
In the field of [[general topology]] his contributions are centred on [[dimension theory]]. He wrote an important text with [[Henry Wallman]], ''
Hurewicz is best remembered for three remarkable contributions to mathematics: his discovery of the [[higher homotopy groups]] in
In the late 1940s, he was the doctoral advisor of [[Yael Dowker]].
Hurewicz had a second textbook published, but this was not until 1958 after his death.
