He was a former student of Wacław Sierpiński, earning his doctorate in 1913 from the University of Lwów; his thesis concerned continuous functions that are not differentiable.[1] He became a professor at the same university (then named Jan Kazimierz University) and rector of the Academy of Foreign Trade in Lwów. During the Second World War, Ruziewicz's home city of Lwów was annexed by the Ukrainian Soviet Socialist Republic, but then taken over by the General Government of German-occupied Poland in July 1941; Ruziewicz was arrested and murdered by the Gestapo on 12 July 1941 in Lviv, during the Massacre of Lviv professors.[2]The Ruziewicz problem, asking whether the Lebesgue measure on the sphere may be characterized by certain of its properties, is named after Ruziewicz.[3] References1. ^{{MathGenealogy |id=123308}} {{Authority control}}{{DEFAULTSORT:Ruziewicz, Stanislaw}}{{Poland-mathematician-stub}}2. ^Wacław Sierpiński, as quoted in {{citation | last = Rotkiewicz | first = A. | doi = 10.1007/BF02844227 | journal = Rendiconti del Circolo Matematico di Palermo | series = Serie II | mr = 0323676 | pages = 5–24 | title = W.
