of several foreign languages and was known for his aphorisms, to the point that a booklet of his most famous ones in Polish, French and Latin has been published posthumously. In 2002, the Polish Academy of Sciences and Wrocław University sponsored "2002, The Year of Hugo Steinhaus", to celebrate his contributions to Polish and world science. Mathematician Mark Kac, Steinhaus's student, wrote: Chief works Czym jest, a czym nie jest matematyka (What Mathematics Is, and What It Is Not, 1923). Sur le principe de la condensation de la singularités (with Banach, 1927) Theorie der Orthogonalreihen (with Stefan Kaczmarz, 1935). Kalejdoskop matematyczny (Mathematical Snapshots, 1939). Taksonomia wrocławska (A Wroclaw Taxonomy; with others, 1951). Sur la liaison et la division des points d'un ensemble fini (On uniting and separating the points of a finite set, with others, 1951). One of multiple rediscoveries of Borůvka's algorithm. Sto zadań (One Hundred Problems In Elementary Mathematics, 1964). Orzeł czy reszka (Heads or Tails, 1961). Słownik racjonalny (A Rational Dictionary, 1980). Family His daughter Lidya Steinhaus was married to Jan Kott. Grave Steinhaus is buried in Cmentarz Świętej Rodziny in Sępolno, Wrocław, Poland. On November 1, 2017, a controversy arose as the University of Wrocław took no action to pay for his grave to keep it until 2022 in face of its expiration because it supposedly "had no money". Mayor Rafał Dutkiewicz was also widely criticized for doing nothing. Random people organized a charity and paid for the grave to remain.
