Bronisław Knaster was a Polish mathematician who was known for his work in point-set topology.

Mathematical Profile (Excerpt):

• School education proved difficult for young Knaster who entered the first class of the Fourth Junior High School in 1902.
• After the closure of this school in May 1908 and the arrest of many of its students, Knaster moved to the Second Boys Junior High School, at which he completed his school education in 1911 with a silver medal.
• Knaster took a job in the Judicial Department of the Commissariat of the Fourth Civil Guard District of the City of Warsaw.
• Knaster enrolled and began studying logic under Jan Lukasiewicz who had been invited to the new University of Warsaw when it reopened.
• The first students to enter into this high powered mathematical environment were Knaster, Kazimierz Kuratowski and Stanisław Saks.
• Knaster's studies were interrupted, however, by the outbreak of the Polish-Soviet war of 1920.

  Bronisław Knaster

  Polish mathematician (1893–1980)

  Bronisław Knaster (22 May 1893 – 3 November 1980) was a Polish mathematician; from 1939 a university professor in Lwów and from 1945 in Wrocław.^[1]

  In 1945, he completed a project in collaboration with Karol Borsuk and Kazimierz Kuratowski concerning the establishment of the Institute of Mathematics of the Polish Academy of Sciences.^[2]

  He is known for his work in point-set topology and in particular for his discoveries in 1922 of the hereditarily indecomposable continuum or pseudo-arc and of the Knaster continuum, or buckethandle continuum.^[3] Together with his teacher Hugo Steinhaus and his colleague Stefan Banach, he also developed the last diminisher procedure for fair cake cutting.^[4]: 2

  Knaster received his Ph.D. degree from University of Warsaw in 1922 under the supervision of Stefan Mazurkiewicz.^[5]
