Bronisław Knaster

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

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.[2] Together with his teacher Hugo Steinhaus and his colleague Stefan Banach, he also developed the last diminisher procedure for fair cake cutting.[3]

Knaster received his Ph.D. degree from University of Warsaw in 1925, under the supervision of Stefan Mazurkiewicz.[4]
