Born Mar. 14, 1882, in Warsaw; died there Oct. 21, 1969. Polish mathematician.
Sierpiński graduated from Warsaw University in 1904 and was a professor there from 1918 to 1960. Between 1917 and 1951 he was a member of the Academy of Learning in Kraków. In 1952 he became a member of the Polish Academy of Sciences, which was established in Warsaw to replace the Kraków Academy of Learning and the Warsaw Scientific Society. He was vice-president of the Polish Academy of Sciences from 1952 to 1957.
Sierpinski’s principal works deal with the theory of functions of a real variable, with set theory, and with the applications of set theory to topology. Together with the Polish mathematicians Z. Janiszewski and S. Mazurkiewicz he founded in 1920 the journal Fundamenta mathematicae, which is devoted to set theory and its applications.
