Edward Marczewski (born November 15, 1907 in Warsaw , † October 17, 1976 in Breslau ) was a Polish mathematician . His last name was Szpilrajn until 1940 .

Grave in Wroclaw

He was a member of the Warsaw School of Mathematics . His life and work after World War II were linked to Wroclaw, where he became one of the founders of the Polish Science Center.

Marczewski studied from 1925 at the University of Warsaw , where he was a student of Kazimierz Kuratowski , Waclaw Sierpinski and Stefan Mazurkiewicz . In 1932 he received his doctorate from Sierpinski. When German troops invaded Poland in 1939, he was a visiting scientist in Lemberg, but soon returned to Warsaw. At the end of the war he was in a labor camp in Breslau until liberation by Soviet troops. He stayed in Breslau and rebuilt the Mathematical Institute there as a professor of mathematics with Hugo Steinhaus and others. Lectures began there in November 1945. Marczewski was temporarily rector of the university.

In 1946 he founded the journal Colloquium Mathematicum, of which he was editor for thirty years. He was general secretary of the Polish Mathematical Institute founded in 1948.

Marczewski's fields of interest were measure theory , descriptive set theory , topological geometry , probability theory and algebra . He also published papers on the analysis of real and complex numbers, on applied mathematics and on mathematical logic . The szpilrajn extension theorem and the Separabilitätssatz of Marczewski bears his name.

A conjecture by Marczewski about Banach-Tarski decompositions from 1930 was proven by Matthew Foreman and Randall Dougherty around 1990 .

At first he also published under the names Szpilrajn and Szpilrajn-Marczewski (as a Jew he took a Polish name and had to use his first name as a double name for a while).
