Life
Rajchman was born in Congress Poland , which was then part of the Russian Empire, and studied in Paris , where he obtained his licentiate in 1910. In 1919 he became an assistant at the University of Warsaw . In 1921 he received his doctorate under Hugo Steinhaus at the University of Lwow (Lemberg) .

In 1940 he was arrested as a Jew by the Gestapo and died in the Sachsenhausen concentration camp .
In the 1930s he was also a visiting professor in Jacques Hadamard's seminar at the Collège de France . He dealt in particular with Fourier series . His best-known student was Antoni Zygmund , with whom he published three works and who built an important school of harmonic analysis in Chicago . Zygmund dedicated his monumental work Trigonometric Series to his teacher Rajchman (and his student Józef Marcinkiewicz ) and also wrote an obituary for Rajchman in 1987. The Banach Center hosted a symposium in 2000 in honor of Marcinkiewicz, Rajchman, Zygmund.
Rajchman algebras and Rajchman measures are named after Rajchman .
