Boris Semyonovich Tsirelson (May 4, 1950 – January 21, 2020)[2] (Hebrew: בוריס סמיונוביץ' צירלסון, Russian: Борис Семёнович Цирельсон) was a RussianIsraeli mathematician and Professor of Mathematics at Tel Aviv University in Israel, as well as a Wikipedia editor.


Tsirelson was born in Leningrad to a Russian Jewish family. From his father Simeon's side, he was the great-nephew of rabbi Yehuda Leib Tsirelson, chief rabbi of Bessarabia from 1918 to 1941, and a prominent posek and Jewish leader. He obtained his Master of Science from the University of Leningrad and remained there to pursue graduate studies. He obtained his Ph.D. in 1975, with thesis "General properties of bounded Gaussian processes and related questions" written under the direction of Ildar Abdulovich Ibragimov.[1]

Later, he participated in the refusenik movement, but only received permission to emigrate to Israel in 1991. From then until 2017, he was a professor at Tel-Aviv University.

In 1998 he was an Invited Speaker at the International Congress of Mathematicians in Berlin.[3]
