At Moscow conference, Evgeny Velikhov recounts his role in helping an Israeli rabbi open the country’s only official Jewish seminary in 1989.

Russian Jews honored a nuclear physicist who during communism helped establish the only official Jewish religious seminary to open in the former Soviet Union.

At last week’s Limmud FSU conference of Jewish learning in Moscow, Evgeny Velikhov for the first time recounted publicly his involvement in the 1989 opening of the Mekor Chaim Yeshiva while serving as deputy chairman of the Soviet Academy of Sciences.

Velikhov, who is not Jewish, met Adin Even-Israel Steinsaltz, an Israeli mathematician born to secular parents, at a conference in 1988. After being ordained as a rabbi, Steinsaltz became one of the world’s most prominent scholars and interpreters of Jewish texts.

Steinsaltz arrived in Moscow in 1988 as the declining Soviet Union was relaxing its decades-long hostile policy toward religion in general and Judaism specifically.

Russian Chief Rabbi Berel Lazar also spoke at the event, which featured an exhibition celebrating the yeshiva’s 30th anniversary and honoring Steinsaltz, who is 81 years old and living in Jerusalem.

Steinsaltz was the first person “to open the door to the world of Jewish learning” in Russia, Lazar said.

The event was Limmud FSU’s 13th conference and “bar mitzvah celebration,” according to the group’s founder, Chaim Chesler. Limmud FSU now holds events regularly in over 10 countries.
