Menachem Mendel Futerfas

He was a top student of the famed Mashpia, Reb Zalman Moishe HaYitzchaki.

Futerfas operated clandestine Jewish Cheders in the Soviet Union, for which he was incarcerated for 14 years in Siberian gulags.

[3] After leaving Russia, the Lubavitcher Rebbe, Menachem Mendel Schneerson, instructed him to serve as Mashpia in the Yeshiva of Tomchei Temimim in Kfar Chabad, in Israel.

As hard as he would search, the guard could not find the illicit items.
