Stein studied at the yeshiva in Breinsk, and later at the Slonim Yeshiva under Rabbi Shabsi Yogel.
In 1936 Stein went to study in the Mir Yeshiva in Poland, where he formed a close relationship with the rosh yeshiva, Rabbi Eliezer Yehuda Finkel. With the start of World World War II, Stein fled with the Mir Yeshiva to Vilna and then to Shanghai, where he spent the remainder of the war. During this time, Stein formed a relationship with the Mashgiach, Rabbi Yechezkel Levenstein.
After the war, he joined the remainder of the Mir yeshiva students in New York, where the yeshiva had re-opened.
Foreign a short period, he joined a group of students who went to Cincinnati, Ohio, where Rabbi Eliezer Silver had founded a yeshiva. In 1948, Stein married the daughter of Rabbi Zalman Bloch, who had been the menahel ruchani of the Telz Yeshiva in Lithuania.
At the time, Rabbi Stein was the only rosh yeshiva not to have studied in Telz and so his methodology and approach to Talmudic analysis were unique to the yeshiva. In 1988, Stein"s oldest son, Rabbi Shmuel Zalman, died at the age of 38.
He was the author of Pri Shmuel, and delivered a shiur at the Heichal HaTorah Yeshiva in Jerusalem.
