Wasserman's style of teaching emphasized the simple meaning of the Talmudic texts and students advanced to the point that they were able to study independently.
The yeshiva went into exile and disbanded a second time during World War II, and Wasserman and many of the students were murdered by Lithuanian Nazi sympathizers.
[7] It was under Wasserman's leadership that the yeshiva gained its widespread fame and a large student body, which eventually numbered in the hundreds.
[10] Due to Wasserman's style of teaching, his students became well-known and sought after in the advanced yeshivas of Lithuania and Poland.
[12][13] In addition to delivering shiurim, Wasserman assumed responsibility for the upkeep of the yeshiva, including instructor salaries and food, shelter, and clothing for the student body.
[15] He traveled frequently to Warsaw and Vilna to fundraise among potential donors, but finances were always tight during the interwar years.
[18] In October 1937 he embarked on a 16-month[19] fundraising tour which brought him to several American cities, including New York, Baltimore, Chicago, St. Louis, Boston, Philadelphia, Cincinnati, Detroit, and Denver.
[20] With the political situation in Europe deteriorating and the prospect of war looming, he was encouraged to remain in the United States.
[22] In June 1940, when the Red Army invaded and occupied Lithuania, the rosh yeshivas and students who were taking refuge there realized that they would not be able to continue functioning under the Soviets.
Although the beis medrash closed in 2000 and the kollel in 2014, the yeshiva is still active, publishing sefarim related to Baranovich as well as running Judaica auctions.
[31] Rabbi Mordechai Lasker, a student of Wasserman in Europe, founded a neighborhood in Bnei Brak called Ramat Elchonon, named after his rebbi.
