[3] After World War II, much of orthodox Jewry in Europe was wiped out, along with their many yeshivas (Jewish schools of higher learning).

Some of R' Yeruchom's better known disciples include Simcha Zissel Halevi Levovitz, Avrohom Levovitz, Chaim Shmulevitz, Dovid Povarsky, Isser Yehuda Malin, Aryeh Leib Malin, Abba Berman, Zelik Epstein, Shimon Schwab, Shlomo Wolbe, Zeidel Smiatcky, Aryeh Leib Bakst, Chaim Wysoker, Binyomin Zeilberger, Nachum Partzovitz.

His grave site (recently rebuilt by his family) is a common destination for the many Jewish tourists who visit the decimated cities of pre-war eastern Europe.

Most of R' Yeruchom's family escaped the Nazis and made it to America where they were pioneers of the rebuilding of Orthodox Jewry in the United States.

His son, Rav Simcha Zissel Halevi Levovitz, was the founder of a yeshiva in Boro Park, Brooklyn, and was responsible for publishing the writings of his father, as well as publishing the writings of Rav Simcha Zissel Ziv, the Alter of Kelm.
