Yisrael Mendel Kaplan

Rabbi Israel Mendel Kaplan or Yisrael Mendel Kaplan (April 14, 1913 – April 4, 1985), known as "Reb Mendel" served as a teacher in the Hebrew Theological College in Chicago and in the Philadelphia Yeshiva to many of the men who were to become the leaders of Orthodox American Jewry.

Yisrael Mendel Kaplan was born in 1913 in Baranovich, Poland (now Baranowicze, Belarus) to Avraham and Esther Kaplan. Avraham was a lawyer and Esther was involved in community service: Raising funds for the Yeshiva, feeding the poor and so forth.

After his bar mitzva, he was enrolled in the yeshiva of Rabbi Elchonon Wasserman. He was considered a very promising student and was assigned Wasserman's son, Naftali, as a study partner. He later studied in the Mir yeshiva as well.

While studying in Mir, he married Sarah Baila Gutman (b. Navahrudak, 1910 – d. New York City, March 12, 2008 ), the daughter of Rabbi Tzvi Hirsch Gutman, the administrator of the yeshiva in Baranowicze. When Rabbi Gutman was looking for a match, he asked Rabbi Elchonon Wasserman about a number of prospects. Rabbi Wasserman recommended Kaplan. When Rabbi Gutman pressed him "Isn't your own son, Naftoli, a little better?" Rabbi Wasserman answered "My Naftoli is a good boy, but he doesn't measure up to Mendel." (Greenwald 1995:31)

They had six children:

In late 1939, the German's Invasion of Poland overtook Poland and the Jews of Baranovich fled for their lives. Wasserman advised his yeshiva students to regroup in then-independent Vilna, Lithuania. Kaplan and his family moved there and Kaplan studied there under Rabbi Yitzchak Zev Soloveitchik. In June 1940, when the Soviet Union occupied Vilna, Jewish life became unbearable. Like the members of the Mir yeshiva and other refugees there, Kaplan sought visas to allow him to escape Nazi and Soviet rule. He obtained a de facto destination visa from the Dutch consul but was unable to obtain the necessary transit visa from Japanese Vice-consul, Chiune Sugihara that would allow his family to detour through Japan while awaiting some final, true destination. (Greenwald 1995:38)
