Letter from Rabbi Isser Zalman Meltzer, for Strengthening the Education in Charedi Schools
Interesting letter from Rabbi Isser Zalman Meltzer, to strengthen "Mercaz Chinuch HaTorah" in Eretz Israel. [Jerusalem 1937?].
Mercaz Chinuch HaTorah BeEretz Israel was established in 1936, by Rabbi Reuven Katz of Petach Tikva, and disciple of Rabeinu Isser Zalman. The Organization was founded in order to battle against secular education and to preserve the independence of Torah education in Charedi schools.
The letter is written in [autographic?] handwriting and signed by Rabbi Isser Zalman. An important and sharp letter about the importance of Torah education, and against the compromising "Dati" education, which, to his words, was leaning far too close to resembling the irreligious sect.
The wording of Rabbi Isser Zalman's letter, which reveals, if but in a small way, the aims of the Mercaz, is evidence that he was among the leaders and pioneers of this organization. The Chazon Ish also stood behind the scenes of the Mercaz. His brothers-in-law, Rabbi Shmuel Greiniman and Rabbi Nachum Karelitz, were very involved in the Mercaz, which established new schools for boys and girls and did much to strengthen the students of the religious schools. See enclosed material for more about this organization.
