Rabbi Yaakov Leiner (the Beit Yaakov) (1814-1878): in his series of books, the Beit Yaakov, he expanded and developed his father’s philosophy (the Mei HaShiloach). His manuscripts on the Books of Numbers and Deuteronomy, and large compositions on writings of the Ari, the te’amim of mitzvot, the order of tefillah, and others were lost in the Shoah. | Rabbi Moshe Eliyahu Halprin (1872-1921) was a speaker and activist of the leaders of Orthodox Jewry in Poland, a member of the Council of Torah Sages of Agudath Israel, and a representative of the Polish Sejm. He was born in Lublin to Rabbi David Meir Halperin, a businessman who was one of the followers of the Rebbe Rabbi Yitzchak Yaakov Rabinowitz of Biala, who grew up in the home of his grandfather Rabbi Itche, one of the greatest bankers in Warsaw. As a prodigy, according to the legend, he had already memorized parts of the Bible as a child. At the age of 10, his parents took him out of the cheder because he was ahead of the pace and hired a special teacher. Later on, he began to hear lessons from the rabbi of the city, Rabbi Shneur Zalman Pardkin, author of Torat Chesed, who is also an autodidact who has acquired mastery in five European languages, history and science. He mingled with scholars, one of whome (Professor Ross), wrote to him: “I have your letters and your poems with those I received from the Reich-Chancellor Bismarck."When he was 15, he first met the Admor Rabbi Gershon Chanoch Leiner, who traveled throughout Europe with the aim of encouraging people to renew the techeiles. The Rebbe then lent him his books, and the next day he became a Chassid, and later he was sent to represent his rabbi's opinion and to argue with the Gaon of Kutna about renewing the commandments of Tekhelet. In 1903, when his friend Rabbi Avraham Bornstein of Sochaczew and the leaders of the Kalish community urged him to serve as rabbi of the town, he refused and went out to bring his friend Rabbi Yechezkel Livshitz to the rabbinate, to manage the religious institutions in the city. From then until the end of his life he lived in the city and served as chairman of the Rabbinical Council. During World War I, Rabbi Halperin began a world-wide activist activity to save Jews from field trials. At the same time, he was also a member of the Agudath Israel movement and became one of its prominent spokesmen. He was later elected as a member of the Council of Torah Sages. In 1919, Rabbi Halperin was elected as representative of Agudath Israel in the Polish Sejm. Rabbi Halperin became famous as a special speaker who challenged local antisemitism. | Original binding, generally ok to good condition.
