Editing Boruch Ber Leibowitz (section)

== Connection to Chabad ==
Rabbi Leibowitz participated in one of the 12th of Tammuz celebrations with the presence of the baal hageulah, the Frierdiker Rebbe, in the resort town of Drusenick. Rabbi Baruch Ber came especially to visit the Frierdiker Rebbe, and when he arrived, the Frierdiker Rebbe was lying down to rest, so he instructed his son-in-law the Rebbe to receive Rabbi Baruch Ber and converse with him until he would rise. Those present remarked that masechtos of Bavli and Yerushalmi literally 'flew' from their mouths with amazing genius.

During World War I, Reb Baruch Ber stayed in the city of Nevel, and davened for a period in the Chabad shul in the city. Because of this, he even began to wear a gartel during davening, as is the custom of Chassidim.

It is related that on 10th Sivan 5692, during the wedding of Rabbi Menachem Mendel Hornstein (the Frierdiker Rebbe's son-in-law) to Rebbetzin Shaina (the Frierdiker Rebbe's daughter) in Landvarov, Poland, Reb Baruch Ber and Reb Chaim Ozer Grodzinski spoke with appreciation and amazement about the Frierdiker Rebbe's greatness and mesiras nefesh.

In 5692, the Rebbe met with him on a shlichus from the Frierdiker Rebbe. About this meeting it is told: When the Rebbe came to Reb Baruch Ber, the talmidim of Kamenitz Yeshiva surrounded him and 'attacked' him with many questions on sugyos in Shas, but he did not answer. Later, the Rebbe entered Reb Baruch Ber's room, delivered the shlichus message he was sent with from the Frierdiker Rebbe, and went out. After leaving the room, the Rebbe called the talmidim and answered them one by one in a brilliant way on all their questions. Reb Baruch Ber, who stood watching from the side, asked "Initially what was his reasoning and ultimately what was his reasoning?" The Rebbe answered him: "When I was on shlichus, I didn't want to divert my attention to anything else."

On that same occasion, when the Rebbe spoke with Rabbi Baruch Ber's talmidim, during the conversation when Rabbi Baruch Ber heard the greatness of the Rebbe's genius and deep understanding in all parts of Torah, Rabbi Baruch Ber raised his hands upward and said to the Rebbe with enthusiasm: "Come to my yeshiva, and I will make you the gadol hador!" The Rebbe answered him: "But I am a chossid of the Rebbe my father-in-law."

According to another version, this occurred when Rabbi Baruch Ber traveled to his friend Rabbi Chaim Ozer Grodzinski. At that time, the Rebbe came on shlichus from his father-in-law the Frierdiker Rebbe, to get Rabbi Chaim Ozer's signature on a certain proclamation that was issued at that time. The Rebbe waited outside, and during that time Rabbi Baruch Ber's talmidim were pilpuling outside, but the Rebbe did not intervene. Finally, when the Rebbe entered the room where Rabbi Chaim Ozer and Rabbi Baruch Ber were, they asked the Rebbe the reason for his coming, and also asked him about the content of the conversation outside. The Rebbe explained the reason for his coming, and repeated all the Talmudic discussion that was said outside and the many questions, and answered them one by one with amazing genius. Rabbi Baruch Ber was very impressed by the Rebbe's divrei Torah and especially by the depth ("tifkeit") of the answers, and asked the Rebbe to travel with him to learn in his yeshiva where he promised to make him a "godol b'Yisroel," and when he realized this was impossible, he burst into bitter tears.

Rabbi Leibowitz's great-grandson is a Chabad chossid - Rabbi Eliezer Lichtenstein from Yerushalayim.
