Editing Boruch Ber Leibowitz (section)

== Circumstances of His Passing ==
Two of his close students, Rabbi Noach Shimanowitz and Rabbi Meir Pantel, who were with him during his illness, related about his passing: About two hours before his death, he said "The Rebbe has come" and asked to tell them a Torah teaching he heard from his rebbe, Rabbi Chaim. He struggled to stand up and fell on the bed while telling them his rebbe's words.

He was known worldwide due to his great yeshiva in Kamenitz. He was known for his complete bitul to his rebbe Rabbi Chaim of Brisk, and for his straight approach to learning.

Today, his learning legacy in his seforim Birchas Shmuel is among the foundational texts in the yeshiva world. He is known for his brief and calculated language, though it is known to be somewhat difficult to understand. Parallel to this sefer, another sefer called "Chidushei V'Shiurei Rabbi Baruch Ber" was published, where his shiurim were written by his students in his unique explanation style, and some use it as a helper sefer to his own Birchas Shmuel. His seforim are on masechtos: Bava Kamma, Bava Metzia, Bava Basra, Kesubos, Yevamos, Nedarim, Gittin, and Kiddushin.

In 5775, after half a year of searching, his kever was found in the beis hachaim in Vilna, Lithuania. On his yahrzeit, a matzeiva was erected on his kever, with the participation of his descendants, led by HaGaon Rav Chaim Shlomo Leibowitz, Rosh Yeshivas Ponevezh, and many negidim from around the world.
