Responsum Letter by Rebbe Ben Zion [of Bobov] - Ca. Early 20th Century
Responsum letter of Torah thoughts on the laws of shelichut, sent to R. Yitzchak Teitelbaum dayan and posek in Bardiov (Bardejov), signed "Ben Z[ion]". [Bobov?, before 1905?].
The handwriting is similar to that of known letters from the court of Rebbe Ben Zion Halberstam of Bobov. The signature is torn and damaged, making it difficult to compare to other signatures, however, it seems to be the signature of Rebbe Ben Zion Halberstam of Bobov. At the foot of the letter, he writes "Regards from my father"; this indicates that the letter was written before 1905, the year his father, Rebbe Shlomo of Bobov, passed away.
The recipient: R. Yitzchak Teitelbaum (1858-1942, perished in the Holocaust) served as dayan and posek in Bardiov (Bardejov, in German: Bartfeld). He was the disciple of Maharam Schick, and was beloved by the Yitav Lev of Sighet. Likewise, he was revered and cherished by the rebbes of Bobov, R. Shlomo Halberstam and his son R. Ben Zion - author of Kedushat Tzion. Reputedly, when the Kedushat Tzion of Bobov visited Bardiov, of all the prominent rabbis and community notables who came to greet him, he chose R. Yitzchak to sit beside him in the carriage on his way from the train station to his lodgings. He explained his choice by saying: "Do not be surprised that I chose him and none other from among the elder rabbis. This is because my father [Rebbe Shlomo] attested that he learns Torah for the sake of Heaven". R. Yitzchak perished in Auschwitz on 9th Av 1942. Some of his writings were published in the book Divrei Yitzchak.
Rebbe Ben Zion Halberstam, author of Kedushat Tzion (1874-1941, perished in the Holocaust), was the second rebbe of the Bobov dynasty, one of the leading rebbes of his generation and leader of West Galician Jewry. Prominent Torah scholar, clever and sharp, he had an aristocratic demeanour (Encyclopedia L’Chassidut, I, p. 360). He was the son and successor of Rebbe Shlomo (the first) of Bobov, and son-in-law of his great-uncle Rebbe Shalom Eliezer Halberstam of Ratzfert. In 1892, he was appointed Junior Rabbi of Bobov, and already in his father’s lifetime he led the city’s rabbinate and the "holy court". For over 35 years, he served as rabbi and rebbe of thousands of Chassidic families. Many disciples flocked to his yeshiva in Bobov, and under his guidance the studies in the yeshiva reached a very high level. After WWI, he rebuilt the Galician Torah world, establishing the large network of Etz Chaim yeshivot. In the aftermath of WWI and the severe crisis of Galician Chassidism, these yeshivot gave rise to a new generation of Chassidim. He was very active in rabbinical and communal matters, and in 1928, founded the Western-Galicia rabbinic organization. During the Holocaust, he escaped to Lviv, where he was murdered by the Nazis. His son, Rebbe Shlomo (the second) of Bobov, arrived in the United States after the Holocaust and re-established the Bobov Chassidism, which today is one of the largest Chassidic communities in the world.
