Yosef Eliyahu Henkin
Rabbi Henkin in 1937.
He was born in 1881 in Klimavichy, Belarus, then in the Russian Empire, and studied at the Slutzker Yeshiva under Rabbi Isser Zalman Meltzer. He received rabbinical ordination (semichah) from Rabbi Meltzer, and he was also ordained by Rabbi Yaakov Dovid Wilovsky (the Ridvaz), Rabbi Boruch Ber Leibowitz and Rabbi Yechiel Michel Epstein, the Aruch HaShulchan. However, according to the recollections of a student (included in the responsa of Rabbi Henkin's grandson), Rabbi Henkin did not remember receiving ordination from Rabbi Epstein, and for his ordination from Rabbi Wilovsky he was not tested by Wilovsky himself, but by Wilovsky's son-in-law. After serving as rabbi in a number of Russian towns, he emigrated to America in 1922. In 1925 he became the director of Ezras Torah, which provided assistance to scholars. He served in that capacity until his death.
Under his guidance, and following his decisions, Ezras Torah published an annual calendar (luach) listing the synagogue and liturgical customs for each day, specifying the specific practice of that day. Most traditional non-chassidic synagogues in North America followed the decisions of Rabbi Henkin as their baseline.
He had two sons: Louis Henkin, legal academician and writer, and Rabbi Hillel Henkin, educator in Connecticut. His grandson was Rabbi Yehuda Herzl Henkin, an Orthodox rabbi in Israel. Many of Rabbi Yosef Eliyahu Henkin's opinions are only known through the responsa of his grandson.
He was opposed to the practice seen in many yeshivas and synagogues of pausing in the middle of the Rosh Hashanah services for kiddush and refreshments before shofar-blowing. (His stance is defended in his grandson's responsa.)
If a Jewish storekeeper completed a form to sell his chametz to a non-Jew before Passover, yet he kept his store open, selling chametz on Passover and keeping the profits for himself, Rabbi Henkin felt that this proved the "Chametz sale" to be a fraud and therefore invalid. (Rabbi Moshe Feinstein, on the other hand, believed the sale to still be valid.)
Rabbi Henkin felt that in a case where tuna are being caught, it is halachically permissible to check only a few of each batch and not each individual fish; Rabbi Feinstein, on the other hand, felt that each fish needed to be checked for kosher markings that it was in fact, a tuna and not some other fish.
In 1936, Rabbi Henkin declared that Rabbi Yehoshua Seigel's 1905 Manhattan eruv could no longer be relied on because he had only acquired permission for ten years. However, Rabbi Henkin's main argument why the eruv could no longer be relied on was because of the construction of bridges that crossed Manhattan's waterfront (Luach HaYovel Shel Ezras Torah, p. 62). This letter was later reprinted in Edus L'Yisroel, 1949 (p. 151).
Rabbi Henkin was involved in all the discussions about the Manhattan eruv, and on March 15, 1960, he signed on a Statement of the Vaad L'Maan Tikkun Eruvin B'Manhattan (Divrei Menachem, O.C. vol. 2 p. 10) that stated the need to investigate how to bring to fruition the plan for a Manhattan eruv.
On July 12, 1961, Rabbi Henkin wrote a letter stating that there was a sound basis to establish an eruv in Manhattan.(ibid., pp. 14-15; Hapardes 36th year, vol. 4, and Kisvei Hagriah Henkin, pp. 32-33). Yet, he wrote that until the eruv would receive the written support of most of the rabbanim of Manhattan, the permission for the eruv would only be for times of great need.
The prevailing view on this matter appears to be that of Rabbi Henkin's, which may be derived from the fact that as of June 2007, the East Side portion of the internal Manhattan Eruv was completed, offering an eruv within Manhattan to Orthodox Jews living on the East, Upper East, and Upper West Sides. Additionally, there are also two other eruvin in Manhattan's Washington Heights, a neighborhood that also once resisted the drive to establish them; one covering the Yeshiva University area and another covering the Fort Washington area.
Henkin vigorously opposed Zionism, but once the State of Israel was established he declared the need to support its continued existence, and denounced those who tried to undermine it. In 1959 he wrote:
