K-cup – “where did you hear Rav Hutner and the rebbe were chavrusas?”
My husband was a talmid of Rav Hutner and every so often the Rosh Yeshiva would mention fondly of learning with the Lubavitcher Rebbe (however, that might have been when they were both in Sorbonne days in Paris during WW2).
If you want more on the subject, there is a new book (I did not see it and cannot vouch for it): Rabbi Hutner and Rebbe, (JEP, March 2019), by Rabbi Chaim Dalfin of Boro Park. I hope it is respectful and accurate.
Reviews state that the book is dedicated to the relationship and correspondence between Rabbi Hutner and the Lubavitcher Rebbe, which began in the University of Berlin and carried on until Rabbi Hutner’s passing prior to Pesach in 1980.
Rav Hutner had a talmid by the name of Freifeld. Rav Hutner said to Freifeld on the day he was niftar that he wants to tell him something but he shouldn’t be upset. “There’s one Tzadik in the world and he lives on Eastern Parkway”.
The great ones respected each other greatly.
