Dear Rabbi Schachter, Sh'lita Thank you for your presentation on the Eruv last week re: Eruv at the YU museum. If i understood you correctly you mentioned that Rabbi Munk, ZT"L wrote a letter to Chayim Ozer who in turn asked the Chazon Ish re: Eruv in Paris and, he received a Heter. As my wife works together with Rabbi Munk's daughter-Francois Bernhack (Lord Jacobovitz was married to another daughter as well as Rabbi Bronspiegel) I asked her to find out if they used the Paris Eruv. Francois informed my wife that they did *not* use the Paris eruv. Again, if I understood your speech correctly, you indicated that Rabbi Feinstein's ZT"L shita was a 'daas yochid' in his opinion on asering the Eruv. In my neighborhood of Kensington, Brooklyn - all the local rabbis including Chasidish, Misnagdim, Minhag Ahkenaz etc. signed letters against the eiruv. I am sure that you are aware that Rabbi Schwab ZT"L was against Eiruv. I once asked my Rebbi, Rabbi Alpert ZT"L if I could wear a glove on Shabbos. He asked me if I lived in Manhattan. At that time I lived in Queens. He told me to get myself "warm pockets!" My interpretation of his answer was that he would have acceded to wearing gloves in Manhattan; nothing else! On another occasion I asked him if I should be Machmir like Rabbi Feinstein on another matter re: Nidoh. He told me that in *that* inyon Rabbi Feinstein was a daas yochid and I do not need to follow him. So, even though he was a talmid he did not necessarily pasken like his rebbi in everything. If Rabbi Munk did not accept the Paris heter for whatever reason - how could others? There is a story floating around about Rabbi Pam, ZT"L that a baal tshuvah asked him about carrying a handkerchief and he gave him a heter bc of the Eruv. On another occasion a boy asked if he could carry a Sefer from the Torah V'Daas dormitory across the street to the Yeshiva on E9th street, Brooklyn which is not Mefulash. He was told *no*! When asked about the Eruv, he answered, "What Eruv???!" We see that answers to questions vary by circumstances and the level of a person. Giving general answers based on shailos does not always work. In honor of Rav Pam - the people who published the map of the Brooklyn Eruv left out Kensington. The Shita that questions the permissibility of an Eiruv in Manhattan and Brooklyn does not seem like a "daas yochid". So, I do not think that you should have given that impression to your audience. With all due respects, Aurel Littmann
