Distinguished Lubavitch Rav
Rabbi Meir Greenberg and the Large-City Eruv Proclamation of 5739
Rabbi Meir Greenberg's name appears on two public rabbinic notices from 5739. Unlike Rabbi Yaakov Kassin and Rabbi Yosef Harari-Raful, no separate first-person statement by Rabbi Greenberg has been located in these surviving proclamations. What can be attributed to him here is therefore his printed inclusion with the collective text.
The sixteen-name Union of Orthodox Rabbis proclamation
A Kislev 5739 proclamation on the letterhead of the Union of Orthodox Rabbis of the United States and Canada restates the earlier rabbinic opposition to the Manhattan eruv and extends its language beyond Manhattan.
Its central clause says:
וכמובן שאיסור הנ״ל כולל כל עיר גדולה ואין חילוק בין מאנהעטען לעיר אחרת
It is understood that the above prohibition includes every large city, and there is no distinction between Manhattan and another city.
Rabbi Meir Greenberg is one of the sixteen names printed beneath the proclamation. Rabbi Zalman Shimon Dworkin, identified there as Av Beis Din of Lubavitch, appears on the same sheet.
The reproduced page contains printed names, not visible autograph signatures. It therefore supports saying that Rabbi Greenberg's name was printed on the proclamation, but not that the available reproduction shows his handwritten signature.
The seventy-three-name notice
Rabbi Greenberg also appears in the later seventy-three-name newspaper reproduction concerning the Flatbush eruv, where he is identified as being from Paterson, New Jersey. The notice states that an eruv was not to be established in any neighborhood of New York or Brooklyn and that carrying would remain forbidden even if one were established.
This second appearance confirms that Rabbi Greenberg's name was publicly included with the Rabbonim associated with that position. It still does not supply a separate responsum, letter, or autograph by Rabbi Greenberg himself.
For the collective ruling and its relationship to Brooklyn, Manhattan, and Rav Moshe Feinstein, see Rabbinic Proclamations Concerning Eruvin in Brooklyn and Other Large Cities and Rabbi Moshe Feinstein. Rabbi Dworkin's own position is treated on the page for Rabbi Zalman Shimon Dworkin.
