cantoresq,
while i could be wrong, i have never heard that the Rov zt”l allowed/did not object to his talmidim taking pulpits without a mechitza (although this practice was not uncommon some years ago. it is known that Rav Yakov Kaminetzky zt”l did allow some of his talmidim to take such pulpits, under very strict guidelines, i.e. they had to daven b’yichidus before the service, they should sit separately from the mixed congregation, etc.). on the other hand, the Rov’s shitta on hearing shofar on R”H from a conservative/reform shul (better to not hear shofar at all) is well known.
azi,
R’ Ilson is not a R”Y at RIETS (i believe he was offered the position but declined). he learned by the Rov for 10-15 years, and he is known amongst the Rov’s talmidim as being one of the most brilliant among them. anyone who spent time in the Rov’s shiur in the 70’s knows that the Rov thought very highly of him. he has his own yeshiva and kollel in meah shearim, so he is not as well known in the US.
