Dear Avira,
This is all fuzzy research. Asking uncles who hock too much and aunts who think they have a better memory.
Some points. Fallsberg claims to a Bais Hatalmud creation. And Sav Elya Ber does not call himself a talmid of Rav Aaron.
Stamford moved to Monsey or near it. I’m not sure if it’s similar to what it was. I do not know who the money was, but it definitely was not Rav Meir. And I’m not sure he would know much about who Rav Aaron honored or didn’t.
Obviously, Rav Chaim Epstein’s yeshiva is a good a source as there is for Rav Aaron’s opinions. But I’m still guessing off of what I gathered from hearsay. I have no source that this is intentional to any of them.
When I started asking, I thought I would get more chessed organizations. But it was too conflicting. Like people who were born into not frum families that stayed close to the Jewish communities. Or the wealthy that used their wealth on others, but were not otherwise noteworthy role models.
