cantoresq – you sound like a lawyer
Midwesterner – My father’s brother was also childless. I think The Steipler was in to collect for the book but am not positive. My uncle heard about him and told my dad. They both had several children afterward (my oldest brother is 54) and are mentioned in the “thank yous” in his sefer. My father knew he gave the money to “a talmid chochom” and filed the sefer away. 25 years later a cousin noticed their names in the sefer and asked them about it. My dad was shocked! He had never put 2 and 2 together in regard to who The Steipler was, and who’s book he donated to. I have it at the house, you are welcome to see it. Has his signature too!
When my daughter went to his kever last week she said she thought about the fact that she wouldn’t exist if not for his bracha.
