Abandonment of Nussach

Yanky55 you obviously know very little about Kwartin. The words meant a great deal to him, and it is apparent in his work. In fact when he heard Tiher R. Yishmael, the Gerrer Rebbe excplained that it’s impossible to sing that piece and not have hirhurei teshuva. I suggest you read his autobiography, Meine Leben, to learn more about him.

Yanky55 I haven’t read the entire book, but I did once spend a couple of hours in the library skimming through it. As to Kwartin’s personal religious observances, I hvae no idea what he did in his private life. But I do know that his son, Saul Kwartin, was a life long member of Agudath Shalom in Stamford CT, an Orthodox schul, and he walked to schul, even when many his age drove there. I never heard anything about Kwartin’s reputation, so I can’t address your question.
