Historian Marc B. Shapiro writes:
This burning of a Jewish book, coming so soon after the end of the Holocaust and so much at odds with the American tradition of freedom of expression, horrified both Jews and non-Jews. The fact that the excommunication and burning were covered in The New York Times only made matters worse, and everyone assumed that this was an officially sanctioned action of Agudat ha-Rabbanim…
I first saw this booklet shortly before R. Joseph Ralbag passed away. At that time he was not well and I could not schedule a time to speak with him. However, at my request R. Aryeh Ralbag asked his father some questions about the episode, and I can report the following from the late R. Joseph Ralbag. R. Ralbag did not decide on the spur of the moment to burn the siddur. Rather, he knew he was going to do this ahead of time and even discussed it with his future wife. Yet the other members of Agudat ha-Rabbanim were unaware of his plans until he lit the siddur on fire. In other words, this was an individual act by R. Ralbag and, as Agudat ha-Rabbanim would later state, it was not sanctioned by them. This testimony, from the main protagonist of the event, should finally settle the matter. (Although R. Ralbag denied burning the siddur in the telephone call referred to on the page printed above, this was obviously only said to protect himself after the controversy broke out. As indicated, hundreds of people saw him burn the siddur.
