Natan as opposed to Nosson as R. Adler was known to favor Sephardic pronunciation. In a fantastic episode first reported by Prof. Shneur Leiman in the late 90’s and then addressed by Prof. Marc Shapiro about a decade later, a story of incredible hutzpah is told. The story goes back to the early 50’s and a reprinting of the Chatam Sofer’s hiddushim on shas by a publisher in the Satmar community.
Following the end of Rav Sofer’s commentary on Pesahim, a variety of material, including the practice of his rebbe, Rav Adler is included. As read (incorrectly) by Satmar, R. Adler was suggesting that Shabbat ends between 24 and 35 minutes after sunset. As devotees of the Rabbeinu Tam and even according to the Geonim, given R. Adler’s latitude, this sounds impossible. Well, what is a good hasid to do? According to Prof. Shapiro, with the Rebbe’s approval, out came the whiteout pen and the lines were obscured, never to be seen. When discovered, the rebbe insisted that all copies be destroyed; Prof. Leiman as you might suspect had a copy to display.
The paper from TheLehrhaus linked below demonstrates something embarrassing. The Satmar misunderstood what R. Adler meant, resulting in a quite unnecessary act of hutzpah.
