VosIzNeias is reporting that Rabbi Avrohom Blumenkrantz has passed away. Rabbi Blumenkrantz was known for his Passover guides, in which he occasionally championed extreme positions, including an attempt several years ago to ban the use of Styrofoam plates, cups, bowls, etc., even for year-round use, based on his understanding of the halakhot surrounding their production, which involves minute amounts of non-kosher ingredients.
Rabbi Blumenkrantz passed away from complications of diabetes.
UPDATE: The funeral will be tomorrow morning, Friday, at 9:30 a.m. at Rav Blumenkrantz's synagogue in Far Rockaway, 827 Cornaga Avenue.
