Tzemach Atlas is correctly reporting that Rabbi Barry Gourary, the grandson of Rabbi Yosef Yitchak Schneersohn, the 6th Lubavitcher rebbe, and the nephew of Rabbi Menachem Mendel Schneerson, the 7th Lubavitcher rebbe, has passed away. He was buried this morning next to his wife in Englewood, NJ.
Many historians believe that Barry was the 6th rebbe's choice as successor and was so named in a will that allegedly disappeared from the 6th rebbe's office in the moments after the 6th rebbe passed away.
Rabbi Gourary was later the focus of a lawsuit over the ownership of his grandfather's library.
