Dayyan in London; locally known as "Rabbi Aryeh Loeb"; born at Krotoschin, in the grand duchy of Posen, in 1797; died in London Feb. 10, 1878. For many years his father had been head of the "bet din" of his native place; and he himself was a pupil of the eminent rabbi Akiba Eger of Posen. Jointly with Rabbi Aaron, Barnett discharged the duties of dayyan in London for nearly half a century, causing him to become one of the best-known figures in the London community. He was a rabbi of the Orthodox stamp, and an earnest student of the Talmud. About five years before his death he was stricken with blindness.
