Jewish History

R. Gershon Henoch was a Polish Rebbe centered in the town of Radzyn. He is famous for his efforts in reinstituting the tekhelet—the blue wool mentioned in Scripture, that is to be attached to each corner of the tzitzit garment. The blue color derives from a marine creature known as the chilazon, the identity of which has been forgotten over centuries of exile. R. Gershon Henoch identified the chilazon with the cuttlefish.
