Yosef Lishansky
Yosef Lishansky (Hebrew: יוסף לישנסקי; 1890 – 16 December 1917) was a Jewish paramilitary and a spy for the British in Ottoman Palestine. Upon his arrival in Palestine, Lishansky sought to join HaShomer but, denied membership, he founded a rival organization, HaMagen. Several years later, he joined the Jewish espionage organization, Nili. Lishansky was wanted by the Ottomans for his activities and was betrayed by HaShomer when he sought refuge with them. He escaped capture several times, but was eventually caught and sentenced to death in Damascus.
