Lekem, (also pronounced "Lakam") an acronym for ha-Lishka le-Kishrei Mada (, Bureau of Scientific Relations), was an Israeli intelligence agency headed by spy-master Benjamain Blumberg (1957-1981), and by spy-master Rafi Eitan (1981-1986). It collected scientific and technical intelligence abroad from both open and covert sources, particularly for Israel's nuclear program. It was disbanded in 1986 following the arrest of Jonathan Pollard for espionage on behalf of Israel. Pollard was a United States Navy intelligence employee in the Naval Antiterrorist Alert Center in Washington, D.C. He was paid for delivering large amounts of classified documents to Lekem agents. Pollard was convicted and sentenced to life imprisonment.
