Lekem, (also pronounced "Lakam") an acronym for ha-Lishka le-Kishrei Mada (Hebrew: הלשכה לקשרי מדע‎, Bureau of Scientific Relations), was an Israeli intelligence agency headed by Benjamin Blumberg (1957–1981), and 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.
