Ben-Ami Kadish (September 2, 1923 – July 16, 2012) was a former U.S. Army mechanical engineer. He pleaded guilty in December 2008 to being an "unregistered agent for Israel," and admitted to disclosing classified U.S. documents to Israel in the 1980s. His unauthorized disclosure of classified U.S. secrets to Israel was concurrent with the espionage activity of Jonathan Pollard, who was convicted of espionage and answered to the same Israeli handler.
Ben-Ami Kadish was born in Connecticut but grew up in what was the British Mandate of Palestine. As a young man he fought with the Haganah. He also served in both the British and American military during World War II. Kadish graduated from Northeastern University with a degree in Mechanical Engineering. When he retired in January 1990, Kadish was a supervisory engineer in the Fuze Division of the Army Armament Research, Development and Engineering Center.
He resided with his wife Dorris in a Monroe Township, Middlesex County, New Jersey retirement community. Ben-Ami Kadish died at University Medical Center of Princeton, Plainsboro and was interred in Beth Israel Cemetery, Woodbridge.
Kadish was employed as a mechanical engineer by the United States Army Armament Research, Development and Engineering Center at the Picatinny Arsenal in Dover, New Jersey from October 1963 to January 1990. Kadish conspired to disclose national defense-related documents to Israel and worked as an agent of the Israeli government from 1979 to 1985. Kadish took classified documents to his handler's home in Riverdale, Bronx several times (including information about nuclear weapons, a modified F-15 fighter, and the Patriot missiles) and let an unnamed Israeli government worker take photographs of them.
