Halpern's father Hennoch Halpern was an Austro-Hungarian and a prominent Zionist prior to the First World War, working with David Ben-Gurion and Moshe Sharett. He emigrated to the US in 1909, where he remained involved in Zionist causes until his death in 1965.
He served as Executive Assistant to the Deputy Director for Plans for seven years. He retired in December 1974.According to Seymour Hersh, Halpern "was under seemingly constant investigation" by James Angleton because of his Jewish background.
- "Jim looked at me real hard," Halpern recalled with a laugh, "but I told him, 'I'm not going to muck up your desk.' The Israelis never approached me."
At the inaugural meeting of the Consortium for the Study of Intelligence in April 1979, Halpern presented an essay on clandestine collection (spying) which argued, in Roy Godson's summary, that "collection capabilities had been seriously damaged by the Freedom of Information Act, the Congress, and the attitudes and guidelines adopted by recent Directors of Central Intelligence.
