In this episode from the Institute’s vault, we revisit an October 2007 presentation by theoretical physicist and Institute Fellow Jeremy Bernstein on J. Robert Oppenheimer, the atomic bomb, and the nuclear arms race that followed.

As a physicist, Bernstein made contributions to elementary particle physics and cosmology, working at the Institute for Advanced Study in Princeton, New York University, and Stevens Institute of Technology, where he became Professor Emeritus in 1967. He held visiting positions at CERN, Oxford, and the École Polytechnique, among others, and was the last surviving senior member of Project Orion, which studied the potential of nuclear pulse propulsion for space travel.

Bernstein was a staff writer for The New Yorker for over three decades. He wrote regularly for The New York Review of Books, The Atlantic Monthly, and Scientific American, and authored over two dozen books, including Oppenheimer: Portrait of an Enigma (2004).

He passed away on April 20th, 2025 at the age of 95. Here he is in 2007, discussing the topics on which he made a great contribution and helped illuminate.
