Manhattan Project: J Robert Oppenheimer

Naomi Alderman explores the multifaceted mind of J Robert Oppenheimer, scientific lead on the Manhattan Project, a vast, top secret scheme to build the world's first atomic bombs in World War II.

The Project was a remarkable feat of human intellect with a real, devastating human cost. It required close cooperation between the US military and a group of world-leading scientists. In many ways, Oppenheimer was a puzzling candidate for the job. He was brilliant, but fuelled by self-loathing. A physicist, he was also a student of philosophy and mysticism, interested in left-wing radical politics. Oppenheimer built the bomb, but later called the weapon's industry "the devil's work". His legacy, like the Manhattan Project itself, is infinitely complex.
