The Biden administration is reversing a 1954 determination that revoked J. Robert Oppenheimer, referred to as the daddy of the atomic bomb, of his safety clearance and finally ended his profession as a physicist.

The famed physicist grew to become one of many world’s main researchers in theoretical physics — and have become an integral determine within the creation of the atomic bomb throughout World War II — but later arose suspicion on account of his affiliation with progressive causes and opposition to growing the hydrogen bomb.

During the height of anti-communist hysteria in the 1950s, the Atomic Energy Commission, which preceded the Department of Energy, launched an investigation that stripped Oppenheimer of his safety clearance. The 1954 determination irreversibly broken his profession.

But now the Department of Energy is revoking its earlier determination — calling the investigation a “flawed process that violated the Commission’s own regulations,” Secretary of Energy Jennifer Granholm mentioned in a press release on Friday.

“As time has passed, more evidence has come to light of the bias and unfairness of the process that Dr. Oppenheimer was subjected to while the evidence of his loyalty and love of country have only been further affirmed,” Granholm mentioned.

The determination comes after a long time of lobbying from the scientific group to clear Oppenheimer’s status.

“History matters and what was done to Oppenheimer in 1954 was a travesty, a black mark on the honor of the nation,” Kai Bird, co-author of the Oppenheimer biography American Prometheus, told The New York Times. “Students of American history will now be able to read the last chapter and see that what was done to Oppenheimer in that kangaroo court proceeding was not the last word.”

Granholm mentioned the Department of Energy can also be reversing the choice due to a “responsibility to correct the historical record and honor Dr. Oppenheimer’s profound contributions to our national defense and the scientific enterprise at large.”

Oppenheimer died in 1967. A new film about the famed physicist, titled Oppenheimer, is scheduled to hit screens in July.
