    Historians Unmask Fourth Soviet Spy in U.S. Manhattan Nuclear Project

    Cold War sleuths have discovered a fourth Soviet spy within the United States’ atomic bomb project whose work helped the Soviet Union end Washington’s monopoly on nuclear arms, The New York Times reported Saturday.

    The Soviet Union detonated its own atomic bomb just 49 months after the U.S. detonated the world’s first atomic bomb in 1945, kicking off an arms race between the two superpowers. Soviet leader Joseph Stalin is said to have known about the U.S. Manhattan Project long before U.S. President Harry Truman was told of its existence.

    Oscar Seborer, codename Godsend, passed on sensitive information about the U.S. bomb’s design to the Soviet Union between 1944-1946 while working as an engineer at the highly-secure Manhattan Project headquarters in Los Alamos, New Mexico, The New York Times reported.

    Seborer, along with two of his brothers, had been part of a mole faction called the “Relative’s Group". “He handed over to them the formula for the ‘A’ bomb,” the study quoted.

    Seborer’s secret life showed “how widespread espionage was in the Manhattan Project,” Mark Kramer, the director of Cold War studies at Harvard University, told The New York Times.

    Seborer later defected with his family members to the Soviet Union in 1951, and died in Moscow in 2015. The FBI eventually learned of his defection and of his spy work, but kept this knowledge secret.
