What Happened To Boris Pash After Oppenheimer

Being a large biographical movie, Oppenheimer had a large cast of real people who came in and out of J. Robert Oppenheimer’s life, one of whom was a military intelligence officer named Boris Pash. Christopher Nolan’s 2023 film, Oppenheimer, tells the story of an American scientist, J. Robert Oppenheimer, and his involvement with the creation of the atomic bomb that destroyed Hiroshima and Nagasaki in Japan during World War II. Throughout his life, Oppenheimer was involved in many professional and personal relationships before and after his infamous trial, one of whom was Boris Pash, an officer, and interrogator.

Throughout his life, as depicted in the movie, one aspect that was questioned was Oppenheimer’s connections to communism. Although Oppenheimer himself was not a Communist, he did not shy away from their company, as depicted in the movie, through his extramarital affair with Jean Tatlock. As seen in the movie, Colonel Pash was sent to investigate Oppenheimer and his staff for potential Soviet espionage and communist connections; his testimony played a role in Oppenheimer’s disgrace in the public eye, as seen at the end of the movie.

Boris Pash Testified Against Oppenheimer In The Security Hearing

Colonel Pash was born Boris Theodore Pashkovsky in San Francisco, California, to Russian parents. Both Pash and his father served in the Russian army during World War I before he returned to the U.S. and joined the Military Reserve in 1930. He also served as the head of the Alsos Mission, focusing on German nuclear energy in 1943.

Pash played a role in coordinating the safety of America’s nuclear projects; he investigated the rumors of espionage at the University of California where Oppenheimer was working on the Manhattan Project at the Radiation Laboratory in 1943. Pash disliked Oppenheimer, suspecting he could be a spy for the Communist Party, but ultimately, despite Pash’s protests, Oppenheimer was allowed to stay working on the project. Ten years later, he testified about his investigation of Oppenheimer in the hearing and recounted his initial beliefs about the scientist’s connections to communism and espionage; it was revealed that while Oppenheimer did not commit espionage, he did fail to report a case, that was known as the Chevalier Incident, which further damaged his reputation.
