Louis Slotin, a little-known Canadian, helped build the real-life atomic bombs portrayed in ‘Oppenheimer’

Canadian scientist Louis Slotin of Winnipeg helped build the world's first atomic bombs that were dropped on Japan in 1945. Slotin was a key part of the top secret "Manhattan Project" in Los Alamos, New Mexico in 1945. (Photo courtesy of the Jewish Heritage Centre of Western Canada).

In one of the summer’s buzziest blockbuster films—Oppenheimer, about the real-life head of the top-secret wartime Manhattan Project—the film’s director neglected to include an important Canadian figure.

A Jewish scientist from Winnipeg, Louis Slotin was a key part of the team of groundbreaking researchers at the Los Alamos atomic laboratories. He helped build and assemble the bombs that would be dropped on Japan in 1945, ultimately ending the Second World War.

Slotin’s family thought he was researching medical uses for nuclear radiography. They only learned the truth after he was killed in a controversial experiment after the war had ended. Slotin received an immense—and fatal—dose of radiation, but not before he heroically saved everyone else in the room by separating unstable plutonium pieces with his bare hands. Slotin died in Los Alamos in 1946 at age 35.

On The CJN Daily, Slotin’s surviving Canadian relatives Beth Shore and Rael Ludwig both of Winnipeg, join to tell their uncle’s story, in hopes the world will learn more about what Oppenheimer overlooked.
