Virtual Tour: Turn Back the Clock
Manhattan Project oral history: Jean Bacher
Jean Dow Bachar was a human "computer" at Los Alamos during the Manhattan project.
Here, she talks about learning that her work had been used to create the atomic bombs that were dropped on Hiroshima and Nagasaki in 1945.
"What absolutely was devastating to me personally was when I suddenly realized this," she said. "I was just absolutely undone. I went home and I could not go to sleep. I just really shook all night. It was such a shock to me. So I am sure that there were others that had the same experience. But such a very deep experience, it never leaves you."
