My mother shared this with me many times over the years. My Grandfather was assigned to the Pentagon during WWII in appropriations. Why an architect was assigned to appropriations always puzzled him. One day this request for a major amount came across his desk. Due to the amount, my grandfather wanted to know what it was for. No one would tell him. He went to lunch with a co-worker and mentioned the requisition. When he got back from lunch, men in black suits came to see him. They asked him if he'd gone to lunch at X place, he said yes. Did you discuss this requisition with Y, the person he went with. They told he wasn't to do that again. He asked them what was the requisition for, they said they couldn't tell him. He said he wouldn't approve it until he knew what it was for. They said he was to sign it by order of the President. My grandfather pushed back and said not until he knew what it was for. Again he was told to sign it by order of the President. So he said ok and signed it Jack Franklin by order of the President. You've probably guessed, it was for the Manhattan Project.
