Feyman, I believe.
It wasn't Feynman. This prof never was one of the famous ones and I'll be damned if I can remember his name. He was one of the many junior physicists on the staff. The one story that sticks out in my mind was the calculation department. There were several mathameticians who broke down the equations into a series of additions and subtractions, which were then given to an army of female clerks operating the old mechanical adding machines. The only computers were tied up calculating ballistic trajectories for the Army and Navy. AS each clerk finished her assignment, it was given back to the mathametician for further integration. He said the noise in those old Quonset huts was deafening.
