Leslie Groves was always my favorite.
THE most important man in the Manhattan Project (imo).
The guy who built the Pentagon on time and under budget
In a course I took at Defense Acquisition University the instructor told the following anecdote about Leslie Groves' leadership of the Manhattan Project.
The construction of the uranium enrichment apparatus at Oak Ridge required massive amounts electricity (almost 10% of the total US electric grid at the time if I recall correctly) and they needed some massive transformers that were built on site. The engineers realized that the copper wire used for the transformers was in very high demand for the war effort for almost every piece of electrically powered technology as well as for things as mundane as brass shell casings and copper jacketed bullets. They went to Groves and told him how much copper they needed to draw it into hundreds of miles of wire. Groves asked them if there were potential substitutes for copper and they said that gold would also work very well.
Groves went to Treasury Secretary Henry Morgenthau and told him that he needed to borrow some gold from from Fort Knox for the Manhattan Project. Groves had a letter from FDR that he could use with any government official that basically said, "give General Groves whatever he needs." Morgenthau was happy to oblige and asked how much gold he needed. Groves told him, 25,000 pounds. Morgenthau didn't blink but asked if he could convert that into Troy ounces since that was how they counted the gold reserves. It was about 364,000 Troy ounces.
Groves took a locomotive with a box car and a lot of armed security from Oak Ridge to Ft Knox and made the withdrawal of gold ingots and returned to Oak Ridge. The gold was carefully drawn into wire and used to make the windings for the transformers. All shavings and trimmings were carefully collected and saved. After the war, the gold wound transformers were disassembled and the gold was melted down and cast back into ingots and returned to Ft. Knox. The amount of gold returned to Ft Knox was 99.98% of the initial withdrawal.
