Drexel Sprecher was educated at the University of Wisconsin, the London School of Economics, and at the Harvard School of Law before receiving a position at the US Government's Labor Board in 1938. He enlisted in the American military after the United States declared war on Germany, and was posted to London. After the war, Sprecher served as a prosecutor of Nazi war criminals at the Nuremberg trials.
An architect whose name I forget now, who worked for OSS, was pushed in very early and he immediately came up with the design and it required knocking out some walls and to make the courtroom larger so there'd be room for the press and for visitors.

Every bit of the trial was recorded on tape, so that there could never be any argument about what was said.
