Schacht, Hjalmar
President of economics before the war
This is the man who made Germany able to supply the money for the war.
This man caused Germany to be able to fund the war effort.
Not Guilty, Guilty, then dead
Schacht, Hjalmar was found innocent by the IMT but was later convicted by a German court and then had to serve 8 years and was freed in 1950 but died in 1970 at the age of 93. I believe that his conviction was reasonable because he didn't kill Jews or wasn't involved in the main murder of concentration camps.
