All right: another hint . He was the director of the REICHSBANK, the Minister of Economy in the 30s and AH's "economy wonder man" because he saved the Mark after the inflation. He did not precisely kill anybody, but his money allowed the Nazis to go to war. He was wrongly accused on July 20th 1944 to be part of the plot and fell in disgrace , but in fact he had taken his distances with the Regime before the war.
