Henry Morgenthau (1891-1967) was President Roosevelt's Secretary of the Treasury from 1934 until the end of the war. Morgenthau's father came from Mannheim in Germany.

At the Quebec Conference of September 1944 Morgenthau put forward a plan to settle the fate of Germany after the war. The Morgenthau Plan would turn Germany into an agrarian country, in which most industry would be dismantled. 

This plan actually had the support of Churchill and Roosevelt but not of their Cabinets. So when the plan become public they abandoned it quickly. .
