I'm curious to read more about this. What was the name of this Standard Oil head who was murdered? I did a quick Google search with the info you provided, but I didn't find anything.
FWIW, it's said that Henry Ford of Ford Motors had lobbied FDR during the war with an unusual request. Because US Army bombers were built at some of his factories, Willow Run and others, he didn't want 'his' bombers to strike factories in Germany that he also owned. I don't know how the White House replied to that, but it might have been something like 'Be fruitful and multiply', but not in those exact words.
I can not trace the name. However the details were mentioned in the Autobiography of a WWII secret agent I read some years ago. He was actually a Canadian national. He was a pioneer in the development of radio communication locating and put away quite a number of German spies. Anyhow he detailed these events.
It is well known that Standard Oil were helping the Nazis.
[Despite powerful efforts of the Rockefeller interests and the nation’s capitalist press to put a lid on the truth, damning evidence continues to pile up about the Standard Oil-I.G. Farbenindustrie conspiracy.
Last week, tire Truman Senate Investigating Committee heard further government testimony showing that Standard Oil, in conformity with its arrangements with the Nazi interests, continued as late as December 1941 to provide oil and other necessary operating supplies for Nazi and Italian airlines bringing “spies, propaganda and profit-producing goods” to South America and returning to Europe with “essential war materials.”
The committee heard from the lips of a leading Treasury official the details of Standard’s efforts to turn over its Hungarian plants to the Nazis for $24,000.000 gold, a deal which the Treasury blocked because it would have “permitted the Standard Oil Co. to have been preferred by Germany over other American owners of capital investments in Germany” and would have furthered Nazi economic conquest in Europe.
These facts further brought out the close tie-up between Standard and the German capitalist interests and lent additional weight to the documentary evidence presented to the Truman Committee two weeks ago by Assistant. Attorney General Arnold, which established that Standard and I.G. Farben had an iron-clad cartel agreement, first made in Nov. 1929 to recognize each other’s exclusive rights in particular economic spheres. I.G. Farben was to have world control in chemicals and Standard, in petroleum products and synthetic gasoline.]
But according to the author the guy met his end at the hands of the British Secret service under Churchill's orders. I suspect this is an event the British government and agencies are reluctant to publicize.
