That seems to fit even better, albeit it in a different way.
Rather than funding science to make a good contribution out of personal interest (and understanding), he could have been motivated out of a feeling of admiration, or intellectual inadequacy. Monetary funding would then appear to place him as a peer among these scientists, which would be a bit of an ego boost either way.
This would make claims about his "extraordinary group" of friends make a lot of sense. He might have associated with those people thinking that it made him feel and appear to be an interesting, intelligent, overall better person.
Seems like exactly what an "intellectual imposter" would do, more than someone trying to build a personal shield.
Besides, we all know scientists have no political influence worth harnessing.
