What is the smartest human in the Marvel Universe's greatest invention?

Rad-D or the Universal Entropy Gun.

I don't have a clue to what his best invention is, but I read Future Foundation recently and I thought it was pretty awesome how Richards help Dr. Doom regain his brain functions, which resulted in Doom being able to use magic again.
