Einstein was not very good with math. He stood on the shoulders of Pointcaré, Lorentz, and Riemman. He saw more, he saw farther, he was brilliant, but I'm not sure he'd have done what he did without those shoulders to stand on. OTOH, once he had Special Relativity in the bag and saw an outline of General Relativity, he had the persistence to see it through. Feynman had it easier in this sense: more shoulders to stand on, less radical theories to develop, and was less alone in terms of peers. IMO Feynman and Einstein are comparable.
