Thanks for pointing this out. I knew it, but the uniqueness had not been clear. He is an intriguing character and an anomaly in so many ways, and I would say that is because, in large part, of his relationship with his mother, whom he befuddled (like so many others in his life), but she nonetheless adored him.
A strong-willed mother can be found behind many famous people. Or at least that was one of the findings in https://www.amazon.com/Cradles-Eminence-Childhoods-Famous-Wo.... (A book I'm familiar with because my mother read it and applied its lessons in odd ways to her parenting..)
That is why on general principle I would expect his mother to likely be a cause for his success.
