When I come to think of it, I believe Syd Hoff's books were the earliest children's books I read and enjoyed, coming very quickly after the primal "See Us Play" variety. Because of this, his clean round figures bring instant recognition of his work for me. It's personally strongly iconic, even when viewing this "adult" material from the 1940s.
Having a two-syllable full name does not hurt the recall time involved, either.
