[Haskell-cafe] historical question about Haskell and Haskell Curry

We always say that Haskell is named for Haskell Curry because his work provided the logical/computational foundations for the language. How exactly is this the case? Specifically, does anyone claim that Curry's combinatorial logic is more relevant to the theoretical foundations of Haskell than e.g. Church's lambda calculus? If not, why isn't Haskell called "Alonzo"? ;-) Mike
