I'd like to second Kelly Johnson to be added to this list.
But Donovan Berlin, Alexander Kartveli, Jiro Horikoshi and Reginald Mitchell at least need an honorable mention.
What are the criteria for most succesful?
Whereas the original list appears to be based in part on the number of designs, IMHO success might be based on a single one - which is in a class of its own.
In a way a truly inspired and revolutionary design might not be a success, while it might lead to more successful designs.
