Who gets the credit: the innovator or the implementer?

Who should get the credit? The person to came up with the idea? Or the person to did something with it?

I’m with the implementers. Thomas Edison might be remembered for the lightbulb, but Samuel Insull‘s hard work enabled everyone to have one in their homes. We also forget that it wasn’t even Edison who invented electric light (though you could argue that he perfected it). Edison was one of many who happened to have the same good idea. Insull changed society forever.
