Whose idea was it to give the president a veto?

The presidential veto was a part of the original Constitution written by the Founding Fathers. Although the constitution does not state that the President has veto powers, the President has to sign legislation into law. This in effect is a veto. However if the President does not sign into law a piece of legislation within 10 days then he is constitutionally required to send it back to Congress with his objections in writing.
