Where did the term "Doubting Thomas" orignate?

The term 'a "Doubting Thomas'" is a direct reference to the biblical story of the apostle Thomas, who refused to believe that the resurrected Jesus had been seen by the other apostles until he could actually see and feel the wounds Jesus received during his crucifixion.

Thomas, one of the twelve, called Didymus, was not with them when Jesus came.The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe.

And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you. Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God.

Jesus saith unto him, "Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed".
