The male doll counterpart to Mattel's Barbie doll has an official, albeit fictional, full name of Ken Carson. Ken has no middle name, and his eponym Ken Handler, is the son of Barbie and Ken creator Ruth Handler. Ken's fictional birth date is March 11, 1961, though the doll has managed to maintain his youthful appearance over the years.
