The Ken doll was introduced in 1961 by Mattel as the counterpart to Barbie. He was created by Elliot Handler. The first Ken doll didn’t have bendable arms, his head could only turn left and right, and his hair was made from felt. In 1977, the Ken doll came out with bendable arms, a head that could turn, plastic hair, and more muscular. Like Barbie and her occupations, Ken has had over 40. His full name is Kenneth Sean Carson.
