ANSWER
Barbie's full name is Barbie Millicent Roberts.
The Mattel company began in 1945 when Ruth and Elliot Handler and Harold "Matt" Matson formed a company to make picture frames. As a side business they began making dollhouse furniture with the leftover scraps of wood. In short time Matson sold out, and the Handlers turned the focus of the company to making toys. In 1959 Ruth Handler developed the Barbie doll, inspired by her daughter Barbara's love of playing with cut-out paper dolls. Originally Mattel had no need for a last name for Barbie; that came about when Golden Books (Random House) began publishing a series of Barbie books under license from Mattel.
In case you were wondering, Ken's last name is Carson.
