In 1963 with the introduction of Midge Hadley (Barbie doll's friend), Allan Sherwood was being designed. Allan was conceived for three important reasons. First and foremost to target the "shared clothes" ideal with Ken, second for the double dating possibilities and lastly as a "buddy" to Ken. Mattel introduced Allan in the1964 along with Skipper, Barbie's sister. Allan was advertised as Ken's buddy and as Midge's boyfriend. He was quickly discontinued in 1965 the year the second version was released, but was available for sale in limited quantities until 1966
Not only is Allan Ken doll's first male friend, he is the only male friend to date to be given a last name (Sherwood). Allan; (and Midge®) are the only married characters in the Barbie doll line. Allan was named after Barbara Handler's husband Allan Segal, whom she married when she was only 19.
