Jack Ryan, the man who made Barbie a household name in the 70's, was a full blown sex addict for a penchant for tall blonds in heels. Surprised? Meh.
From Toy Monster: The Big, Bad World of Mattel:
Ryan's friend, Stephen Gnass, confides to the author: "When Jack talked about creating Barbie . . . it was like listening to somebody talk about a sexual episode, almost like listening to a sexual pervert . . ." Ryan took calls at Mattel from a madam and patronized "high-class call girls to streetwalkers," including a "very thin and child-like" hooker. The book claims that Ryan "somehow rationalized that he was the only man in her life" until he was diagnosed with gonorrhea.
