User: Give me an overview of the inspiration of the development of Barbie based on this passage
Assistant: The Barbie Doll was invented by Ruth Handler, who was inspired by a German Doll called Bild Lilli. Unlike most American dolls, which were infants, Lilli was an adult. Ruth was inspired to make a similar type of doll for her daughter because she noticed her daughter liked to give her dolls adult rolls.
