The marketing director of McDonald’s took Urie Bronfenbrenner’s Human Development course.  When she shared her plan to creating a “burglar” concept for marketing the hamburgers, he argued against this idea and suggested she emphasize a “family” theme.  She revised the plan and sent Bronfenbrenner two life-size original Ronald McDonald dolls to get his opinion.  These dolls (or at least one of them) remained in his office for years.
