The family name in the title of the chewing-gum company founded by William Wrigley Jr. in 1891 is Wrigley.
William Wrigley Jr. established the company in Chicago after beginning his career selling soap and baking powder. He used chewing gum as a promotional incentive for customers, and the gum eventually became the main business. The company became especially associated with brands such as Juicy Fruit, Spearmint and Doublemint.
Wrigley was a family business for much of its history. Members of the Wrigley family held leadership roles across several generations, including William Wrigley Jr.'s son, Philip K. Wrigley. In 2008, Mars, Incorporated acquired the Wrigley business, ending its status as an independent family-controlled company.
A common mix-up is confusing the Wrigley company with Wrigley Field, the Chicago baseball stadium. The stadium was named after William Wrigley Jr., who owned the Chicago Cubs, but it is not the company itself.
