The Cadbury family’s idyllic factory village in Birmingham, England—where these bars were created in 1897—helped inspire Milton S. Hershey’s own facility in Pennsylvania. “It was a sort of social utopia,” explains Deborah Cadbury, a family descendant and author of Chocolate Wars. “The Cadbury brothers as Quakers were the first to really look after their employees and provide pensions and security of employment and a living wage.” Although the Cadburys no longer own the company, its influence still looms large: its Dairy Milk and 5-Star bars are some of the world’s best-selling confections.
