Felicity Loudon, granddaughter of Egbert Cadbury, smiles as she looks at a book entitled 'Cadbury's Purple Reign: The Story Behind Chocolate's Best Loved Brand' during an interview with Reuters at her home in London, November 5, 2009. It's perhaps understandable that Loudon bristles at the thought of British chocolate maker Cadbury potentially falling into the hands of U.S. foods giant Kraft. As a member of the fourth generation of the founding family, Loudon remembers her grandfather's efforts to develop a caring and benevolent company, values she attributes to the family's Quaker roots.
