The Ditchley Foundation based at Ditchley Park near Chipping Norton, Oxfordshire, was established as a privately-funded charity in 1958 by philanthropist Sir David Wills. Moved to act by painful memories of the Second World War and the dangers of the Cold War, Sir David Wills' founded Ditchley to support the Transatlantic Alliance between the United States and Europe by bringing decision makers and experts together in a unique and inspiring setting.
Ditchley connects people to talk through complex problems in support of peace, freedom and order. The Foundation works towards a more dependable, open and connected world by bringing a unique mix of people from the worlds of politics, technology, finance, academia, the media, the arts and more to build new common ground so that we can move toward solutions to global challenges.
The current director is James Arroyo OBE, previously director for data at the British Foreign and Commonwealth Office, charged with adapting the organisation to the digital age. Sister organisations, American and Canadian Ditchley, help to shape the conference programme as well as select American and Canadian participants. The full programme, subsequent Director's notes, news items and other publications are posted on the Foundation's website.
