Philippe Mottu is a Swiss diplomat, author and activist born on 9 October 1913 in Geneva; he died in Lonay (Vaud) on 23 August 2010.
In 1946, inspired by the American Frank Buchman, he was instrumental in the acquisition of the former Caux Palace Hotel, a dilapidated hotel above Montreux, Switzerland, by a group of about 100 Swiss, in order to create an international conference centre at the service of European reconciliation and reconstruction.
He wrote a dozen of books of political and social philosophy.
