Writer, Prix Goncourt in 1958 (1906-1997) Francis Walder is the pen-name of Francis Waldburger who was born in Brussels. He trained to be an army officer at the Belgian Royal Military Academy and was captured by the Germans during the invasion of Belgium in 1940 and imprisoned in Germany until 1945. On his release, he became a representative of former prisoners-of-war in the peace negotiations. He continued to serve as an army officer until his retirement, when he began to write essays, novels and philosophical works. His novel Saint-Germain ou la négotiation won the Prix Goncourt in 1958 and was made into a film by Gérard Corbiau in 2003. The novel recreates the delicate negotiations between the Catholic King and the Protestant huguenots which resulted in the short-lived Peace of Saint-Germain-en-Laye in 1570. His other well-known novels are Une lettre de Voiture (1962) which recounts the adventures of a seventeenth-century courtier and Chaillot ou la co-existance (1987) which is set amid the intrigues of the court of Louis XIII and Cardinal Richelieu.
