1940s missing person cases

Antoine Marie Jean-Baptiste Roger, comte de Saint-Exupéry, known simply as Antoine de Saint-Exupéry (UK: , US: , French: [ɑ̃twan də sɛ̃t‿ɛɡzypeʁi]; 29 June 1900 – 31 July 1944), was a French writer, poet, journalist and pioneering aviator. He received several prestigious literary awards for his novella The Little Prince (Le Petit Prince) and for his lyrical aviation writings, including Wind, Sand and Stars and Night Flight (Vol de nuit). They were translated into many languages.
Saint-Exupéry was a successful commercial pilot before World War II, working airmail routes in Europe, Africa, and South America. He joined the French Air Force at the start of the war, flying reconnaissance missions until France's armistice with Germany in 1940. After being demobilised by the French Air Force, he travelled to the United States to help persuade its government to enter the war against Nazi Germany.

Saint-Exupéry spent 28 months in the United States of America, during which he wrote three of his most important works, then joined the Free French Air Force in North Africa, even though he was far past the maximum age for such pilots and in declining health. He disappeared and is believed to have died while on a reconnaissance mission from the French island of Corsica over the Mediterranean on 31 July 1944. Although the wreckage of his plane was discovered off the coast of Marseille in 2000, the ultimate cause of the crash remains unknown.

After just two years in office Zeidler resigned his position as mayor to enlist in the United States Navy Reserve to fight in World War II. His merchant marine ship and all hands were lost off the coast of South Africa in December 1942.
