Missing in action of World War II

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.

Carl Frederick Zeidler (January 4, 1908 – December 11, 1942) was an American politician and the mayor of the city of Milwaukee, Wisconsin, from 1940 to 1942, winning election by unseating six-term Socialist mayor Dan Hoan. 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.

Franz Sedlacek (21 January 1891 – 1945) was an Austrian painter who belonged to the tradition known as "New Objectivity" ("neue Sachlichkeit"), an artistic movement similar to Magical Realism. At the end of the Second World War he "disappeared" as a soldier of the Wehrmacht near Toruń, Poland. He was declared missing on February 1, 1945 and pronounced dead in 1972.

Hans Kammler (26 August 1901 – 1945 [assumed]) was an SS-Obergruppenführer responsible for Nazi civil engineering projects and its top secret V-weapons program. He oversaw the construction of various Nazi concentration camps before being put in charge of the V-2 rocket and Emergency Fighter Programs towards the end of World War II. Kammler disappeared in May 1945 during the final days of the war. There has been much conjecture regarding his fate.

Eduard Deisenhofer (27 June 1909 – MIA 31 January 1945) was a German commander in the Waffen-SS of Nazi Germany. He was an early member in the SS, and served with the Leibstandarte SS Adolf Hitler and at the Dachau concentration camp in 1930s. During World War II, Deisenhofer served with several combat divisions on both the Eastern and Western fronts, earning the Knight's Cross of the Iron Cross. He held a PhD in political economy.

Isaac Campbell Kidd (March 26, 1884 – December 7, 1941) was a rear admiral in the United States Navy. He was the father of Admiral Isaac C. Kidd Jr. Kidd was killed on the bridge of USS Arizona during the Japanese attack on Pearl Harbor. The highest ranking casualty at Pearl Harbor, he became the first U.S. Navy flag officer killed in action in World War II as well as the first killed in action against any foreign enemy.
He was a posthumous recipient of his nation's highest military honor—the Medal of Honor. A Fletcher-class destroyer, Kidd (DD-661), was commissioned in his honor on April 23, 1943. The second ship named after him, Kidd (DDG-993), lead ship of four Kidd-class destroyers, was commissioned on March 27, 1981. An Arleigh Burke-class guided missile destroyer, Kidd (DDG-100), was the third ship named after him and was commissioned on June 9, 2007.
