Manfred von Richthofen, German captain and pilot (b. 1892)
Manfred Albrecht Freiherr von Richthofen (German: [ˈmanfreːt fɔn ˈʁɪçthoːfn̩]; 2 May 1892 – 21 April 1918), known in English as Baron von Richthofen and popularly referred to as The Red Baron, was a fighter pilot with the German Air Force during World War I. He is considered the ace-of-aces of the war, being officially credited with 80 air combat victories.

Originally a cavalryman, Richthofen transferred to the Air Service in 1915, becoming one of the first members of fighter squadron Jagdstaffel 2 in 1916. He quickly distinguished himself as a fighter pilot, and during 1917 became the leader of Jasta 11. Later he led the larger fighter wing Jagdgeschwader 1, better known as "The Flying Circus" or "Richthofen's Circus" because of the bright colours of its aircraft, and perhaps also because of the way the unit was transferred from one area of Allied air activity to another – moving like a travelling circus, and frequently setting up in tents on improvised airfields. By 1918, Richthofen was regarded as a national hero in Germany, and respected by his enemies.

Richthofen was shot down and killed near Vaux-sur-Somme on 21 April 1918. There has been considerable discussion and debate regarding aspects of his career, especially the circumstances of his death. He remains one of the most widely known fighter pilots of all time, and has been the subject of many books, films, and other media.
