Manfred Albrecht Freiherr von Richthofen (German: [ˈmanfreːt fɔn ˈʁɪçthoːfn̩]; 2 May 1892 – 21 April 1918), known in English as Baron von Richthofen or 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 I, 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 Entente 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 over France near Vaux-sur-Somme on 21 April 1918. Richthofen never married and had no known children. 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, usually with his Red Baron moniker and flying his signature red Fokker Dr.I.

Name and nicknames Richthofen was a Freiherr (literally "Free Lord"), a title of nobility often translated as "baron".[1][2] That is not a given name or strictly a hereditary title since all male members of the family were entitled to it, even during the lifetime of their father.[a] Richthofen painted his aircraft red, which, combined with his title, led to him being called the "Red Baron" ("der Rote Baron"ⓘ), both inside and outside Germany.[1] During his lifetime, he was more frequently described in German as Der Rote Kampfflieger. That was variously translated as "The Red Battle Flyer" or "The Red Fighter Pilot" and was the name used as the title of Richthofen's 1917 autobiography.[3]
