Walter Nowotny, Austrian-German soldier and pilot (b. 1920)
Walter Nowotny (7 December 1920 – 8 November 1944) was an Austrian-born fighter ace of the Luftwaffe in World War II. He is credited with 258 aerial victories—that is, 258 aerial combat encounters resulting in the destruction of the enemy aircraft—in 442 combat missions. Nowotny achieved 255 of these victories on the Eastern Front and three while flying one of the first jet fighters, the Messerschmitt Me 262, in the Defense of the Reich. He scored most of his victories in the Focke-Wulf Fw 190, and approximately 50 in the Messerschmitt Bf 109. Nowotny scored an "ace in a day" on multiple occasions, shooting down at least five airplanes on the same day, including two occurrences of "double-ace in a day" (scored at least ten kills) in the summer of 1943.

Nowotny joined the Luftwaffe in 1939 and completed his fighter pilot training in 1941, after which he was posted to Jagdgeschwader 54 "Grünherz" (JG 54) on the Eastern Front. Nowotny was the first pilot to achieve 250 victories – 194 in 1943 alone – earning him the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds on 19 October 1943. For propaganda reasons, he was ordered to cease operational flying.

Reinstated to front-line service in September 1944, Nowotny tested and developed tactics for the Messerschmitt Me 262 jet fighter. He was credited with three victories in this aircraft type before being killed in a crash following combat with United States Army Air Forces (USAAF) fighters on 8 November 1944. It is thought his engine might have failed. After his death, the first operational jet fighter wing, Jagdgeschwader 7 "Nowotny", was named in his honour.
