Werner Mölders (18 March 1913 – 22 November 1941) was a World War II German Luftwaffe pilot, wing commander, and the leading German fighter ace in the Spanish Civil War. He became the first pilot in aviation history to claim 100 aerial victories—that is, 100 aerial combat encounters resulting in the destruction of the enemy aircraft—and was highly decorated for his achievements. Mölders was instrumental in the development of new fighter tactics that led to the finger-four formation. He died in an air crash in which he was a passenger.
