Oswald Boelcke, German captain and pilot (d. 1916)
Oswald Boelcke PlM (German: [ˈbœlkə]; 19 May 1891 – 28 October 1916) was a German flying ace of the First World War credited with 40 victories; he was one of the most influential patrol leaders and tacticians of the early years of air combat. Boelcke is honored as the father of the German fighter air force, as well as considered the "Father of Air Fighting Tactics".

Boelcke fulfilled his childhood dream of a military career by joining the Imperial German Army in July 1912. He followed his interest in aviation, learning to fly as World War I began. After duty as an observer during 1914, he became one of the original fighter pilots during 1915. He and Max Immelmann were the first German fighter pilots awarded the Pour le Mérite. When Immelmann was killed in combat in June 1916, the German high command grounded Boelcke after his 19th victory. During his month's forced grounding, he was tasked to help transform the Army's Fliegertruppe (Flying Troops) air arm into the Luftstreitkräfte (Air Force) by October 1916. His innovative turn of mind codified his combat experiences into the first ever manual of fighter tactics distributed to an air force, the Dicta Boelcke. The Dicta promulgated axioms for individual pilot success, as well as a requirement for teamwork directed by a formation's leader. Present day tactics manuals stem from the Dicta.

After a month's holiday leave spent on a military inspection tour of Turkish facilities, Boelcke was picked to lead one of Germany's first fighter squadrons, Jagdstaffel 2 (Fighter Squadron 2). By the end of the war, this squadron had 25 aces in its ranks, and four of its members became generals during World War II. During the short time before his death, Boelcke became the world's leading fighter pilot, scoring 21 more victories while commanding Jagdstaffel 2. He was killed in a crash following a midair collision on 28 October 1916. Boelcke's influence extends to the present, with extensive tributes to him at the German Air Force's Nörvenich Air Base.
