"Max Immelmann (21 September 1890 – 18 June 1916) PLM was the first German World War I flying ace. He was a pioneer in fighter aviation and is often mistakenly credited with the first aerial victory using a synchronized gun, which was actually performed on 15 July 1915 by German ace Kurt Wintgens. He was the first aviator to win the Pour le Mérite (colloquially known as the "Blue Max" in his honor), and was awarded it at the same time as Oswald Boelcke. His name has become attached to a common flying tactic, the Immelmann turn, and remains a byword in aviation. He is credited with 15 aerial victories." - (en.wikipedia.org 30.01.2020)
