Johannes "Macki" Steinhoff (15 September 1913 – 21 February 1994) was a German Luftwaffe fighter ace of World War II, and later a senior West German Air Force officer and military commander of NATO. He played a significant role in rebuilding the post war Luftwaffe, eventually serving as chief of staff from 1966 - 1970 and then as chairman of NATO's Military Committee from 1971 - 1974.
Steinhoff was one of very few Luftwaffe pilots who survived to fly operationally through the whole of the war period 1939-45. He was also one of the highest-scoring pilots with 176 victories, and one of the first to fly the Me 262 jet fighter in combat as a member of the famous aces squadron JV 44 led by Adolf Galland. Steinhoff was decorated with both the Oak Leaves and Swords to the Knight's Cross of the Iron Cross. He played a role in the so-called Fighter Pilots Conspiracy when several senior air force officers confronted Hermann Göring late in the war.
