Biography
Introduction
Leutnant Justus Grassmann was a World War I flying ace credited with ten aerial victories—seven enemy airplanes and three observation balloons.
Grassmann originally served with FA 32. He joined Jasta 10 at the age of 21, on 17 October 1917. He did not score his first win until 5 June 1918; however, he continued to score until November 5, just before the Armistice. He is believed to have shot down and wounded William Samuel Stephenson, (a Canadian pilot, code named "Intrepid" for his later work with British intelligence) on 28 July, ending his combat career.
