J.Herris German Aircraft of Minor Manufacturers in WW1. Vol I (A Centennial Perspective on Great War Airplanes 49)

Grade

   Hans Grade was born on 17 May 1879 and died on 22 October 1946. He graduated from an engineering high school in Berlin and while studying established a small workshop where he built racing motorcycles. Becoming interested in aviation he built a light triplane in 1907 that was powered by an air-cooled V-6 engine of his own design that delivered 36 horsepower. Tested on the military exercise field at Magdeburg, Grade adjusted his machine until he flew a distance of 60 metres, the officially designated first powered flight in Germany.
