The Emile de Schepper and Hubert Hagens “Helpman I” monoplane was exhibited in the bicycle school of Fongers in Groningen (Netherlands) in May 1911. It had an open fuselage aft of the pilot seat and triangular-section fuselage and was powered by a 5-cylinder Anzani, rated at 50 hp. The monoplane was designed and built by Emile de Schepper and Hubert Hagens. Hagens was the mechanician of the famous Belgian flyer Jan Olieslagers and Emile de Schepper was the son of the Belgian E. J. de Schepper, who was a wealthy billiard manufacturer in Helpman (a separate village then, now a part of the town Groningen), hence the name “Helpman I”.
