The Blue Max Airmen series is the real story of the German airmen awarded the Pour le Mérite during the Great War. Author Lance J. Bronnenkant, PhD., and Aeronaut Books are pleased to bring you the most detailed and graphically lavish account of these heroes ever produced, covering the men in context with the war’s chronology of events. For each recipient a comprehensive, well-illustrated biography of the man is given, together with photos of the aircraft he flew, followed by details of his service, including other awards won. Color profiles of the aircraft are also provided for interest to enthusiasts and as references for modelers. Volume 4 covers Rudolf Berthold, Gustav Leffers, Albert Dossenbach, and Hans Berr, the tenth through thirteenth aviation recipients of the Pour le Mérite. Volume 4 includes 140 photographs, 6 of them in color, and 14 color profiles of aircraft flown by these aces in its 112 pages.
