The Austrian Edmund Sparmann was a technical genius from an early age. During the First World War he worked as a designer and test pilot at Albatroswerke, later Phönixwerke. He came to Sweden in the summer of 1919 with two Phoenix aircraft, the fighter aircraft Phönix D.III and the two-seater reconnaissance aircraft Phönix C.I, later popularly called Dront. Flygkompaniet and later, Flygvapnet had these two types in service for many years built on a license. Sparmann later became employed at Centrala Flygverkstaden on Malmen as a designer and test pilot. In 1933 he started Ing. E. Sparmann's Aircraft Workshop at Lilla Essingen in Stockholm. There he designed and built the aircraft he became best known for, the Sparmann S 1 - the Sparmann fighter. The book describes Sparmann's life, his constructions and of course the whole story of the little Sparmann hunter. As usual when it comes to Mikael's books, it contains lots of unique and fantastic photographs, but also many drawings of, above all, Sparmann S-1, but also some interesting documents in facsimile
