Karl Jatho
Karl Jatho (February 3, 1873 - December 8, 1933) was a German pioneer and inventor, performer and public servant of the city of Hanover.
Allegedly, on August 18, 1903 he flew with his self-made motored gliding airplane 4 months before the first flight of the Wright Brothers, but it is claimed still two years later than Gustave Whitehead. His first attempts he made with a plane having three lifting surfaces, but switched to two surfaces soon. They were modelled after the Zanonia seed, a seed that was known for its gliding capability. In contrast to the Wright Brother's planes, the wings were flat in profile and not curved.
The plane was equipped with a single-cylinder 10 hp Buchet engine driving a two-bladed pusher propeller and made hops of up to 200 ft, flying up to 10 ft high.
He founded a flying school and a plane factory.
