Was Bleriot the real disigner of the planes that bear his name or more a businessman and test pilot?
"
Louis Peyret, who had unsuccessfully attempted to fly the Blériot III floatplane and had designed the Blériot VI, a tandem wing aircraft, was a friend of Louis Blériot."

It appears that the real designer of Bleriot VI, a plane that flew over 100 meters many times during the interval July - September 1907, was Louis Peyret and Bleriot just financed the project and acted as a test pilot, much like Farman and Delagrange who ordered planes to the Voisin brothers and after that flew them.
