The fact of who was first honestly does not matter: they were all amazing pioneers.
Alberto Santos Dumont created the 'Demoiselle' ( https://en.wikipedia.org/wiki/Santos-Dumont_Demoiselle)
Which was an amazing achievement for the time: It was (one of?) the first tail-plane configuration in the world. And also one of the first airplane to be mass produced.
This configuration is still used on almost all commercial airplane today and differed from the "canard" configuration of the Wright's flyer.
Even 120 years later, "La demoiselle" looks weirdly "modern" as an airplane configuration.
