Au-delà de l'horizon by P. Demerseman, R. Foster.
A few months after Marconi succeeded in a transatlantic wireless communication, Kennelly in the United-States and Heaviside in England published the hypothesis of an ionospheric reflecting layer to explain the propagation of radio waves beyond the skyline. About twenty-two years later, Appleton realized the very first experiments, with the help of an interference method, proving the existence of such a layer and estimating its distance from the ground. Only two years laters, Breit and Tuve, using a pulsed radiowaves method obtained similar data. The scientific careers of these physicists are also briefly reviewed.
