Early proposals of wireless telegraphy in Spain: Francisco Salva Campillo (1751-1828)

摘要

Francisco Salva Campillo read in December 16th, 1795 before the Academy of Sciences in Barcelona the paper "On the application of electricity to telegraphy". This is probably one of the first suggestions on the possibility of wireless telegraphy, as it is recorded in the first books written about the history of wireless. An account of Salva's contributions to telegraphy and his proposal of wireless telegraphy is presented.
