On December 24, 1906, at 9 P.M. eastern
standard time, Reginald Fessenden
transmitted human voices from Brant Rock near
Boston, Massachusetts to several ships at
sea owned by the United Fruit Company
Fessenden could truly lay claim to be the
inventor of radio and he fully expected the
world to beat a path to his door. Instead, he never
received his due recognition,
lost control of his patents and the ensuing revenue
which made other inventors and
companies immensely wealthy
