not according to a Google search and what I remember learning.

The prolific American inventor Lee De Forest (1873-1961) is one of several
pioneers of radio development. De Forest experimented with receiving
long-distance radio signals and in 1907 patented an electronic device named
the audion. Until this time, the radion was considered little more than
"wireless telagraphy," since it sent Morse code (dots and dashes) instead of
conveying actual sound. **De Forest's new three-electrode (triode) vacuum
tube** boosted radio waves as they were received and made possible what was
then called "wireless telephony," which allowed the human voice, music, or
any broadcast signal to be heard loud and clear.

Invention is a fuzzy subject, though, and most countries can claim different 
people invented the same thing. In the days of communism, Russia's Radio 
Moscow claimed that everything had a Russian inventor, for example.
