Inventors/Inventions

Lee De Forest

“Father of Radio”
Invented the “Audion” - forerunner to the vacuum tube and was able to transmit voice. Adding an element that allowed easier reception and more amplification of sound, was the discovery that would push the growth of radio.
A series of experiments in 1907 led to:
Broadcasting concerts enjoyed by ship operators & other wireless enthusiasts.
He and his wife broadcast music from the top of the Eiffel Tower over a distance of 500 miles.
Began daily music broadcasts in 1916.
His transmitter was located on the High Bridge in the Bronx, he broadcast the election returns on Nov. 7, 1916.
Stated Charles Evans Hughes had defeated Woodrow Wilson, which was an error. But, the spectacle of broadcasting important news was impressive.

Charles David “Doc” Herrold

Opened a broadcasting school in 1909.
Built an antenna on the roof of the Garden City Bank Building that was so large, wires spread from the 7 story building to the tops of several adjoining buildings.
Began regularly scheduled, weekly ½ hour news and music program which was made a daily program in 1910.
His wife, Sybil may have been the first woman to broadcast her own show, a musical program for young people.
Herrold claimed to be the 1st “broadcaster” because he aimed his programs at the widest possible audience and he offered the 1st regular programming.
His 15 watt station, with call letters FN, then SJN, became KQW in 1921, and finally KCBS in 1949 (San Francisco).

Transmission of Sound

Sound was made more powerful through the invention of the carbon transmitter.
1877 – Music transmitted over the phone from NYC to Sarasota Springs, NY was accidentially heard in Boston and Providence.
Electricity had leaked to other trunk lines & the waves were inducted through the air.
This proved that sound waves could be set in motion & that they could be detected or received.
