Everybody seems to know the name Marconi. They often think of him as the inventor who started the idea and technology of radio.
While Marconi is often credited as being “the”, or at least, “a” father of radio, he was in fact experimenting with wireless telegraphy, not radio. In fact, Marconi was never interested in transmitting voice and didn’t think it possible. Nor is it even certain he actually heard the Morse clicks from across the ocean amid the static on Dec 01, 1901. His spark technology meanwhile was also a dead end and he would abandon it in 1912.
At the same time, it was a Canadian working for the US Weather service was developing actual radio technology,
Real radio broadcast one year before Marconi’s telegraph clicks
Reginald Fessenden, convinced that Marconi’s ‘spark’ technology was a dead-end, had been working on his own theory of wireless transmission called amplitude modulation, a technology that we would later know as AM radio.
It was on this day, December 23, 1900, a year before Marconi’s claimed telegraphy clicks, that he transmitted the very first wireless radio voice message to become the real “father” of radio.
He sent a message a distance of 1.6 kilometres between two 13-metre towers. The first words ever transmitted were, “One Two Three Four — is it snowing where you are Mr. Thiessen? If it is, telegraph back to me”.
Thiessen quickly telegraphed back using Morse code that he heard Fessenden clearly and that it was indeed snowing.
Continuing to perfect his technology, on Christmas eve 1906, he made the world’s first public broadcast.
From his station near Boston, ships at sea in the Atlantic and Caribbean outfitted with his recievers heard a female vocalist and Fessenden himself playing ‘O Holy Night’ on his violin. He also sings carols,and read passages from the Bible.
Fessenden is credited with over 500 patents and inventions from sonar, to television, to a fathometer to tracer bullets and many more. He died in 1932.
