In 1896...Guglielmo Marconi gave the
first public demonstration of radio at Toynbee Hall, London.
In 1901...Marconi sends first Atlantic
wireless transmission
Italian physicist and radio pioneer
Guglielmo Marconi succeeds in sending the first radio transmission
across the Atlantic Ocean, disproving detractors who told him that
the curvature of the earth would limit transmission to 200 miles or
less. The message--simply the Morse-code signal for the letter
"s"--traveled more than 2,000 miles from Poldhu in
Cornwall, England, to Signal Hill in Newfoundland, Canada.
Born in Bologna, Italy, in 1874 to an
Italian father and an Irish mother, Marconi studied physics and
became interested in the transmission of radio waves after learning
of the experiments of the German physicist Heinrich Hertz. He began
his own experiments in Bologna beginning in 1894 and soon succeeded
in sending a radio signal over a distance of 1.5 miles. Receiving
little encouragement for his experiments in Italy, he went to England
in 1896. He formed a wireless telegraph company and soon was sending
transmissions from distances farther than 10 miles. In 1899, he
succeeded in sending a transmission across the English Channel. That
year, he also equipped two U.S. ships to report to New York
newspapers on the progress of the America's Cup yacht race. That
successful endeavor aroused widespread interest in Marconi and his
wireless company.

Marconi's greatest achievement came on
December 12, 1901, when he received a message sent from England at
St. John's, Newfoundland. The transatlantic transmission won him
worldwide fame. Ironically, detractors of the project were correct
when they declared that radio waves would not follow the curvature of
the earth, as Marconi believed. In fact, Marconi's transatlantic
radio signal had been headed into space when it was reflected off the
ionosphere and bounced back down toward Canada. Much remained to be
learned about the laws of the radio wave and the role of the
atmosphere in radio transmissions, and Marconi would continue to play
a leading role in radio discoveries and innovations during the next
three decades.
In 1909, he was jointly awarded the
Nobel Prize in physics with the German radio innovator Ferdinand
Braun. After successfully sending radio transmissions from points as
far away as England and Australia, Marconi turned his energy to
experimenting with shorter, more powerful radio waves. He died in
1937, and on the day of his funeral all British Broadcasting
Corporation (BBC) stations were silent for two minutes in tribute to
his contributions to the development of radio.
In 1915...Legendary singer Frank Sinatra, dubbed "Ol' Blue Eyes" and the "Chairman of the Board," was born. He died May 14, 1998 at 82.

In 1957...KEX, Portland, Oregon Disc Jockey Al Priddy, was fired for playing Elvis Presley's rendition of "White Christmas." He violated the radio station's ban against the song. The station had banned Presley’s interpretations of Christmas carols, believing that such a sexually-charged performer had no business recording religious music.
In 1961...Ham radio satellite Oscar 1
was launched with military Discoverer 36
In 1971...David Sarnoff, who founded the National Broadcasting Company (NBC) and throughout most of his career led the Radio Corporation of America (RCA), died at age 80.

In 1995...the CBC (Canadian
Broadcasting Corporation) announced the Radio Canada International
service would end on March 31.
In 2003...Unkle Roger McCall, a long-time DJ
on WCMF-FM, Rochester, New York, was fatally wounded by a gunshot in
a robbery attempt. His killer has never been brought to justice.
In 2008...Spike O'Dell did his last
broadcast on WGN-AM. He spent 21 years with the station, 8 of them
doing mornings.
In 2012...Veteran broadcaster (KABC-Los Angeles, KLAC-Los Angeles, KIEV-Los Angeles, KGIL-Los Angeles, KING-Seattle) Ray Briem, who ruled the Los Angeles overnight airwaves with his radio talk show for 27 years (1967-1994), died of cancer at 82.
