The Wireless: - ANSWER Using simple Morse code, Italian inventor Guglielmo Marconi
developed the first wireless telegraph in 1895. Marconi reasoned that just as wire could
carry electrical charges, so could Hertzian waves, later referred to as radio waves.
Nipkow Disc: - ANSWER The device consisted of a rapidly rotating disc placed between
a scene and a light-sensitive selenium element. A beam of light shining through the spiral
perforations as the disc revolved caused pinpoints of light to perform a rapid scanning
movement over the object in front of it, something like the movement of eyes back and
forth across a printed page.
Audion Tube - ANSWER This glass-bulb detector (or receiver) of radio waves was also
capable of amplifying and even generating radio waves
Guglielmo Marconi - ANSWER Owner the Wall Street offices of American Marconi,
needed a personal messenger aka Sarnoff
Who was the German engineering student that discovered television's scanning system and
patents world's first mechanical television system called BLANK Disc? - ANSWER Paul
Nipkow; Nipkow Disc
Who was the Canadian who achieved limited success with experiments in wireless voice
transmission? - ANSWER Aubrey Fessenden
Who develops the Audion tube for voice transmission with amplified sound -
ANSWER Lee de Forest

, According to Life Magazine's special millennium publication, selecting the top 100 events in
the lat millennium, what was the number one event? And why was it considered the top
event of the millennium? - ANSWER The printing press was the number one event.
This new thirst led inventors to seek a way to mass-produce the written word.
Who developed the first wireless telegraph in 1895? - ANSWER Guglielmo Marconi
Which country was the first to capitalize on Marconi's new means of communication? -
ANSWER British Empire
What invention (created in 1884) established a scanning technique as a step toward
transmitting images? - ANSWER Nipkow Disc
In 1901, who sent out the first long-distance wireless message (from Cornwall, England to St.
John's, Newfoundland, Canada)? And what was the message sent? - ANSWER Marconi
and the message said "s"
Competing with Marconi, the inventor focused on transmitting continuous sound (rather
than the interrupted wave bursts of Morse code), his ideas becoming fundamental for radio.
What is the inventor's name? - ANSWER Aubrey Fessenden
This glass-bulb detector (or receiver) of radio waves was also capable of amplifying and even
generating radio waves. What was the name of this invention? And who invented it? -
ANSWER The audion tube, invented by Lee de Forest
In 1908, Lee de Forest broadcast a human voice atop a world famous landmark. What was
the name of the landmark, and the city where it's located? - ANSWER Eiffel Tower
located in Paris
