•
1890s - By 1890, Stubblefield reportedly was using
these methods to transmit and receive
understandable human voice. He was reportedly the
first to use a loudspeaker with his telephone
(needs citation). Lochte has argued that when
Stubblefield spoke of "wireless" telephony in the
1880s he merely meant his acoustic telephone, which
could operate with non-electric cord, cat-gut or
banjo strings.
•
1890s - Stubblefield vocational trade school -
founded in 1890, called "The Nathan Stubblefield
Industrial School,"
"Teléph-on-délgreen" on the 85 acre
land that is now the campus of Murray State
University. (Lochte) MORE TIMELINE ON FAMILY AND

•
1890t - Working with these high voltages, Tesla
discovers the best insulation by immersion in oil.
Also at this time he discovers the workings of
fluorescent gas filled tubes, since observers said
that he had fluorescent tubes around his laboratory
worked by "wireless power", i.e. from a high
voltage cable loop around the laboratory. He even
invented an X-ray lamp taking photos of the bones
in his hand, but never claimed a patent for it.
During this period he was hosting dinner parties
and afterwards would take his guests back to his
laboratory giving demonstrations of high voltage
electricity, producing flaming discharges that
leapt across the width of his laboratory,
accompanied by the smell of sulphurous fumes. He
wowed observers and reporters with seemingly death
defying demonstrations, passing hundreds of
thousand volts at high frequency with low currents
through his body, lighting a carbon button lamp,
which he held. Very high temperatures were created
in the vacuous globe vaporizing the carbon into a
gas.
•
1890
- Congress passes the Sherman Antitrust Act,
on July 2, which
outlaws trusts and combinations in restraint of
trade and establishes fines for violators. The law
remains in effect today.

1891s
01 - Both Nathan's schools, the Nathan B.
Stubblefield Industrial School and the
Teléph-on-délgreen Institute, were
built on Capt. Billy's 85 acre original
Stubblefield farmland, now the campus of Murray
State University. The University was founded by
Rainey T. Wells, one Nathan's first students. The
School was training installers. -MORE PHOTO OF

•
1891s
01- Nathan Stubblefield perfected induction aerial
coil. What made
the induction coil so sensible, was the broadcaster
didn't need the required tall 100' mast tower, and
extraneous motor (generator) system to supply the
high voltage current needed to power their
induction coils to produce the RF spark signals
emitted in space.
•
1891t - A set of experiments, on what Tesla called
"a simpler device" for the production of electric
oscillations, resulted in the device known today as
the Tesla Coil. A Tesla Coil is a transformer made
up of two parts - a primary and secondary coil, one
inside the other. When electrically charged the
interaction between the two coils produces a
voltage high enough to make the air conduct
electric currents. Getting the power high enough to
make the air an effective conductor of currents is
key to wireless transmission of radio waves. Tesla
pursued the application of his coil technology to
radio. By tuning a coil to a specific frequency he
showed that the radio signal could be greatly
magnified through resonant action. However, before
he was able to fully demonstrate sending a radio
signal 50 miles, his laboratory and equipment were
destroyed in a fire. Thus, when Marconi made his
famous 1901 Trans-Atlantic transmission, the power
portion of his system was based on Tesla's
findings. In fact, Tesla and Marconi remained in
legal battles for patent priority even after both
men died.
•
1891t
- Tesla becomes a naturalized citizen of the United
States at the age of
35,
on July 30,
1891. He
establishes his 35 South Fifth Avenue laboratory in
New York during this same year. Later, Tesla would
establish his Houston Street laboratory in New York
at 46 E. Houston Street. He lit vacuum tubes
wirelessly at both of the New York locations,
providing evidence for the potential of wireless
power transmission.
•
1891t 02 - On February 21, 1891, Tesla publishes
his article "Phenomena of alternate currents of
very high frequency" in Electrical World, Vol.
XVII, No. 8".
•
1891t 02- On February 4, 1891, Tesla applies for a
patent for the production of high frequency
currents by means of a condenser discharge.

•
1892 - Edison had organized his various businesses
into the Edison General Electric Company. As the
consumer electricity industry expanded, it became
increasingly difficult for competitors to produce a
complete electrical installation relying solely on
their own technology. - INDEX NEW YORK VS KENTUCKY
Believe it or not, in the days of Edison, before
wireless telephony was renamed "Radio," the word
"phony" -- bothered everyone in the wireless,
especially those in the motor - electric generator
industry like Tesla, Edison and Westinghouse.
Nathan's first experiments in the EMW started with
a compass and loadstones.
•
1892
- General Electric Company

01 - First Wireless Telephone Broadcasting
Demonstrations: (Voice) Nathan B. Stubblefield's
first public "wireless telephone" demonstrations
were given in the town square of Murray,
Kentucky.
By connecting his
telephone apparatus to his newly invented
electrolytic coil earth battery -- he transmitted
and detected continuous undamped electromagnetic
waves, at a radius of about one half mile; Using
his grounded bare wired aerial system connected to
his loop coil antenna, placed on top of his
receiver -- he was able to talk back and forth
"without wires" to others with a like telephone and
loop antenna, or broadcast voice and music to those
listening through a mono-earphone piece; Rainey T.
Wells, who later became the founder and president
of Murray State University, was one of the first
persons to hear Stubblefield's wireless voice
transmissions. Rainey became his assistant in the

1892s
01 - NBS. First permanent wireless telephone
broadcasting installation.
Teléph-on-délgreen Industrial
School,
was the first permanent wireless telephone
broadcasting installation in the world, (the
precursor to AM
Radio). The
transmitter and receivers were usually placed 200
feet apart for demonstrations. The electromagnetic
coils were also the precursor for today's
"Firewire" and battery operated implants in today's
world of broadband streaming video and
electro/heartstimulus technology.The station was
constructed in Murray, Kentucky, U.S.A. in January,
1892. The School operated in conjunction with
Stubblefield's Murray Court Square drug
store/telephone facilities.
Teléph-on-délgreen Industrial School
is now the campus of Murray State University,
founded by Rainey T. Wells. What is the Relevancy
of Stubblefield's wireless telephone to the
Internet? It is tantamount to the EMW theory that
operates today's wireless Lap Tops, Palms, PDCs,
WI-FI "HotSpots" and Bluetooth systems. They can
all be linked to a local wired telephone or cable
TV exchange using a modem or a router; Modems
connected to the telephone line, provide Digital to
Audio conversions to allow computers to connect
over the telephone network.
•
1892s 02 - The Nathan Stubblefield Telephone
Manufacturing Co., was the first permanent wired
telephone exchange switchboard installation in
Murray on February 12, 1894. The telephone service
was constructed in the town square to work in
conjunction with Stubblefield's wireless telephone
operation. His mechanical telephone (patented
1888), was enabled to transmit voice without wires
in 1892. Transmissions were created from grounded
electromagnetic wave energy connected to his
aerial, then transmitted through the atmosphere to
a companion receiver. What is the Relevancy of

1893 - The World's Columbian Exposition takes place
in Chicago. The Rockefellers attend.
•
1893t
- At the 1893 World's Fair, the World's Columbian
Exposition in Chicago, Illinois, an international
exposition was held which for the first time
devoted a building to electrical exhibits. It was a
historic event as Tesla and George Westinghouse
introduced visitors to AC power by using it to
illuminate the Exposition.
On display were
Tesla's fluorescent lights and single node bulbs.
Tesla also explained the principles of the rotating
magnetic field and induction motor by demonstrating
how to make an egg made of copper stand on end in
his demonstration of the device he constructed
known as the "Egg of Columbus." • • The
successful lighting of the Expo was then a factor
in Westinghouse winning the contract to install the
first hydroelectric power machinery at Niagara
Falls. All of the enormous motors at the power
station bore Tesla's name and patent numbers.
•
1893t - From 1893 to 1895, Tesla investigated high
frequency alternating currents. He generated AC of
one million volts using a conical Tesla coil and
investigated the skin effect in conductors,
designed tuned circuits, invented a machine for
inducing sleep, cordless gas discharge lamps, and
transmitted electromagnetic energy without wires,
effectively building the first radio
transmitter.
•
1893t - From 1893 to 1898, Tesla protects by
patents his various discoveries in the field of
high frequency currents, including a large number
of oscillators with an ingenious device for
extinguishing the sparks.
•
1893t - In St. Louis, Missouri, Tesla made a

•
1894 - Dies: Heinrich Hertz, (1857-1894), on
January 1, in Bonn, Germany at the age of 37.
•
1894 - Radio waves were known as 'Hertzian Waves'
when Marconi began experimenting in 1894. A few
years earlier Heinrich Hertz had produced and
detected the waves across his laboratory. Marconi's
achievement was to produce and detect the waves
over long distances, laying the foundations for
what today we know as radio
•
1894 - Wireless telegraphy using damped high
frequency radio waves was demonstrated in 1894 by
Sir Oliver Lodge, but that system could carry voice
messages or music (see Radio article).
•
1894m - Guglielmo Marconi, the wealthy young
Italian man, just in his 20s, read an account of
Heinrich Hertz's discovery of electro-magnetic
waves, in an electric journal his mother had
pointed out.
•••
The spark hit, his vacation was cut short, and he
rushed back to his home-lab facilities, to test the
sparkling ideas that had struck him.
•
1894m
- Marconi first experiments with Hertzian
Waves.

1894t - In 1894, Tesla erects his first small radio
station in his laboratory and begins his
experiments in radio technology. At the same time,
he builds his first radio-controlled automata.
•
1894t
- Tesla became very close friends with Mark Twain
and they spent a lot of time together in his lab
and elsewhere.
Tesla was also friends
with Robert Underwood Johnson. He had amicable
relations with, among others, Francis Marion
Crawford, Stanford White, Fritz Lowenstein, George
Scherff, and Kenneth Swezey, but he remained bitter
towards Edison. The day after Edison died the New
York Times contained extensive coverage of Edison's
life, with the only negative opinion coming from
Tesla who was quoted as saying, "He had no hobby,
cared for no sort of amusement of any kind and
lived in utter disregard of the most elementary
rules of hygiene" and that, "His method was
inefficient in the extreme, for an immense ground
had to be covered to get anything at all unless
blind chance intervened and, at first, I was almost
a sorry witness of his doings, knowing that just a
little theory and calculation would have saved him
90 per cent of the labor. But he had a veritable
contempt for book learning and mathematical
knowledge, trusting himself entirely to his
inventor's instinct and practical American
sense."

•
1895m - Marconi succeeds in signaling dit dahs.
•
1895m
- Wireless Telegraph Demonstration: (dit dahs - no
voice) across Marconi's the family estate at
Pontecchio, Italy, - a distance of about 1.2
miles.
In the spring of 1895,
what Nathan B. Stubblefield did with wireless voice
transmission in 1892, Guglielmo Marconi did with
dots and dashes utilizing damped electromagnetic
waves emitted by his Ruhmkorff coils. (See 1897);
He discovered that his "black box" utilizing the
Ruhmkorff coil, could send controlled messages, by
touching two electrically charged wires together in
a dit dah manner - over distances far greater than
those from his villa to the garden -- distances
which would travel more than a mile. It was
Marconi's great basic invention.
•••
Like Stubblefield, Marconi built an aerial -- an
antenna which he connected to one side of the spark
gap; (Hertz had merely used a horizontal rod ending
in a plate.) The aerial was a metal cylinder atop a
pole. He connected the other side of the spark gap
to a ground (at first, a copper plate lying in the
ground). The receiver also had an aerial and
ground; The signals were too weak so Marconi
connects the oscillator to antenna and ground to
increase power. It was Marconi's great basic
invention. Like Stubblefield, he built an aerial --
an antenna which he connected to one side of the
spark gap.
•
1895t - On March 13, 1895, fire destroys Tesla's
laboratory with the radio station, the constructed
automata, his first models of induction motors and
other polyphase system devices as well as a
valuable technical archive.
•
1895s - Nathan Stubblefield. In 1895, Nathan
getting prepared to file for Patent for his
coil-soil energy Batteries. The patent would become
the premise for the exact, distinct and separate
EMW soil science. It was his theory that if he
could create several small green valleys of WiFi
hot spots within his 85 acre
Teléph-on-délgreen, each hot spot
could become a static electricity storage bin that
would produce enough undampened EMW currents to
charge his electrolytic batteries. The cause of the
EMW force could then create enough electricity to
electrify both, a land-line telephony system, as
well as his new mobile wireless telephony
system.
•
1895t - Tesla and Edison became adversaries in part
due to Edison's promotion of direct current (DC)
for electric power distribution over the more
efficient alternating current advocated by Tesla
and Westinghouse. Until Tesla invented the
induction motor, AC 's advantages for long distance
high voltage transmission were counterbalanced by
the inability to operate motors on AC. As a result
of the "War of Currents," Edison and Westinghouse
were almost bankrupt.
•
1895t - Tesla in 1895 lost everything when his
laboratory went up in smoke. Friends including Mr.
Adams, a banking associate of J.P. Morgan, helped
him set up a new laboratory in Houston Street, New
York with a grant of $40,000. It took him two years
to rebuild the radio system from his head, which he
then patented, but was unable to persuade anyone to
invest in his ideas. He staged an impressive
demonstration in Madison Square Gardens, where he
had a large tank of water on which floated a boat.
He directed its movement by remote radio control.
He even managed to get the boat to submerge still
controlling its underwater movement. He claimed he
could design a remote controlled submarine torpedo
boat, but the U.S. Navy never took him up the idea.
He was experimenting with very high voltages for
the time, and had the vision of transmitting power
through the air i.e. without wires. This tended to
give him a bad name with other engineers and the
technical press. They were uncertain of taking his
wild predictions seriously.
•
1895t - The hydro-electric station was commissioned
on April 20th 1895 with three water driven
alternators each of 5,000 HP. Although not getting
any financial reward, Tesla was acclaimed for his
inventiveness and feted at dinners given in his
honor.

1896s
1026 - PATENT FILED: Electricity from Earth Patent
Filed, October 26, 1896. Nathan B. Stubblefield's
Earth Coils produced continuous electromagnetic
energy (EMF) emitted from the earth. The Patent
was issued on March 8, 1898. An array of his coils
placed around his transmitter, was the precursor to
the AM Radio tower; The transmitter and receiving
tower were usually placed 200 feet apart for
demonstrations held at Stubblefield's
Teléph-on-délgreen Industrial School
or at Murray's Court Square. The towers at the
School were 100 feet high. The small coils are also
the precursor for today's electro/heart stimulus
technology. What is the Relevancy of the earth
battery to the Internet? See
1898-1905.
•
1896s - Motor. The NBS low power - motor, induction
coil low-voltage concept was first used by
Stubblefield to demonstrate how electrical power
could be extracted from the earth to operate in his
1892 to 1886, NBS Industrial School Projects.

1896t - Still experimenting with resonance in 1896,
he created a small earthquake. At this time Tesla
published the complete description of the
Tesla/Thomson coil in electrical journals (Elect.
Review 1896), which was described as a high
frequency, high voltage (10,000 &endash; 15,000
volts) transformer with no iron core. By 1899 Tesla
was running short of money again and a dangerous
situation was developing with such high voltages
wafting around a confined laboratory. This shook
buildings in a radius of a dozen square blocks, so
that the rumbles reached the local police station,
and a squad of policemen was dispatched to his
laboratory. They arrived there only to find that he
had smashed the offending equipment with a
sledgehammer.
