Lester Jennings Hendershot (3 Giugno 1898 – 19 Aprile 1961)
Tratto dal sito Rexresearch.com
Egli teorizzò che la bussola magnetica di fatto non puntano verso il
nord e varia da nord vero in misura diversa in quasi ogni punto sulla
superficie terrestre. Inoltre, la bussola ad induzione deve essere
impostato prima di ogni volo e in quel tempo non era sempre affidabile.
Egli ha sostenuto che con un nucleo pre-magnetizzato si potrebbe
istituire un campo magnetizzato che indica il nord vero, ma non sapeva
bene come utilizzare la bussola che aveva deciso di sviluppare. Nel
continuare i suoi esperimenti, egli ha scoperto che tagliando
la stessa linea di forza magnetica nord e del sud, aveva un indicatore
del nord vero
e che tagliando il campo magnetico est e ovest,
si poteva sviluppare un movimento rotatorio
Con questo principio in mente, passò i suoi piani e ha iniziato a
lavorare su un motore che ha utilizzato questo potere magnetico. Ha
costruito uno che ruota a una velocità costante, una velocità
predeterminata quando il motore è stato costruito. Si potrebbe essere
costruito per una velocità desiderata, disse, e si sentiva che un
affidabile grado motore a velocità costante è stato uno dei più grandi
esigenze nel settore dell’aviazione in quel momento.
Quello che ha costruito sviluppava 1.800 giri al minuto. Negli anni
successivi, si rese conto che l’idea di un motore alimentato
magneticamente non era così pratico come un generatore alimentato
magneticamente, così il suo lavoro successivo è stato diretto verso il
generatore. Per evitare confusione, Va sottolineato che i primi
esperimenti iniziati un motore alimentato magneticamente, e poi un
generatore. I primi esperimenti significativi sulla versione del motore
sono tenute a Selfridge Field, Detroit, sotto la direzione di maggiore
Thomas G. Lanphier, comandante il campo e leader del gruppo Pursuit
L’apparecchio ha dimostrato a Selfridge era un piccolo modello di
quello che sperava sarebbe stato sviluppato in un motore di aereo.
Modello del generatore presentato verso la fine del 1958.
Teorie sul tema: Il campo magnetico che circonda la terra è simile al
campo magnetico generato da un uomo. Il rotore di un generatore è mosso
da alcuni mezzi di alimentazione, tagliando le linee di magnetismo, si
crea energia elettrica. La terra gira all’interno di un campo di
magnetismo. Che, non si contraddice, ma si sostiene non vi è alcun
potere per essere derivata da essa. Diciamo che abbiamo bisogno di un
meccanismo che raccoglie, polarizza e crea una connessione positiva e
negativa a questo tremendo potere che è sempre presente sulla terra .
Prendete una bussola per esempio. È possibile mantenere la est ago o
ovest, e lasciare andare, e va immediatamente a nord e sud. Questo
stesso potere, quando tagliata da un dispositivo adeguato come la terra
ruota all’interno di questo magnetismo, produrrà energia, di grande
potenza ed inesauribile. Finché la terra ruota intorno al sole, si
creerà energia elettrica.
Collection about Hendershot
name is Mark Hendershot, Lester J. Hendershot was my Father.
Lester was an inventor and in his many attempts at producing practical
items, he had a moderate success a few times with electronic toys, and
had sold some of his ideas to small manufacturers. His biggest idea,
however, was so revolutionary that it embarrassed the nation's top
scientists be-cause they couldn't explain it, and if it could be
perfected, it would possibly eliminate the need for public electric
utilities in many instances, and it would completely change most of our
present concepts of motivation.
His earlier invention was called a "motor" by the newspapers, but it
was actually a generator which was powered by the magnetic field of the
earth. His later models created enough electricity to simultaneously
light a 120 volt light bulb and a table model radio. I witnessed it
furnishing the power to run a television set and a sewing machine for
hours at a time in our living room.
It was in 1927 and 1928 that my Father began to think seriously about
this "fuel-less" generator. He had taken up flying in 1925 and he soon
realized that the ultimate development of aviation would be greatly
enhanced by the creation of an absolutely true and reliable compass,
and his first efforts were to produce such an instrument.
He theorized that the magnetic compass did not point to true north and
varies from true north to a different extent at almost every point on
the earth's surface. Also, the induction compass has to be set before
each flight and at that time was not always reliable. He claimed that
with a pre-magnetized core he could set up a magnetized field that
would indicate the true north, but he didn't know just how to utilize
that in the compass he had set out to develop.
In continuing his experiments, he found that by cutting the same line
of magnetic force north and south, he had an indicator of the true
north and that by cutting the magnetic field east and west, he could
develop a rotary motion.
With this principle in mind, he switched his plans and began working on
a motor which utilized this magnetic power. He built one that would
rotate at a constant speed, a speed pre-determined when the motor was
built. It could be built for a desired speed, he said, and he felt that
a reli-able constant speed motor was one of the greatest needs in
aviation at that time. The one he built developed 1,800 revolutions per
In the following years, he realized that the idea of a magnetically
powered motor was not as practical as a magnetically-powered generator,
so his later work was directed toward the generator.
To avoid confusion, it should be pointed out that the early experiments
began on a magnetically-powered motor, and later a generator.
The first significant experiments on the motor version were held at
Selfridge Field, Detroit, under the direction of Major Thomas G.
Lanphier, commandant of the field and leader of the First Pursuit Group.
The device demonstrated at Selfridge was a small model of what he hoped
would be developed into an airplane engine [powered by earth's magnetic
field]. Quotes in the newspapers referred to top aeronautical brass of
the day and their impressions of what they saw.
One such report was credited to William B. Stout, president of the
Stout Air Service, Inc., and designer of the all-metal type plane used
by the Ford Motor Company. Stout's comments were: "The demonstration
was very impressive. It was actually uncanny. I would like very much to
see a large model, designed to develop enough power to lift an
Major Lanphier's comments to reporters after the demonstrations were:
"The whole thing is so mysterious and startling that it has the
appearance of being a fake."
"I was extremely skeptical when I saw the first model," he continued,
"but I helped to build the second one and witnessed the winding of the
magnet. I am sure there was nothing phony about it."
My Father had first shown the military brass how his model worked, then
he supervised army technicians in building their own model, which
worked perfectly. Major Lanphier said that the electrical men to whom
they had shown the motor "... laughed at the way we wired it up and
said it wouldn't work. Then it DID work."
It was the Selfridge Field experiment which touched off the series of
stories in the national press. Stories with blaring headlines in such
papers as the Detroit Free Press, Detroit News, Detroit Times,
Pittsburgh papers, The New York Times, and many others. Most of them
tagged the instrument demonstrated at Selfridge the "miracle motor,"
and there were pictures of Major Lanphier and Col. Lindbergh, my Father
and the motor.
Anything in the news during that period which could be connected with
Lindbergh was front page whether he had an active interest, or just
happened to be in the area at the time.
Headlines in the various papers read, "Gasless Motor Tested for Lindy,"
"Lindy Inspects Fuelless Motor for Airplanes", and "Lindbergh Tries
Motor That The Earth Runs."
One story even stated that, at its request, Lindbergh and Lanphier were
flying to New York to show the motor to the Guggenheim Foundation for
the Promotion of Aeronautics.
Later reports, however, emphasized that Lindbergh actually had nothing
whatsoever to do with the experiments, and that he had just witnessed a
couple of the demonstrations as the guest of his friend, Major Lanphier.
The Selfridge tests seemed to satisfy Lanphier and his associates,
how-ever, and during the period he was there, the model the technicians
built obtained as high as 1,800 revolutions per minute and they
announced its performance was entirely satisfactory. It was estimated
these motors would run for 2,000 to 3,000 hours before the magnet
center would have to be recharged.
A man named Dr. F. W. Hochstetter, of the Hochstetter Research
Laboratories in Pittsburgh, hastily called a news conference and
displayed models of what he said were the "Hendershot Motor." He
demonstrated them, and when they wouldn't work, he declared Hendershot
was a fake, and that the motors worked only because of power derived
from concealed pencil batteries.
After he exhibited his models of the motor, Dr. Hochstetter announced
that they wouldn't generate enough electricity to, "...light a 1-volt
fire-fly" or to "...stitch a fairy's britches."
Noting the lavish lecture room in a New York hotel which had been
rented by (or for) Dr. Hochstetter for the press conference, Dr.
Hochstetter was asked [by one reporter] why he was so interested in the
Hendershot demonstrations and in trying to discredit them. He replied
merely that he had "come to expose a fraud which would be capable of
destroying faith in science for 1,000 years" and he claimed his only
motive was that "pure science might shine forth untarnished."
It was obvious to those who were pro-Hendershot that, in view of all
the fuss and bother of such a noted scientist as Dr. Hochstetter,
somewhere behind it all, someone was anxious for the innovation to be
When approached with the accusations, my Father smiled and told
reporters, "Dr. Hochstetter is correct, to a degree. I have concealed
batteries in a model or two because I found that I could not trust some
of my visitors, and I also had evidence that someone had tampered with
my work. So, I put a couple of batteries in on occasion to lead the
intruders away from what I was working on."
He added that Major Lanphier and his army technicians were proof enough
of his claims. "I didn't build the motor that was demonstrated at
Detroit," he pointed out.
"That was built by Army men under orders from Major Lanphier and under
my direction. I didn't even so much as wind the motor. They built the
motor and it works. That's my answer to all the critics—it works."
Dr. Hochstetter and his associates also claimed my Father had signed a
contract and received $25,000 for exploitation of the motor, but after
a brief period of excitement, the matter was dropped—unproven.
Not long after his demonstrations of the motor, Dr. Hochstetter died
under unusual circumstances. He was in a Baltimore and Ohio train
wreck, and he was the only passenger on the whole train who lost his
My Father was the butt of many jokes and comments at the time of the
debates about his invention. An artist, drawing for one of the
Pittsburgh papers, depicted him in a cartoon riding a propellorless
airplane. The caption made fun of him.
In later years my Father remarked, "Every time I see a jet plane go
over now, I think of that cartoon and how everyone laughed at me for
suggest-ing a plane could some day fly without a propeller. Twenty-five
years ago I tried to tell them that."
As suddenly as it all started, the publicity and sensationalism of the
Hendershot motor stopped. The last news story to appear was on March
10, 1928, when a small article appeared in most papers saying that
Lester Hendershot was a patient in Emergency Hospital in Washington.
The personal account he gave was much the same as the newspaper quote,
with the minor exception that he was it by a bolt of 220 volts, not the
jolting 2,000 the over-eager reporter had written. He was demonstrating
the motor in the patent office, and the shock paralyzed his vocal
chords, resulting in several weeks of recuperation before he completely
Something happened during this period that could explain the actions of
Dr. Hochstetter and his associates. My Father said that while he was in
the hospital, he was approached by a large corporation to stop his
activity in connection with the motor or generator.
Until the day he died, he would not reveal the name of the company,
only that if he were successful with his generator, it would be a
serious threat to their multimillion dollar industry. He named the sum
he accepted as $25,000, and the condition was that he was not to build
another unit for twenty years. That's when he dropped out of sight.
I've thought about the bizarre events connected with the generator, and
feel it is possible the "large corporation" first tried to stop the
activities through Dr. Hochstetter. When this failed, they approached
my Father personally and bought him off. It's interesting to note that
one of the doctor's charges was that he was paid $25,000 to exploit his
work. Isn't it odd that this is the same figure actually paid, but to
stop his activities, but was quoted before he was approached with the
My Father admitted that he and the family lived in constant fear, as we
were being contacted every so often by crackpots who had delved into
the records and discovered his creation, and had gone to the trouble of
searching him out. Some of them, he suspected, were representatives of
subversive groups and/or foreign powers.
This latter charge seems a little exaggerated, but was supported by a
series of letters he received from a fellow in Ohio in 1952. He had
traced my Father by going back to his hometown in Pennsylvania and
talking to my uncle about the generator.
The first letter explained that he was a part of a group of scientists
who were privately financing their own research on the same phenomena
my Father discovered in 1928. He emphasized they would not allow
backing by any organization or government since an invention such as
the Hendershot Generator should be for, "all the peoples and should not
be controlled by national governments, but should be given gratis to
the World Government when it is ready to assume World Responsibility."
He was critical of my Father for allowing the military to look at it in
That letter was written in April, and in June a postcard came with the
following terse message, "Will shortly make public via radio and
news-paper, connection your generator with 'Flying Saucer Propulsion.'
Request Security Clearance from Security Chief your group within
forty-eight hours. Have succeeded in duplication of your Generator."
In July my Father received a four-page hand-written epistle from the
Ohio man. To my knowledge, it was the last letter the writer sent on
the subject. He discussed information his intelligence had received on
flying saucers, modestly admitting his sources were better than the CIA
or the FBI, which he claimed had investigated him several times. He
intimated that a Pasadena scientist had recently been kidnapped because
he was working on an attempt to adapt the generator to aircraft.
Then he went into a long and rambling dissertation on how he got
interested in what he called the "Ether Vortex Phenomena" and the
generator. He explained that the magnetic field in the earth and
volcanic action are related, according to his studies. He had spent two
and one-half years in Japan working with Japanese volcanic scientists
on the subject.
He mentioned one study he had made, and pointed out that the shift of
the strata causing the volcano was due to a rotation of the
Electromagnetic Field of the volcano at high speeds. He urged my Father
to write a complete paper on his findings and publish them (preferably
send them to the Earthquake Research Institute in Tokyo).
Referring to a particularly bad earthquake which had just occurred in
the Los Angeles vicinity a few months before, the writer warned my
Father not to operate his generator in the area near the San Andreas
(seismic) Fault which runs through the area.
He said, "You may not believe it, but you can cause earthquake activity
to increase if you continue to operate your generator in that district.
I am wondering if you were not directly responsible for the recent
earthquake near Los Angeles?"
Then he promised that he and his associates would keep the possibility
of his involvement in the earthquake to themselves.
Letters such as these, plus occasional phone calls when the callers
would not identify themselves, and a threat from an admitted Communist
which was turned over to the FBI, caused my Father concern much of the
time. If a large organization would take over the generator and its
re-search, all he wanted out of it was enough money to take care of
himself and his family in the future years.
One of the most encouraging offers came in September of 1956 when my
Father received word that officials of the Mexican government wanted to
meet with him and discuss the possibility of using his generator for
the rural development program in Mexico.
Government officials flew to Los Angeles and drove out to our house,
where our family doctor who spoke Spanish acted as interpreter.
Arrangements were made for the family to go to Mexico City, and for my
Father to work with Mexican technicians on the generator.
We all flew to Mexico City and were housed in an apartment near the
home of the Director of Electricity. My Father supervised the Mexicans
in building a model. He had been working with them for several weeks
becoming more and more tense as time passed. He confessed to my Mother
that he was frightened because he understood no Spanish, and his fellow
workers talked constantly in little groups by themselves, often
glancing over at him. He couldn't understand a word they were saying,
and it worried him considerably.
One morning in February of 1957, the laboratory called and asked where
my Father was. My Mother told them he had left for work in the morning,
and if he wasn't there, she had no idea where he might be. She became
increasingly concerned as the day passed and there was no word from him.
That night he didn't come home, and we were on the verge of hysteria by
next morning, then we received a telegram from Los Angeles. My Father's
fear had worked itself into a nervous frenzy and he had rushed to the
airport the day before and taken a plane for California. To the day of
his death, it was a closed subject and he would never explain why he
was compelled to leave us so suddenly under such strange circumstances,
except that he feared for his life.
The final attempt to promote the generator came in the latter part of
1960 when a Dr. Lloyd E. Cannon convinced my Father that he had the
facilities to present the project to the United States Navy for
research and development.
Cannon said he was the General Manager of his own company, Force
Research of Los Angeles, Palm Springs and the Mojave Desert. Cannon
explained that his group was made up of many dedicated scientists of
various fields who contributed time and knowledge to Force Research
projects. The range of experimentation covered electronics,
astronautics, free energies, propulsion, and parapsychology.
Under my Father's supervision, two models were built and 100 copies of
a fifty-six-page "proposal" were printed for presentation to the
various government agencies and politicians who would have to review
the project for its consideration.
After the completion of the proposal and it had been sent to the
government with no results, Cannon traveled the southwestern United
States with the models trying to raise money for research. His visits
were increasingly less frequent to our home until 1961, when a tragic
climax to this story occurred.
On April 19, 1961, upon returning home from school, I found my Father
dead. It was recorded as a suicide without any further investigation.
For those who might be interested in my Father's analysis of how his
generator worked, the following are his theories on the subject:
This field of magnetism surrounding the earth is similar to the field
of magnetism in a man-made generator.
The rotor of a generator is revolved by some means of power, cutting
the lines of magnetism, creating electric power. The earth is turning
inside of a field of magnetism. That, no one contradicts, yet it is
claimed there is no power to be derived from it.
Let's say we have a mechanism that will collect, polarize and create a
positive and negative connection to this tremendous power that is
ever-present on the earth.
Take a survey compass. You can hold the needle east or west, and let go
of it, and it immediately goes north and south. This same power, when
cut by the proper apparatus as the earth rotates inside this magnetism,
will produce power, the amount of which is not calculated at this time.
As long as the earth rotates around the sun, it will create electric
power which some scientists claim does not exist. Yet, we dig into the
moun-tains for material that costs us unbelievable sums, to create the
This magnetism surrounding the earth is in the same relation to
electric power as uranium is to atomic power. Earth's magnetism is
ever-pres-ent at any height or depth. It is equal to uranium as a
by-product for power, namely electricity.
Magnetism must be cut. The lines of force circling the earth are
constant and if this force is broken up, and polarized, you have the
equivalent of uranium broken up, which creates a heat and in turn
Breaking up the forces of magnetism, polarizing them, thereby creating
a resistance for power, is the same principal as atomic energy.
Scientists claim it requires friction to generate electricity. I claim
the earth rotating as it does, according to scientific theory, creates
friction as a generator. The ever-present magnetism is the field, or
We have only to utilize this source of power to light every home,
high-way, bridge, airplane or any type of thing that cannot now be
lighted because of inadequacy of present facilities.
A very small unit composed of wire, a magnet, several especially
designed coils, condensers, collector units, and a few other minor
items, will cut this force. Another especially designed mechanism will
polarize it, giving a positive and a negative connection to any
resistance and the result is the generation of electricity.
There you have the theory of how to create electricity from the
magnetic force of the earth, as written by a man with only a high
As years went by I've always wanted to continue with my Father's
invention, but have worried myself about possibly running into the same
problems my Father did.
It would not do my Father justice just to stop all work on it and now I
am ready to fulfill his dream. Since childhood I have been fascinated
by electricity and have spent over twenty-six years in the electrical
Of his three sons, I alone have pursued this fascination and have
applied my knowledge and experience to carry on my Father's work.
