| Loomis
As early as August 15, 1858, an American dentist name Mahlon Loomis was
beginning a series of experiments in wireless telegraphy within the state
of Ohio! With the interruption of the American Civil War, Loomis continued
his work. In October of 1866 he sent signals between two mountaintops,
about 15 miles apart, in the Blue Ridge Mountains. Senator Samuel Pomeroy
of Kansas and Representative John Bingham of Ohio were present at this
demonstration. Both men later gave much support on Loomis' behalf in the
U.S. Congress.
In January of 1869, Senator Charles Sumner of Massachusetts introduced
a bill into Congress to appropriate $50,000 (well over a million dollars
in present-day purchasing power) for development of Loomis' system. This
bill languished in committee for two years, at which time Rep. Bingham
introduced a bill to incorporate the Loomis Aerial Telegraph Company,
giving it the right to issue up to two million dollars worth of stock.
This bill stated that no money was to come from the U.S. Government (one
of the reasons the original bill was stalled in committee).
In early 1873, President Grant signed the bill into law, and a few
months later, on July 20, 1873, Loomis was granted U.S. Patent 129,971 for
the invention of his system. Unfortunately, Loomis' company had gone
bankrupt during the stock market panic of 1869, and he was never able to
garner enough financial support to put the system into operation.
Although Loomis died in 1886, he left his mark in other areas. He was
not only an inventor in the area of radio, but he also held a number of
patents in the field of dentistry, including methods of making false teeth
and specialized filling materials and methods. Some of his ideas are still
being used today
Patent Disputes
There are certain things to be noted about these early inventors. The
first is that during this time period, patent offices would issue patents
on working items only, either full-sized or models. Thus, Loomis, Dolbear,
and the others had to actually demonstrate that their equipment worked!
There was not patenting of ideas at that time.
Next, although most of the people involved were university types, they
did not publish papers to the extent that papers are published today.
Also, there was a lot of nationalism involved with something of such
possible importance as communicating without wires.
Marconi had established a consortium of powerful British investors.
Several of these were members of Parliament, and the rest were in a
position to command the ear of that governing body. Because of this, both
Lodge and Fessenden (Canada being a member of the British Commonwealth)
were effectively silenced by governmental actions. The Marconi Company
soon dominated the wireless (radio) scene.
From about 1900 until 9143, there were a large number of patent rights
battles in the courts of the United States and Great Britain. Little by
little, Marconi's patent empire was voided until, just before his death in
1943, his latest patent was vacated in favor of Nikola Tesla.
In fact, Marconi's list of patent fights included almost all of the
inventors and pioneers of radio communications. People like deForest,
Fleming, and others were in an almost constant fight with Marconi and his
company. Because of these lengthy patent battles, the British Government
did not wish to aid those fighting against the British-based Marconi
Company. Therefore, they insisted that Marconi was the inventor of radio.
It is unfortunate that this misconception is still being taught today.
Marconi, through the efforts of his British company, did more than
anyone else to commercialized radio. However, he really did nothing
himself in the actual invention of the systems. Everything he used was
invented by someone else, and was actually used in tow-way radio
communications before Marconi. In Loomis' case, the patent was issued
before Marconi was even born!
Because the history books of the early 20th Century taught
that Marconi was the inventor of radio, it is still being taught today.
This is unfortunate, for there were, in reality, several true inventors
(each with a different system type) who were communicating before him. But
such is the work of the history text writer.
There are other such tales about grossly wrong history texts, but these
can wait for another time
Here is a transcript of Loomis' patent, which describes a means of
wireless communication using induced or sympathetic currents/voltages
between similar towers. The electrical transient that occurs when a
base-insulated, statically charged tower is switched to ground creates a
measurable disturbance at the base insulator of a second tower located
several miles distant. What we would say today is that this transient
contains DC and AC components, or DC and RF.

Improvement in Telegraphing
Specifications forming part of Letters Patent No. 129,971, dated July
30, 1872
To all whom it may concern:
Be it known that I, Mahlon Loomis, dentist, of Washington, District of
Columbia, have invented or discovered a new and Improved Mode of
Telegraphing and of Generating Light, Heat, and Motive-Power; and I do
hereby declare that the following is a full description thereof.
The nature of my invention or discovery consists, in general terms, of
utilizing natural electricity and establishing an electrical current or
circuit for telegraphic and other purposes without the aid of wires,
artificial batteries, or cables to form such electrical circuit, and yet
communicate from one continent of the globe to another.
To enable others skilled in electrical science to make use of my
discovery, I will proceed to describe the arrangements and mode of
operation.
As in dispensing with the double wire, (which was first used in
telegraphing,) and making use of but one, substituting the earth instead
of a wire to form one-half the circuit and the continuous electrical
element far above the earth's surface for the other part of the circuit. I
also dispense with all artificial batteries, but use the free electricity
of the atmosphere, co-operating with that of the earth, to supply the
electrical dynamic force or current for telegraphing and for other useful
purposes, such as light, heat and motive power.
As atmospheric electricity is found more and more abundant when
moisture, clouds, heated currents of air, and other dissipating influences
are left below and a greater altitude attained, my plan is to seek as high
an elevation as practical on the tops of high mountains, and thus
penetrate or establish electrical connection with the atmospheric stratum
or ocean overlying local disturbances. Upon these mountaintops I erect
suitable towers and apparatus to attract the electricity, or, in other
words, to disturb the electrical equilibrium, and thus obtain a current of
electricity, or shocks or pulsations, which traverse or disturb the
positive electrical body of the atmosphere above and between two given
points by communicating it to the negative electrical body in the earth
below, to form the electrical circuit.
I deem it expedient to use an insulated wire or conductor as forming a
part of the local apparatus and for conducting the electricity down to the
foot of the mountain, or as far away as my be convenient for the telegraph
office, or to utilize it for other purposes.
I do not claim any new key-board nor any new alphabet or signals; I do
not claim any new register or recording instrument; but what I claim as my
invention or discovery, and desire to secure by Letters Patent, is -
The utilization of natural electricity from elevated points by
connecting the opposite polarity of the celestial and terrestrial bodies
of electricity at different points by suitable conductors, and, for
telegraphic purposes, relying upon the disturbance produced in the two
electro-opposite bodies (or the earth and the atmosphere) by an
interruption of the continuity of one of the conductors from the
electrical body being indicated upon its opposite or corresponding
terminus, and thus producing a circuit or communication between the two
without an artificial battery or the further use of wires or cables to
connect the co-operating stations.
