Dr. James Harris Rogers (1850 — 1029)
Dr f James Harris Rogers was born in Franklyn, Tenn-
essee, July 13tn, 1850, tne son of a. James Webb Rogers
and Cornelia (Harris )Hogers. lie was educated under pri-
vate tutors and at st. UHarles uollege in London, England,
and later received nonorary degrees of Doctor of .science
at Georgetown University and tne University of Maryland.
nis entire life was devoted to scientific work, special-
izing in electrical research. He was awarded about fifty
patents by tne United States and other governments relat-
ing to multiplex and rapiu printing telegraphy, electric
lights and radio telegraphy. tie was the discoverer of vis-
ual synchrony ism used extensively today in television,
and tne collector of considerable scientific data in con-
nection with underground and underwater radio communica-
Dr. Rogers was an Honorary Fellow of the Maryland
Academy of aciences (1919) and the holder of its inventor* s
medal. The General Assembly of Maryland, by joint reso-
lution of the House and aenate, extended him a vote of
thanks for his great contribution to scienc and service
to his uountry during the World War.
Dr. Rogers resided in Hyattsville, Prince George's
county, Maryland, from 1895 to Dec. 12, 1989 when he died
from a neart attack at his home. He was unmarried and a
member of tne ^atnolic Unurch.
AN INTERVIEW w]TH DOCTOR JAMES HARRIS ROGERS
An audience with Dr. James Harris Rogers, the Hyatt s-
ville inventor who has made Mrryland unique in the radio
world, is the unfulfilled desire of radio students and
enthusiasts throughout the United States. Years ago
while everybody was reaching into the air to pull down
signals, Dr. Rogers was investigating the possibility of
tapping the waves of energy that travel beneath the earth's
surface. The success of these subterranean experiments
is a matter of common knowledge.
It has been the writer's privilege to talk with
this distinguished gentleman. Dr. Rogers makes his home
at Firwood with his brother Joseph Rogers. The home place
is a large wooden structure
set in spacious grounds, of
the type characteristic of
the South before the Civil
War. At the outset, it is
unfortunate to have to re-
late that the experimental

greatly impeded in recent years on account of failing
health. Dr. Rogers is now approaching his eightieth
Soon after our exchange of greetings, '"The Doctor,"
as he is known to his home folks, was thumbing the pages
of an old scrap book and explaining to me his life's
work. It contained newspaper clippings from all over
the world elaborating on his inventions. Presently a
smile came over his face and h© said, "Here is an ac-
count of one of my earliest electrical adventures."
It explained how at the age of 15 years, Dr. Rogers em-
ployed a black cat as a telegraph relay. A boot was
adopted as the container for the animal, holes being
cut in the toe from where the hind feet of the cat pro-
truded and the front feet being tied with the, lacee. A
telegraph key in the secondary circuit was connected to
one paw. The high tension primary circuit was then passed
through the cat and its muscular reaction responded to
the -lots and dashes of the ^orse system. Dr. Rogers said
it was one cat that never came back* The idea, however,
was original and its success encouraged him to experiment
further and ascertain means where it would not be necessary
to employ a oat as a piece of electrical apparatus.
Passing on through the scrap book, it was learned
that Dr. Rogers at the age of 27 yenrs was appointed.
Chief Electrician at the Capitol at Washington. While
there he made many experiments with the electric light,
and installed according to his own design a device
called the Thermotele Meter by which' the temperature
in any part of the Capitol could he read in the toiler
Perhaps his first great invention was the print-
ing telegraph. By this apparatus, anyone who understood
the operation of a typewriter could send a message, with
this machine as many as 200 words a minute could he sent
as compared with 20 words transmitted by the old Morse
key system. For more complete details of this device,
the writer refers you to an article by "5. Ellesmere
McEeige, entitled "The Electrical Inventions of Dr.
James Harris Rogers" in the library of Phi Mu Fratern-
ity at the University of
Maryland. Howesrer, it may

Continuing on through the hook, Dr. Rogers came
to his work on underground transmission and reception.
Immediately his eyes brightened, for it was this work
in which he was most interested, notwithstanding his
experiments along these lines are left uncompleted on
account of failing health. Dr. Rogers was a pioneer
in this field of radio endeavor, and the results he
obtained elevated him to much the same distinction en-
joyed by men like Hertz, Edison, Marconi and Bell.
Dr. Rogers* invention making radio practical for sub-
marines is considered one of the great War ti^e dis-
coveries. His genius was employed to save life and
not to destroy life.
As early as 1908, Dr. Rogers conceived the idea
that the earth, and not the air, is the medium through
which most radio waves are propogated. As a conse-
quence he conducted experiments proving that the earth
is a conductor of this energy. Although the messages
received were weak, the results were unmistakable, but
pressing duties prevented him from further developing
later on, with the beginning of the World War in
1917, Dr. Rogers devoted all of his time to this sub-
ject, for he readily understood that if his idea of
underground antenna were practical, it could be used
to great advantage in the trenches and dug-outs.
In 1918 Dr. Rogers' efforts were Drought to the
attention of the Nagy Department at Washington. He
had a hut constructed in the woods near Hyatt svi lie
where work could be carried on secretly. Antennae,
radiating in all directions like the spokes of a wheel,
were buried under the hut, and it was in this manner
that the practicability of his idea was positively es-
tablished. At the same time, Dr. Rogers conceived the
idea that similar means of communication might be ex-
tended to submarines while submerged,
■Ippreciating the value of these theories, the Navy
Department offered to send Dr. Rogers to Hew Orleans
where his experiment s could be carried on in a more ex-
tensive way. He was placed under a bond of secrecy,
thus promising not to make application for any kind of
patent pending. This he was only too glad to do. How-
ever, Dr. Rogers, because of his health, was unable to
go to Hew Orleans, but his assistant was sent with whom
he endeavored to keep in communication.
As matters developed, however, it appeared that the
Navy Department withheld certain results of these ex-
periments. Becoming disappointed with the lacteof coop-
Dr. Rogers at his Transmitter 3 X R.
eratlon on the part of these officials, Dr. Rogers
successfully tested his ovm ideas by means fey an im-
provised submarine. He at first
planned to trail a wire behind ,
the submarine, but found this
impractical because of the pro-
peller. He then decided to run
the wires out of the conning
tower and oonnect them electri-
cally with the ends of the hull,
thus forming a loop with the
submarine as one side. This
proved to be a practical prop-
Dr. Rogers Ipril, 1929
Ten days after the Navy Department released Dr.
Rogers from his agreement of secrecy, he applied for
letters patent on his submarine antenna. A patent was
granted him, but later on the Commissioner of Patents
recalled his patent in favor of two employees of the
Bureau of Standards of the United States Government.
The matter was appealed to the District Court of Ippeals
and the decision was reversed in favor of Dr. Rogers,
but on a later trial of the case in a Federal Court
at Baltimore, the patent rights again were taken from
the Hyattsville inventor.
This episode in Dr. Roger s f career is a tragic
one. Vfter having spent thousands of dollars to assert
a claim he considers just and right, he awakes today to
find himself too impoverished to proceed further. He
could have applied for letters patent during the early
days of the War, hut refrained because the information
might have been disseminated to the enemies of his
Country. Nonetheless, the delay cost him the credit
of his greatest achievement.
After my interview with Dr.
Rogers, I was accorded the oppor-
tunity to visit his laboratory,
which has fallen into disuse
after two yeprs vacancy. Coils,,
batteries, radio sets and vacuum
tubes were strewn everywhere.
The outer room was used as an
office. The next room served
as the work shop and pieces of
electrical apparatus of every
description were in evidence
everywhere. In larp:e glass
cases surrounding the room were models of his inven-
tions, such as the printing telegraph, loop antenna, etc

In another room, adjoining the work shop, was
the famous radio broadcasting station "5 X R" , which
Dr. Rogers equipped himself and sent messages that
were heard from the Atlantic- to the Pacific and in
France, England and Germany. Dr. Rogers was able to
receive messages as well as send them and during the
World War listened regularly to the official reports
broadcast to the German submarines by the Home Office.
The underground aerial is used exclusively at Station

Hyattsville, Md., Dec. 12— Dr.
James Harris Rogers, inventor and
pioneer in underground and under-
water radio communication, died sud-
denly early today at his home, Ifir-
iyi-'.-'iI, from a heart attack.
The scientist, who was TO years old,
was apparently in good health* last
night when he entertained members of
his family. He became ill after he re-
tired and died shortly after Dr.
Thomas K. Latimer arrived.
Experimented During War
During the World War Dr. Rogers
constructed a dugout near his home,
where he demonstrated the value of un-
derground radio. In a small lake near
by he made experiments In underwater
communication, later demonstrating his
discoveries in salt water at Piney Point,
Dr. Rogers offered (he results of his
research and experiments to the Gov-
ernment at the outbreak of the war.
During the conflict the United States
was able to carry on uninterrupted com-
munication with the Allied govern-
ments, with submarines when sub-
merged and with battleships and air-
planes by means of principals devel-
Father Was In Confederate Army
Dr. Latimer said that the long hours
that Dr. Rogers worked in the dugout
during 1017 brought on carbon mon-
oxide poisoning which left the inven-
tor in a weakened condition.
Dr. Rogers was a son of James
Webb and Cornelia R. Rogers, and
was born in Pranklyn, Tenn. His
father served in the Confederate Army
and later settled near Bladensburg,
where the Rogers home, the Parthe-
non, is one of the historic spots. Dr.
Rogers lived at the family home until
about thirty years ago, when he moved
to Firwood. He never married.
Studied In London College
The inventor was educated by pri-
vate tutors and at St. Charles College,
