- Cathode Tube. While working at Philco, Farnsworth
began to develop his "multipactor" tube which
had the ability to transmit television impulses and
could be used as well as an amplifier, detector,
rectifier, and multiplier tube. It was the first
"cold cathode" tube and it was hailed by scientists
and engineers as a major breakthrough.

Telephon-del-green
Monument. Since
his death, various individuals and groups in
Murray, Kentucky have publicized Murray as the
Birthplace of Radio, a claim which is not widely
recognized, and Stubblefield as the Father of
Broadcasting, a claim which has more merit. Loren
J. Hortin, Journalism Professor at Murray State,
organized his students to investigate
Stubblefield's work, leading to the dedication of a
monument on campus in 1930. Hortin later said,
"Radio is a device that transmits and receives
voice over considerable distance without connecting
wires. Stubblefield invented, manufactured, and
demonstrated such a device and did so before anyone
else on the planet." The radio station in Murray,
WNBS, used Stubblefield's initials in its call
letters. (Lochte)

Stubblefield Memorial Marker Dedication --Murray
State honored Nathan B. Stubblefield with the
erection of Headstone Monument. The dedication took
place in Murray,
Kentucky,
on March 28, 1930,
where the Wireless Telephone was invented and
demonstrated, just across the street from the
Teléph-on-délgreen school house. Of
the Stubblefield family, only Helen,, Victoria and
Oliver, (Troy's father), were on hand at the
unveiling. Bernard, Nathan Jr., Pattie and Ada,
were no shows. The marker reads, "Here in 1902,
Nathan B. Stubblefield, 1860 - 1928, inventor of
radio, broadcast and received the human voice by
wireless. He made experiments 10 years earlier. The
home was 100 feet west. "Rainey T. Wells headed the

1930s 0829 - LETTER - 1930: August 30, 1930,
from Taylor & Taylor, Attorneys at Law, Little
Rock, Arkansas.
•••
Dear Mr. Stubblefield:
•••
I had a letter some time ago from Mr. Walter C.
Sheppard in which he stated that you were having
correspondence with your mother, Mrs. Nathan B.
Stubblefield, and your sister, Mrs. J. H. White,
but they informed me that they have not heard from
you. It is their presumption and mine that you are
working on the experiments in accordance with your
plan as outlined to Mr. Sheppard. I suggest that
you communicate with your family in order that they
may know what to expect.
•••
Mr. Sheppard as well as myself are waiting the
outcome of your experiments to accept employment in
this matter, but if anything at all is to be done
it must be done right away, as the time as you
already know is growing short. In other words,
there can be no recovery at all after May 12th of
next year.
•••
Trusting we may hear from you at an early date, I
am, Very truly yours, Beloit Taylor.

1930s 0105 - LETTER - 1930: REG. MISSING
PATENT, January 5, 1930, From Bernard St. to Ada M.
Stubblefield, Little Rock, Ark., (handwritten
original)&emdash; Your letter of Dec. 30/29 recd. I
made a search of the papers you spoke of, but
couldn't find any of the Wireless Telephone
Patents. I am enclosing some copies, filing
receipts and a photostat copy of the patent as
appeared in the Patent Office Gazette. These copy
in question may still be in some picture frame with
some of Father's effects, still at Uncle Walters.
You all write ask him to take another look, and to
also look for a diary this is also missing ask Vick
if He sent it to her as there is a copy of an
important paper in it for her, under date of May
14, 1917. (Referring to 1908 Patent) A photostat
copy of a note to that effect is herein
enclosed.
•••
The fact that the Patent is missing would not in my
opinion effect any of our rights in case those were
infringements during the life of the Patent or
Patents as the case may be. All of the Patents are
out of date, that is not in force. Even if those
were infringements during the life of the Patents
it would be a production proposition, and cost a
mint of money to prosecute the matter, even then we
would get only a little more than (illegible) as
there is a lot of others that held a share in the
Invention. B. B. Stubblefield.

1934 - FCC Function: to control and regulate radio
frequencies and spectrums. The radio spectrum is
the radio frequency (RF) portion of the
electromagnetic spectrum. In the United States,
regulatory responsibility for the radio spectrum is
divided between the Federal Communications
Commission (FCC) and the National
Telecommunications and Information Administration
(NTIA). The FCC, which is an independent regulatory
agency, administers spectrum for non-Federal use
(i.e., state, local government, commercial, private
internal business, and personal use) and the NTIA,
which is an operating unit of the Department of
Commerce, administers spectrum for Federal use
(e.g., use by the Army, the FAA, and the FBI).
Within the FCC, the Office of Engineering and
Technology (OET) provides advice on technical and
policy issues pertaining to spectrum allocation and
use.

Communications Policy Legislation. *(See Footnote.)
This legislative act remains the cornerstone of

initial passage. Though often updated through
amendments, and itself based on the pioneering
Radio Act of 1927, the 1934 legislation which
created the Federal Communications Commission has
endured remarkably well through an era of dramatic
technical and social change; By 1934 pressure to
consolidate all telecommunication regulation for
both wired and wireless services prompted new

pressure to deregulate all telecommunication
regulation for both wired and wireless services for

sell his patents outright in 1938.

- 1944 - Kentucky Dam. TVA (Tennessee Valley
Authority) - Located in Western Kentucky on the
Tennessee River creates the largest manmade lake in
the Eastern
U.S.
The huge job of
building Kentucky Dam took six years from the start
of construction on July 1, 1938, until the
reservoir began filling on August 30, 1944. More
important than the project's size are the jobs it
performs. Kentucky Dam is the spigot that TVA
(Tennessee Valley Authority) uses to help control
floods on the lower Ohio and Mississippi rivers; it
is the gateway to the Tennessee River waterway and
is a major generating plant in the TVA power
system.

1939f
- Farnsworth and
RCA. In 1939, RCA
obtained a license from Farnsworth to produce
electronic television transmission systems that
combined his technology with theirs. Farnsworth
later conducted research on radar and nuclear
energy. Zworykin And Sarnoff went to California a
couple of months later -- to see what Philo was up
to in his laboratory. Later Zworykin was said to
have claimed that RCA wouldn't need anything
Farnsworth had done. Then RCA's tough chief, David
Sarnoff, came to take a look. He echoed Zworykin.
But later RCA found that it very badly needed some
of Farnsworth's patents and paid for rights on a
royalty arrangement.
•••
••• The young American and the
Russian emigre worked contemporaneously, though
separately, to develop television. When Farnsworth
applied for an electronic television patent he
really shook RCA, whose laboratories under Vladimir
Zworykin had long been struggling with the problem.
RCA challenged the application.
