1940s 1210 - LETTER - December 10, 1940, from
Bernard to Mr. Ira Prichard, 300 B. M. A. Bldg.,
Kansas City, Mo., (handwritten copy). . . You speak
of writing a Biography. You do not state in what
form, a book, magazine or merely a news article.
There has already been so much in news articles
that it is rather stale. To publish a book would
require a lot of technical matter. This would have
to come from one skilled in the art of today, or
well or the stages of its early development. It
would require numerous photographs or well a
diagram of an explanatory nature all technical, so
as to make clear the various types of equipment
used.
Such book would have a commercial value. After all,
a biography is rightly a part of our estate. Would
like to hear from you further or to your proposal.
Very sincerely, B. B. Stubblefield.

1940s1001 - THE COURIER-JOURNAL - October 1940.
WILL A LAKE BEND THE EARTH? Kentucky Dam will form
a 2-billion body of water and scientist grow
curious, By R. M. Woodall. Group which will observe
the effect of this weight is the Nathan B.
Stubblefield Physics Club of Murray State College.
The college is only a few miles from where the left
bank of the lake will be and about twenty-five
miles from Gilbertsville, Ky., site of the dam. The
club, named after the inventor of radio, who lived
in Murray, has erected a Foucault pendulum to
measure the effect, if any, of the water's weight
on the earth's crust.
1940 - President Franklin Roosevelt names Nelson
Coordinator of Inter-American Affairs, to stem Nazi
influence in Latin America.
1941
- FCC authorizes FM broadcasting on 42-50

1941f - Pearl Harbor and Radar Equipment. But the
price, due to high development costs, was over a
million dollars and they were unsuccessful. The
syndicate then decided to go it alone and bought
the Capehart Corporation in Fort Wayne, Indiana, to
manufacture television sets. But Pearl Harbor ended
any such possibilities and Farnsworth's company
built radar equipment instead.
1942 - The manufacture of radio sets was stopped
due to the war, and manufacturers switch to defense
activities. British mathematician and science
fiction writer Arthur C. Clark suggests using
satellites to relay radio signals about 20 years
before the first satellite, Sputnik I was placed in
orbit!
1942f - For years Farnsworth and his partners had
refused to get involved with the manufacturing of
television sets, yet they finally broke this
barrier when they bought the Capehart Company of
Fort Wayne, Indiana. Up to that time Capehart had
been known best for its large coin music boxes
installed in bars, dance halls, and
restaurants.
1943 - Great strides are made in technology and
manufacturing as radio is used in the war.
Meanwhile at home, many receivers are remodeled
with whatever parts are on hand - as wartime
shortages and aging radio sets combine for some
creative electronics repair.
1943
0107 - Died: Nikola Tesla (1856-1943), on January
7, in New York City. (AC Hi-Frequency Generator;
Remote Radio Signal).
He died of heart
failure alone in a hotel room at age 87. Despite
selling his AC electricity patents, Tesla was
essentially destitute and died with significant
debts.
1943t - Immediately after Tesla's death became
known, the Federal Bureau of Investigation
instructed the Office of Alien Property to take
possession of his papers and property, despite his
US citizenship. His safe at the hotel was also
opened. At the time of his death, Tesla had been
continuing work on the teleforce weapon, or death
ray, that he had unsuccessfully marketed to the US
War Department. It appears that his proposed death
ray was related to his research into ball lightning
and plasma and was composed of a particle beam
weapon. The U.S. Government did not find a
prototype of the device in the safe. After the FBI
was contacted by the War Department, his papers
were declared to be top secret. The so-called
"peace ray" constitutes a part of some conspiracy
theories as a means of destruction. The personal
effects were seized on the advice of presidential
advisors, and J. Edgar Hoover declared the case
"most secret", because of the nature of Tesla's
inventions and patents. One document states that
"[he] is reported to have some 80 trunks in
different places containing transcripts and plans
having to do with his experiments.
1943t - Tesla's family and the Yugoslav embassy
struggled with the American authorities to gain
these items after his death due to the potential
significance of some of his research. Eventually,
his nephew, Sava Kosanovic, got possession of some
of his personal effects which are now housed in the
Nikola Tesla Museum in Belgrade, Serbia.
1943t - Tesla's funeral took place on January 12,
1943, at the Cathedral of Saint John the Divine in
Manhattan, New York City. After the funeral, his
body was cremated.
1943t-
The US Supreme Court upheld Tesla's patent number
645,576 in effect recognizing him as the inventor
of radio.

- U.S. Court holds Marconi patent claims
invalid.
On June 21, 1943
the Supreme Court of the United States held the
broad claims of Guglielmo Marconi's patent for
improvements in apparatus for wireless telegraphy
to be invalid. First written for publication by the
Antique Wireless Association, this monograph shows
how the nation's high court arrived at its
decision. It provides an answer to the continuing
argument regarding the popular misconception that
Marconi invented radio.

- Black Marketing of Automobiles. During the war
years Calloway County became the focal point of a
national scandal publicized in "Life,"
magazine,
featuring the black marketing of automobiles. Sales
rooms included the garage building on Main Street
just west of the intersection of North 5th Street
where "Life" photographers peepholed photos of the
operation. The new booming business outgrew the
Main Street quarters and moved to a huge tobacco
warehouse on Maple Street. After the publicized
article appeared nation-wide, federal agents moved
in, secured approximately 20 convictions which
resulted in prison terms for many of some of
Murray's most influential business men. Not only
was the art of black marketing cars limited to
highway vehicles, for the trafficking also embraced
farm vehicles. -"The Story of Calloway County,"
Published by Kerby and Dorothy Jennings.
1945 - Harry S. Truman: Thirty-Third U.S.

been the plan all along by those involved with AM
broadcasting.

1945
- United Nation (UN). It was founded in 1945 at the
signing of the United Nations Charter by 51
countries, replacing the League of Nations founded
in 1919.
The UN is an
international organization whose stated aims are to
facilitate co-operation in international law,
international security, economic development, and
social equity.The UN was founded after the end of
World War II by the victorious allied powers with
the hope that it would act to prevent and intervene
in conflicts between nations and make future wars
impossible or limited. Headquarters:
Manhattan Island, New York City,
NY.
1946 - After the war, the Rockefeller brothers of
the third generation (John D. III, Nelson,
Laurance, Winthrop, and David) return to the family
office at Rockefeller Center, eager to define their
individual roles. The Rockefellers offer the United
Nations a tract of land on their Pocantico estate
as a site for its headquarters. When that plan
falls through, Nelson persuades John D. Rockefeller
Jr. to purchase land on New York City's East River
and donate it to the United Nations.
1946 - AT&T Bell Telephone Laboratories
scientists John Bardeen, Walter Brattain, and
William Shockley invent the transistor, the first
solid state amplifier or switch, and lay the
foundation for modern electronics. The three shared
the Nobel Prize in Physics in 1956 for the
achievement.
1946 - AT&T
develops the concept of cellular telephony.
1946
- The basic concept of cellular phones began in
1946, when
researchers looked at crude mobile (car) phones and
realized that by using small cells (range of
service area) with frequency reuse they could
increase the traffic capacity of mobile phones
substantially. However at that time, the technology
to do so was nonexistent.
1946
- AT&T begins offering mobile telephone
service.
With a single antenna
serving a region, no more than 12 to 20
simultaneous calls could be made in an entire
metropolitan area.
1946
- Rainey T. Wells retired as general attorney for
Woodmen of the World, Omaha, Nebr. He returned to
Murray to make his permanent home in
retirement.
1946d - Lee De Forest grows increasingly unhappy
with the state of broadcasting. To him, radio had
become 'a stench in the nostril of the gods of the
ionosphere.' He addresses the National Association
of Broadcasters at their annual meeting in Chicago.
Table model radios are the big seller. Over 15
million sets are produced. About half a million of
those were FM receivers. Selenium rectifiers begin
to replace vacuum tube rectifiers.
1947 - A Modern Approach - In 1947, after the
Second World War, ITU held a conference in Atlantic
City with the aim of developing and modernizing the
organization. Under an agreement with the newly
created United Nations, it became a UN specialized
agency on 15 October 1947, and the headquarters of
the organization were transferred in 1948 from Bern
to Geneva. At the same time, the International
Frequency Registration Board (IFRB) was established
to coordinate the increasingly complicated task of
managing the radio-frequency spectrum; the same
year, the Table of Frequency Allocations,
introduced in 1912, was declared mandatory.
1947 - Radios are shrinking in size, and over 800
thousand FM receivers are produced. Miniature
tubes, rectifiers, transformers, and printed
circuit boards are used. John Bardeen, Walter
Brattain, and William Shokley invent the
Transistor.
1947do - The Amos Emerson Dolbear Scholarships
established, by the bequest of Katherine E. Dolbear
(class of 1897) in memory of her father, the
eminent scientist and inventor, who was professor
of physics at Tufts from 1874 to 1910. The Dolbear
scholarships are awarded to seniors who have shown
promise in the field of either physics or
electrical engineering. Dolbear contributed many
notable inventions to the scientific world,
including the static telephone, the electric
gyroscope used to demonstrate the Earth's rotation,
the opeidoscope, and a new system of incandescent
lighting.
1948 - Alexanderson was awarded an honorary
doctorate by the Royal Institute of Technology,
Stockholm.
1948 - AT&T begins offering networking services
for television on facilities connecting major
cities in the northeast and Midwest. The service
reaches the west coast in 1951. Television networks
use this service to transmit programming to their
affiliated stations around the country.
1948
- Citizen's Band (CB) Radio. Al Gross convinces the
FCC and its head engineers in 1948 to provide for a
license-free part of spectrum that would support
personal
communications.
This later became known as Citizen's Band (CB)
radio. - comsoc.org.
1948
- The FCC announces a three month freeze on new TV
station applications.
It lasts nearly
four years! TV picks up steam. 10 inch screens are
the most common. The LP or Long Play phonograph was
introduced. The first Transistor is introduced to
the public.
1948al - Alexanderson formally retired from General
Electric but continued his inventing activities as
a private person for a further 20 or so years.
During that time he obtained 28 patents in a
variety of fields. His last patent he acquired as
recently as 1973.
1948s
- Radio Station WNBS whose call letters symbolize
the initials of Nathan B. Stubblefield, went on the
air
the week of June 29,
1948. Radio had had a unique history in Calloway
County, beginning with the transmission of the
human voice by Nathan B. Stubblefield at the
beginning of the century. -"The Story of Calloway
County," Published by Kerby and Dorothy
Jennings.
1949
1004 - The Calloway County Fiscal Court has
appropriated $1,000 for a monument to Nathan B.
Stubblefield to be built on the NW corner of the
Court
square.
Judge Pink Curd
said that tentative plans call for the United
Daughters of the Confederacy of the county to erect
a marker and an iron fence around the N. B.
Stubblefield grave.
