On Nov. 9, 1911, the U.S. patent
office received a
document which read: “Be it known that
I, Georges Claude, a citizen of the republic of France, have invented a certain
new and useful improvement in systems of illuminating by luminescent tubes, of
which the following is a specification.” In
the 17th Century, many scientists experimented with atmospheric air, including
Italian physicist Evangelista Torricelli, who, in 1644, constructed the first
recorded mercury column barometer in which he observed that, when shaken, it
would emit a bluish light in the dark. When
such scientists as Henry Cavendish and Benjamin Franklin investigated
“electrified atmospheres,” they discovered that the resulting light’s color is
also dependent on the chemical composition of gas and pressure. They didn’t have much success “diluting” the
gases because the vacuum technique was very primitive. Scientists’ primary problem (keeping
gases under low pressure pure inside the tube) was solved in 1858 by German
glassblower Heinrich Geissler, who discovered platinum wire inserted through
Thuringian glass creates a perfect vacuum-tight seal. In 1895, German engineer Carl von Linde found
a way to liquify air and, in 1902, he discovered how to separate its main
compounds (oxygen and nitrogen) by low-temperature distillation. During the air separation process, such inert
gases as argon, neon, krypton and xenon were leftover as surplus waste products. Linde’s concurrent, Frenchman Georges Claude,
was seeking a commercial use for such “waste” gases. In addition to his knowledge about the Moore
tube, Claude knew that a chemical reaction between the gas and electrode
material caused a drop in gas pressure.
Thus, by experimenting with different gasses and electrode materials, he
discovered that the gas should be chemically inert, and that the electrical
load for a given electrode surface must remain below a level of 4.5mA/cm2 (29mA
per sq. in.). Claude also found neon to
have the best light output vs. electrical-resistance ratio. Consequently, the neon-lighting tube was
developed and became patented on Jan. 19th, 1915, as U.S. Patent 1,125,476. Claude
fully exploited his patent commercially.
He alone made and sold the signs in Paris and quickly spread out to
other big cities. In 1922, Claude sold
the first two identical signs to the Los Angeles-based Packard dealership of
Earle C. Anthony for $1,250 apiece. The demand
for neon signs increased to such an extent that Claude couldn’t fulfill all the
requests he received. Thus, he finally
decided to sell franchise licenses outside of France for $100,000, plus
royalties for each one. The popularity
of neon continued to rise, and “Claude Neon” became so popular that many
thought Neon was the last name of the inventor. Because so many people wanted a piece of this
breakthrough technology’s success, fierce commercial strife began to emerge. In the patent war that took place from the
1920s up to 1932, the courts declared numerous claims made by the Claude
organization invalid, but the fundamental claim on electrode size was declared
valid. In the
early 1980s, an energy crisis lead to a push in low-consumption lightsources,
triggering new research on new luminous materials. Highly efficient fluorescent materials were
introduced to the neon world from the lighting business, and the range of
available colors increased to nearly 100.

The Young Electric Sign Company (YESCO) was created by Thomas Young on March 20,
1920. The
young sign painter had left England just a decade earlier to immigrate
with his family to Ogden, Utah. In the
beginning, his shop specialized in coffin plates, gold leaf window lettering,
lighted signs and painted advertisements.
As the science of lighting and sign-making advanced, so did Tom Young’s
signs. In 1933, YESCO opened a branch
office in the Apache
Hotel in
Las Vegas. The company erected the first
neon sign in Las Vegas for the Boulder
Club. YESCO soon became
recognized as a leader in the sign industry, tackling large and complex sign
projects. For example, it erected the
first neon spectacular sign in Las Vegas for the Boulder Club in the late ’30s,
and in 1995 it completed the four-block-long Fremont Street Experience canopy
in Las Vegas. http://en.wikipedia.org/wiki/Young_Electric_Sign_Company

Local author Paul Many has pledged $1,000 of advance book royalties to the
Early Literacy Campaign of the Toledo Lucas County Public Library if his sci-fi
novel SilverSky wins enough nominations to be accepted as a Kindle
e-book. If the book receives enough
nominations, and Amazon offers a Kindle contract, Many pledges to donate $1,000
of his $1,500 advance to the Literacy Campaign.
The book, inspired by
Edgar Rice Burroughs' pulp fiction titles such as "The Gods of Mars,"
has made the first cut in the new Kindle "Scout" program from
Amazon that seeks to crowd-source new books for electronic publication. To nominate the book with no cost or
obligation, search "SilverSky Kindle Scout" on Google, or go directly
to https://kindlescout.amazon.com/p/1P5LJG10GMOZE
Many, a retired
University of Toledo professor, is the author of three teen books and two
children's picture books with another forthcoming--all from major
publishers.
With nearly one-third of
Toledo-area children not prepared to enter kindergarten ready to read and
write, the Library Legacy Foundation initiated the Early Literacy Campaign to
bring essential early literacy skills and training to the areas of the Toledo
community that are most at-risk. A specially-equipped library van to
bring materials into target neighborhoods is already up and running, and the
program provides other features such as literacy kits for parents and daycare
teachers.
The New York Public Library’s vaunted Rose Main Reading Room has been closed since
a plaster rosette fell from its ceiling in May, so for the Library Lions gala November
3, 2014, the library transformed hallways and other rooms of the Stephen A.
Schwarzman building into a twinkling, Narnia-esque forest. Two of this year’s lions, the author Margaret
Atwood and Robert Silvers, editor of the New York Review of Books, stood
chatting, medallions hanging around their necks on thick red ribbons. Ms. Atwood and several other authors have
pledged to auction the name of a character in a coming story to raise money for
Freedom from Torture, which provides therapy and support to torture
survivors. The
other three honorees were the authors Dave Eggers and Kazuo Ishiguro, and the
actress and playwright Anna Deavere Smith.

A painting is a world without
change and without sound. Johannes Vermeer's paintings are
full of musical instruments and people making music. In almost one third of his paintings, music is
present in one way or another. The fact
that Vermeer portrayed so many musical themes is not surprising in itself,
"at least ten percent of all 17th-century paintings, music makes its
appearance in one way or another. In
genre pieces, in which category Vermeer's work is generally placed, the
percentage is even higher. For example,
about 20 per cent of Frans van Mieris' works, 25 per cent of Pieter de Hoogh's
and almost half of Jacob Ochtervelt's deal in some way with music." Link to more information, including articles

Vermeer" under the heading Dutch Music in Vermeer's Time.

November 7, 2014 On this date in 1929,
in New
York City, the Museum of Modern Art opened to the public. On this date in 1967, Lyndon
B. Johnson signed the Public Broadcasting Act of 1967,
establishing the Corporation for Public Broadcasting.
