Who Invented Television?
Zworykin's
1938 Iconoscope patent, with the 1923 application date
"I know that God exists. I know that I have
never invented anything. I have been a medium by
which these things were given to the culture as
fast as the culture could earn them. I give all
the credit to God."
--Philo T. Farnsworth
As compelling as the story
of Philo T. Farnsworth may be, the historical record
with regard to "who invented television" remains
fuzzy at best, deliberately distorted at worst. The
debate often comes down to a simple question: Does any
single individual deserve to be remembered as the sole
inventor of television? Can we create for television
the kind of mythology of individual, creative genius
that history has bestowed on Morse, Edison, Bell, or
the Wright Brothers?
The question may be simple,
but clearly the answer is not. Before Uncle Milty, before
Walter Cronkite, before Lucy and Desi and Ethel and
Fred, literally hundreds of scientists and engineers
contributed to the development of the appliance that
now dominates "our living room dreams." How
can we single out any single individual and say, "it
all started here"?
The historical record
is sadly devoid of references to Farnsworth. Though
the oversight has begun to improve in recent years,
it is still entirely possible to open an encyclopedia
and read that electronic television began when "Vladimir
Zworykin invented the Iconoscope for RCA in 1923 ..."-a
sentence that manages to express no less than three
historical inaccuracies. The most conspicuous error-the
"1923" date-fixes Zworykin's name chronologically
before Farnsworth's 1927 patent filing, and often renders
Farnsworth to the status of "another contributor"
in the field.
Some historians have gone so far as to suggest that
Farnsworth and Zworykin should be regarded
as "co-inventors." But that conclusion ignores
Zworykin's 1930 visit to Farnsworth's lab, where many
witnesses heard Zworykin say "I wish that I might
have invented it." Moreover, it ignores the conclusion
of the patent office, in its 1935 decision in Interference
#64,027, which states quite clearly "priority of
invention awarded to Farnsworth."
These misinterpretations
of the historical record are precisely what more than
sixty years of corporate public relations wants us to
believe-that television was "too complex to be
invented by a single individual." But close examination
of the stories beneath the written record reveals a
far more compelling story: In fact, there was one inventor
of electronic television. Video as we now know it first
took root in the mind of Philo T. Farnsworth when he
was fourteen years old, and he was the first to successfully
demonstrate the principle, in his lab in San Francisco
on September 7, 1927. If you need to fix a date on which
television was invented, that's the date.
Before that date, television
was the province of Newtonian electro-mechanical engineers
who employed spinning disks and mirrors in their crude
attempts to scan, transmit, and reassemble a moving
image. The inventions of Jenkins, Ives, Alexanderson,
Baird, and others are all similar in their reliance
on the spiral-perforated, spinning disk first proposed
in the 1880s by the German Paul Nipkow. These contraptions
were engineering marvels in their own quaint way, but
they were not the sort of breakthrough that Farnsworth
introduced, nor is anything left of their technology
in the system of television that is in use around the
world today.
On September 7, 1927,
Philo T. Farnsworth demonstrated for the first time
that it was possible to transmit an "electrical
image" without the use of any mechanical contrivances
whatsoever. In one of the first triumphs of Relativistic
science, Farnsworth replaced the spinning disks and
mirrors with the electron itself, an object so small
and light that it could be deflected back and forth
within a vacuum tube tens of thousands of times per
second. Farnsworth was the first to form and manipulate
an electron beam, and that accomplishment represents
a quantum leap in human knowledge that is still in use
today.
After September 7, 1927,
every new contribution to the art-including Zworykin's-was
an improvement on Farnsworth's simple, elegant, and
profound invention
.
What is so often overlooked
cannot be overstated: In 1923, Vladimir Zworykin-recently
emigrated from Russia, and employed at the time by the
Westinghouse Corporation in Pittsburgh, Pennsylvania-applied
for a patent for an approach to television that he first
encountered in the classroom of Boris Rosing, his former
teacher in Russia. In 1927, Farnsworth also applied
for a patent. Later that year, Farnsworth produced the
first successful transmission of a television image
by wholly electronic means-an event that is thoroughly
documented in Farnsworth's journals-while Zworykin's
application was still pending.
Farnsworth's patent #1,773,980-with
the critical Claim 15 regarding the "electrical
image"-was issued in August 1930-and Zworykin's
application was still pending.
The 1923 Zworykin application
would be forgotten-except that a patent for the Iconoscope
was finally issued in 1938 bearing a 1923 application
date. This patent (#2,141,059) was issued an extraordinary
fifteen years after the application date, and then only
after extensive revisions had been made to the original
application.
Furthermore, the eventual
patent granted pursuant to the 1923 application was
issued over the objection of the patent office, and
even then not until the case was adjudicated by a court
of appeals. That the Iconoscope patent was issued at
all hinged on a technicality, and it served no practical
purpose other than substantiating the dates that RCA
would eventually use in its public relations campaign.
RCA's obtaining the patent
in 1938 has served as the cornerstone of its efforts
to influence the historical record, since the patent
effectively fixes 1923 as the date that Zworykin first
disclosed electronic television. Decades later, historians
and scholars are still including this dubious 1923 date
in their chronologies.
What's wrong with the
Zworykin patent? What's wrong with it is that the original
application-the system that Zworykin disclosed in 1923-simply
could not work. The idea was on the right track, but
the application fell far short of disclosing a device
that would pave the way to electronic video and ultimately
put a television in every living room or a computer
monitor on every desktop.
There is scant evidence
that Zworykin ever built and tested a system like the
one disclosed in his 1923 application. One story does
exist about Zworykin's attempt to demonstrate his concept
for executives of Westinghouse, where he was employed
at the time, in hopes of obtaining more funding for
his research. The demonstration was so dismal that instead
of providing him with further funding, Zworykin's superiors
ordered him to find something "more useful"
to work on.
The usual retelling of
this story is cast in such a way that we are supposed
to believe that the Westinghouse executives who witnessed
and dismissed this demonstration were too shortsighted
to appreciate its promise. It seems more plausible to
conclude that what they saw showed little promise because
it simply didn't work. Some historians suggest that
witnesses observed some sort of blurry smudge. Zworykin
would claim years later that the image of a cross was
transmitted. But during the critical 1934 interference
proceedings there was no evidence submitted to support
even these modest contentions.
It's hard to imagine anyone
in 1923 or 1924 seeing even an incoherent transmitted
image on the bottom of a bottle and telling its creator
to find something "more useful" to work on.
But that's what we're supposed to believe.
The most recent accounts
of Zworykin's debatable patent history are often traced
to The History of Television: 1884 - 1941 by Albert
Abramson. A careful examination of Abramson's book only
serves to further illustrate the flimsiness of this
account.
The actual evidence that such a demonstration ever took
place is sketchy at best, considering its potential
historical significance. There are no lab notes, no
direct eyewitness testimony. There are only Zworykin's
own accounts, and a single document on page 80 of Abramson's
book that he claims to have found buried in some archives
fifty years after the purported event. This document
describes a device "using a modified Braun type
cathode ray tube for transmitter and receiver ...the
receiving tube ...gave quite satisfactory results ...[but]
the transmitting part of the scheme caused more difficulties
...."
That's it; that's all
it says about the transmitter, that it "caused
more difficulties." It's hard to imagine how the
receiver could be "quite satisfactory" if
the transmitter was not equally satisfactory, but this
is the document that compels Abramson to conclude-in
his footnotes-that "Zworykin did build and operate
the first camera tubes in the world sometime between
the middle of 1924 and late 1925." This is the
feeble foundation on which historians build RCA's claim
that Zworykin should be regarded as the "inventor
of television."
Zworykin may indeed have
built some tubes. And he may have applied current to
them. But it should take more than a statement that
"the transmitter caused more difficulties"
to convince students of this history that he successfully
"operated" such a device prior to September
7, 1927, or that Zworykin even deserves to be considered
a "co-inventor" as a result of this experiment.
Historians should focus
more carefully on the decision of the U.S. Patent Office
in its historic 1935 ruling in Patent Interference Number
64,027. This is the litigation in which Zworykin challenged
Claim 15 in Farnsworth's patent #1,773,980, which describes
the "electrical image." An electrical image
is the electrical counterpart to an optical image. When
an optical image is focused on a photoelectric surface,
the light-sensitive chemicals emit an array of electrons-the
"electrical image"-which can then be scanned
to form a fluctuating current. That is the very essence
of how an electronic television signal is created, and
so it is understandable that Zworykin and RCA would
attempt to appropriate the language in this claim. There
is simply no getting around it-you can't create an electronic
television signal without first creating an "electrical
image."
The whole of RCA's research
effort-at an expense that David Sarnoff joked with Zworykin
years later cost RCA more than $50 million-was intended
to circumvent Farnsworth's patents, in particular Claim
15. When the electrical image in Claim 15 proved essential,
Sarnoff, Zworykin, and RCA's attorneys went to great
lengths in the 1934 interference to prove that the 1923
application would have created such an electrical image,
and that Zworykin was therefore entitled to "make
the count" embodied in Claim 15.
But when it was time for
RCA to produce material evidence that Zworykin had constructed
and operated his system in 1923, there was no evidence
submitted. No tubes were displayed, no laboratory journals
entered into the record. There were only confusing and
contradictory verbal accounts from two Zworykin colleagues.
After considering all the testimony, the patents examiners
ruled in Interference #64,027 that "Zworykin has
no right to make the count because it is not apparent
that the device would operate to produce a scanned electrical
image unless it has discrete globules capable of producing
discrete space charges and the Zworykin application
as filed does not disclose such a device."
The patent examiners were
unequivocal in their decision to award the indispensable
Claim 15 to Farnsworth. The case was appealed and RCA
lost all the appeals. This pattern went on, over this
and other patents, until RCA capitulated in 1939 and
accepted a license from Farnsworth for the use of his
patents-the first such license in the history of a company
that was determined to "collect patent royalties,
not pay them."
Yet, here we are nearly seventy years later, still debating
the merits of a patent that was awarded by a court of
appeals in 1938 that validated a patent applied for
in 1923 that was ruled inoperative in 1934.
The contradictions are
clear: What we have is an application for a patent in
1923, an unsuccessful demonstration in "1924 or
25" with no conclusive documentation, and a patent
interference ruling in 1934 that says the device was
inoperative. Nevertheless, a patent was obtained in
1938 which compels otherwise scholarly reporters to
conclude that Zworykin and Farnsworth must be considered
co-inventors.
A more discerning examination
of the record reveals that Zworykin believed in electronic
television but was still struggling for a viable solution
until he visited Farnsworth's lab in 1930. As soon as
he saw what Farnsworth had achieved, he got busy, duplicating
Farnsworth's equipment at the Westinghouse lab in Pittsburgh
before moving on to RCA in Camden. He then built on
Farnsworth's work, as well as the work of other contributors,
to produce the Iconoscope.
Zworykin's corporate benefactor,
David Sarnoff, believed the Iconoscope gave him the
leverage he needed to bring all the legal might of RCA
to bear on claiming Farnsworth's achievement as RCA's
own. Sarnoff ultimately failed in that effort, and RCA
was left with no choice but to accept a patent license
from Farnsworth. Still we read time and again that Zworykin
made modern television possible when he "invented
the Iconoscope for RCA in 1923." The facts are
that Zworykin was not working for RCA in 1923, the Iconoscope
did not exist at that time, and it is questionable whether
Zworykin truly invented it at all.
Zworykin got some momentum
going with the Iconoscope, but it was not until the
Image Orthicon tube was introduced that the industry
had the tool it really needed to bring the world into
our living rooms. But the Image Orthicon-originally
thought to be an RCA development-was in fact descended
from Farnsworth's patent #2,087,683, which was the first
to disclose a "low velocity" method of electron
scanning. This lends further credence to the notion
that everything that came after September 7, 1927 was
an improvement on the concept proven that day-including
Farnsworth's own subsequent inventions.
That said, there is no
question that much credit for refining all aspects of
television technology goes to RCA engineers. There were
hundreds, maybe thousands, of individuals who contributed
to the development of electronic video before television
broadcasting reached the general public in the 1950s,
and thousands more who have contributed to its advancement
in the decades since. But refinement is not invention,
though that is precisely what the proponents of the
"co-inventor" theory of the origins of television
would like us to accept.
Why is any of this important? Who really cares who invented television?
What difference does it make whether electronic television was first
developed by a Russian émigré or a Mormon farm boy? And
should it still matter seventy years after the fact?
It matters because the suppression of
the true story deprives us of some important knowledge of the human
character. It tempts us to believe that progress is the product of institutions,
not individuals. It tempts us to place our faith in those institutions,
rather than in ourselves.
Invention is one of the most unique and
compelling aspects of the human experience. From the moment the first
ape picked up a bone and swung it like a club, the history of civilization
has followed the path of invention.
Szent-Gyorgi put it best when he said,
"Discovery is seeing what everybody else has seen, and thinking
what nobody else has thought." Therein lies the operative definition
of genius. In Zworykin, we find a capable engineer, one who could see
what others were doing and improve upon it. But in Farnsworth, we encounter
the rarest breed of all, the true visionary who could see the obvious-and
think up something entirely different. Obscuring his story and denying
his contribution deprives us of our understanding of this critically
important facet of the human character.
Television is our blessing and our curse.
The ancient dream of a unified planet came true with the moonwalk in
1969, as hundreds of millions of people around the world tuned in to
witness the event through the medium of Philo T. Farnsworth's potato-field
inspiration. At the other extreme there are the routine daily programs
that cater to "the lowest common denominators" of our society.
But even these daily panderings to common culture are somehow elevated
when reconsidered with the knowledge that the medium itself is a consequence
of individual genius rather than corporate engineering.
The belief that television-the most pervasive
mass communications system of the past millennium, and perhaps the next-was
"too complex to be invented by a single individual" deprives
us of the knowledge of the noble individual whose unique intellect made
it all possible. There are only a few such souls in each century, men
like Tesla, Armstrong, and Einstein whose lives are an enduring expression
of Szent-Gyorgi's axiom.
Philo T. Farnsworth was as noble a spirit
as has ever graced this planet. From his earliest declaration of his
hope that he, too, had been "born an inventor" it is clear
that this earthly soul was an instrument of providence. When he saw
how the mad scientists of the 19th century tried to send pictures through
the air with spinning disks and mirrors, he alone replaced all the moving
parts with the invisible electron. Recalling that contribution makes
even the most ordinary moments of television programming an expression
of divine inspiration.
