I stopped by Book Baron (www.bookbaron.com) yesterday and picked up a
$7 used paperback of The Last Lone Inventor (http://www.lastlone.com).
I've been reading a few chapters of the story of Television, Philo T.
Farnsworth and David Sarnoff, which everyone should read. Right now
you are probably watching a CRT which was invented by Farnsworth.
It's truly amazing. Little did he know how much his invention would
change the world.

Cool. But didn't Ferdinand Braun invent the CRT? About 1896 or '7.

Another good book: Tube, by Fisher & Fisher.

It's true. The basics of the CRT were known by the turn of the twentieth
century.

Farnsworth's contribution was the first working all-electronic camera,
though his invention had drawbacks that limited its commercial success.

And little does anyone know that RCA, which was David Sarnoff's company at that
time, pretty much stole the idea from Philo Farnsworth. Mr. Farnsworth never
really profited from his invention.

Well, at least there's consolation for the Farnsworth family: RCA is a failed
corporation which lost its sovereignty in 1986 when it was acquired by General
Electric. Now, RCA is owned by Thomson Electronics, which is controlled by the
French Government. - Reinhart

Yeah, they mentioned Braun in the first chap. But Farnsworth came up
with the idea of chopping the pic up and sending the lines
sequentially, and sweeping the beam across the screen, like the way
your CRT displays the video.

And then you come up against Sarnoff's version.

I don't think it would last long vented like that- it has to be sealed
in a vacuum- and that's how Electrolux got started.

I thought it was the Russian born Vladimir Kosma Zworykin who developed
the first working camera and picture tube at Westinghouse or was it RCA?

As compared to what, in Braun's version? Vector scanning?

As compared to NOTHING. The original CRT's had a gun and a target
face. It was flood illuminated. Virtually useless.

The "big leap forward" thing that Farnsworth did was to visualize
scanning lines.

So it was a lamp, and made no images at all?

Highlights of CRT History

1855 - German, Heinrich Geissler invents the Geissler tube, created
using his mercury pump this was the first good evacuated (of air)
vacuum tube later modified by Sir William Crookes.

1859 - German mathematician and physicist, Julius Plucker experiments
with invisible cathode rays. Cathode rays were first identified by
Julius Plucker.

1878 - Englishmen, Sir William Crookes was the first person to confirm
the existence of cathode rays by displaying them, with his invention
of the Crookes tube, a crude prototype for all future cathode ray
tubes.

1897 - German, Karl Ferdinand Braun invents the CRT oscilloscope - the
Braun Tube was the forerunner of today's television and radar tubes.

1929 - Vladimir Kosma Zworykin invented a cathode ray tube called the
kinescope - for use with a primitive television system.

1931 - Allen B. Du Mont made the first commercially practical and
durable CRT for television.
--------------------------------------------------------------------------------

In some parts of the world, CRTs are still called "Braun tubes". BTW,
mechanically scanned TVs were around too... pre-WWII, IIRC.

face. It was flood illuminated. Virtually useless.

See the reference I gave- electromagnetic deflection + mechanical
scanning, and later electrostatic deflection (but still well before
Farnsworth). The oscilloscope came long before the televison, and even
the "televisor".

I've seen those demo tubes with a Maltese cross in them that throw a
CR shadow on the end of the tube, but it seem Braun had better uses in
mind.
The "big leap forward" thing that Farnsworth did was to visualize
scanning lines.

Did this precede mechanically scanned TVs? It's not much of a leap to
go from a disk with holes in it to deflecting a beam to follow just
about the same path as the hole..

My mistake, I thought an inventor was someone who invents things and figured
Tony Blair did a lot of that.

There were several Farnsworth books timed to come out in 2001/2002.
"The Last Lone Inventor" is not the most accurate of them, just the
most-publicized. Find a copy of Daniel Stashower's "The Boy Genius
and the Mogul" for a more balanced account. There is also Donald G.
Godfrey's "Philo T. Farnsworth--the Father of Television" (which I
have not read).
