Hi to all,

Hope this hasn't been indicated before.
if so, i am sorry.

Found this website with very interesting pdf data about German achievements in TV from the 1930s to the WWII years :

https://www.cdvandt.org/tv_tech_1940-42.htm

They are mostly periodical newsletter publications by Fernseh AG about the status of ongoing research. Texts are in German, but lots of photos, schematics & graphs. Tech is universal, if you make the effort, you can +/- easily grasp what's important.

For ACORNVALVE :
i'm a great admirer of your site !
This Newsletter has an article about the use of Flyback EHT in the E1 "People's TV receiver" which should have been built by the thousands but stopped dead by the war outbreak in Sept 1939 :

https://www.cdvandt.org/2bandheft3nov41.htm

More about the revolutionary E1 TV receiver with a true square 12" CRT & EHT Flyback in 1939.
Only 15 tubes + CRT, built-in radio :
https://www.cdvandt.org/tft_e1_h_7_1939.htm

And of course Eckhart Etzold's fabulous write up on the E1 TV (in English, photos) :
http://bs.cyty.com/menschen/e-etzold/ar ... ken/e1.htm

The entire German electronics database with loads of military radios, etc :
https://www.cdvandt.org/handbooks.htm

And this database (BIOS) of Allied Intelligence systematic analysis of German technology after the war had ended, all reports in English :
https://www.cdvandt.org/fiat-cios-bios.htm

If you only read one, this is it : "TV developments & Applications in Germany" :
https://www.cdvandt.org/bios-867.htm

Happy reading ! you can spend days there...

Best Regards

Now you have really thrown a Cat into the Pigeons.

Most collectors who are interested in vintage TV, especially of the pre-WW2 variety think that all the major research work was done in the USA or the UK. However, much of the important work was in fact done in Germany.

One of the movers and shakers was Manfred Von-Ardenne, a multi-talented Genius.

His book Television (in 1936) was so impressive, it inspired O.S. Puckle (from the Cossor company in the UK) to translate it into English. I have this book and have scanned a page (attached).

After reading this book, it was evident that Von Ardenne was well ahead of the curve. He had made very interesting CRT's which had both combined electrostatic and magnetic deflection. His work was thorough, mathematically analysed and supported by sound Physics. I would call it outstanding research.

When Von Ardenne passed away, I was quite saddened by this, and I kept a newspaper article that described his interesting life (attached).

Hi to all,
Hi Dr Holden,
Thanks ! for the reply.

I have a 1936 French book on television which shows +/- the same illustration as yours.

In Michaƫl Bennett-Levy's documentary "TV is King" there is rare footage of Manfred Von Ardenne which he interviewed a few years before MVA passed away.

https://youtu.be/UWTMenjrAwI

Bennett-Levy, a British antique dealer, developped a personal interest in Pre-War television.
There was a huge auction sale in England by Bonhams in 2009 for the dispersal of his collection.
I have the auction house's catalogue scanned somewhere in my files.

The Bonhams page :
https://www.bonhams.com/auctions/17616/
Pre-War TV items start page 56 & onwards. Can't memorize a direct link, Sorry !

try here nevertheless :

Thanks, I enjoyed that section with the Prof. Ardenne interview and the difficulty convincing Baird that CRT, rather than mechanical TV, was the way to go.

Of course, unlike what was said in that doco, about only the English having the white CRT's and the Germans and Americans having green and yellow, Manfred had his own white phosphor CRT's, I have attached some more images from his book.

He also had very high quality apparatus construction practices, many of his creations not only worked well and were well thought out from the physical science perspective, but were also beautifully built, with the highest standard of craftsmanship, even though they were only "experimental" and not for commercial production. I admire that a lot and I always try to emulate that approach when I build electronic apparatus. So I would say MVA had a significant influence on me.

Beautiful work, all right -- both physically and intellectually. Ever since I got seriously interested in television history I recognized VonArdenne as one of the (mostly unremembered) TV pioneers. I see that Puckle's translation of MVA's book is in the NC State University library not too far from me. Definitely worth looking into.

Von Ardenne also published a good book on cathode ray tubes, 1939 I think .
I'm pretty sure I have this in my library too.

Hi to all,
Hi ACORNVALVE; Thanks! for the new Von Ardenne book CRT Photos.

For the past months, i have been downloading pdf issues of the British magazine "Television and Short-Wave World, see link below. It is incredible, nearly a century later, to follow TV progress month by month from 1928 to the Post-War years. The magazine also covers US/German/French/Italian TV progress :

https://worldradiohistory.com/Televisio ... r_Page.htm

The Feb 1939 issue has a very interesting article by Von Ardenne on light modulators for high-brightness projection TV. To sum it up, all the ingredient of the future oscilloscope Storage CRT are there :

Yes, it is quite amazing to be able to read through those old magazines, I could go through those for hours. Interesting to see the Baird mechanical TV apparatus in a display case, already in a "Science Museum" in 1928. And we think new technology becomes obsolete quickly these days.

Also looking at the equipment, products and services available, it makes us all wish we had a time machine and could go shopping in the 1920's and 30's for electronic parts.

There was a certain type of artwork & engineering in the late 1890's to the late 1920's and machinery of all kinds was very decorative, at least before the Art Deco era of the 1930's came and made things look austere.

Apparatus of the 1920's was often adorned with velvet & fabrics, wood, polished brass & glass. One example that had the "look" was the Grebe MU-1 radio, it captures the magic of that era. Also in Fiction later, the Time Machine from the original movie, though someone once remarked that it looked like something Elton John would have driven through the Everglades.

A while back I decided to make an amplifier for an iPod from 1920's parts and I did my best to make it look like it escaped from the 1920's.

About two years ago I gave a 15 minute talk on pre-war German television to a dozen or so antique television enthusiasts from Northern California. In preparation I looked at much of the material which has been listed in this thread. Of particular interest was the E-1 set with its many advanced features and the television coverage of the 1936 Olympics.

I was surprised that so many in my little audience were familiar with this history and knew more than I about the subject.

Thanks to the new references in this topic, I now have more information. I had never known about the US military reports which evaluated the German electronics and communications developments.

One thing mentioned earlier needs clarification (unless I am wrong): The cameras used at the 1936 Olympics employed technology licensed from RCA and Farnsworth. In return, the American companies obtained the license to produce a white phosphor for the CRTs. Prior to that, RCA used a green CRT.

I am interested in the history of television and the inventors themselves. Thank you jhalphen.

The late Michael Bennett Levy (in the UK) used to claim that his grandfather was the first to create white phosphor for CRT screens.
