September Online Meeting of the Early Television Museum Community

September 28 at 8 PM EDT

Our September Meeting will feature four segments: first, Steve McVoy will update news of the Early Television Foundation, followed by a look at an item in the museum's collection. Mike Molnar will give a presentation on early electrical meters. Then we will have an open topic discussion. Feel free to introduce any topic you are interested in.

I did a little quick research on Arthur Bronwell, who was mentioned in the discussion as inventor of a color picture tube.
https://en.wikipedia.org/wiki/Arthur_Bronwell

His paper is summarized in a Dec 1947 report on the National Electronics Conference in Chicago, but without diagrams or enough detail to fully understand it. He proposed having a single electron gun and three transparent screen layers of different phosphors somehow insulated from each other, plus a fourth electrode layer, all of which could have a switched potential that somehow would allow only one layer to fluoresce at a time. It was proposed to do switching at either field or line rate. This summary is repeated in Abramson's second book, History of Television 1944-2000, with no further details. It is not clear if Bronwell ever created a physical model. My guess is that it never went beyond a proposal on paper.
