Crude amplification was already possible by a combined device of a telephone receiver and a telephone microphone. And there were already fast and sensitive relays, that could give on-off signals. Who knows what Paul has done in those days around 1880. So Jenkins was not the first one, neither Baird, that experimented with the disc, lens or aperture.
Yes you would think the inventor would at least make the disk every thing i have read says he didn't ? he did say in the Television news interview he was very poor and could not even renew the patent for hes invention after a year or carry on studying it lapsed and could not experiment due to that..he had hard times .
He did say he had 2 other inventions a syncing idea and The Picture Mill ....sounds interesting ! he said he was going to put in patents for them but perhaps never did .
This site is pretty much the best pre 1900 inventors inventions on television you may know of ?
http://histv2.free.fr/worth a search here i always come across some thing new on this subject .
BTW i came across another Electric telescope name for their device pre dating Nipkows 1879 perhaps that was the words for television at that time 1870's 1880's heres one from that site image scan below
Its still very hard with the knowledge we have now to make some thing with the better devices parts we have now to use what they had then pretty much electric devices ..
It was already in 1850 that a telefax was demonstrated, but this was seen as picture telegraph. This was only on-off, black and white. That must be the reason that Jenkins experimented with this, a very fast picture telegraph. And it is also not impossible that Paul Nipkow had this in mind when he started some disc experiments. However in his patent he wrote nothing about on-off modulation. That is not unusual, write a patent as broad as possible.
Reading he's words Mr Nipkow was very poor i am sure he would of liked to but he was lucky to eat inventing the nipkow disk in hes head that xmas night he was starving .
Makes you wonder if he ever saw one working apart from reading about television in the newspapers .
Yes they made some wonderful things no electronics all wire motors electricity ....electric fax machine ,sort of the great grandfather of SSTV
