Hertz

I think Roberto read about some experiments made by Heinrich Hertz with the crookes tube that's why he included it on patents and such. Reading the patents and info I don't really know if he knew what he was doing, he seems to always end recurring to the "photophone" in his more detailed explanation. What I think he "invented" was a megaphone-photophone system, and later patented that spark wave generator wich apparently worked. The reports made by the magazines were probably related to the photophone and megaphone. Mirad1000 (talk) 04:52, 21 February 2023 (UTC)[reply]

Reposting of deleted text that was removed from main page

The following was removed from the main page on February 15, 2024. I am reposting it here because it appears to be a common opinion in Brazil, but more appropriate for the Talk page:

He had many technical and financial difficulties to develop his research, he worked most of the time alone and found a lot of resistance and disbelief on the part of authorities and the population, which prevented his recognition in life from being broader, but in certain spheres his stature scientific research was duly appreciated and it is known that he rejected opportunities to publicize its inventions. Thus, the popular idea that was formed around him as a persecuted, wronged and suffered scientist facing an insensitive and obscurantist world, is a partial truth. His biography still has many gaps and only part of his scientific legacy has been studied, with a lot of autograph documentation still to be explored. In any case, in Brazil he has already received a series of official honors and recognitions. He is honorary citizen of city of São Paulo, patron of Science, Technology and Innovation in the municipality of Porto Alegre, patron of Brazilian radio amateurs, and in 2012, by presidential decree, his name was inscribed in the Tancredo Neves Pantheon of the Fatherland and Freedom

It was removed because it is un-referenced, opinion, and does not summarize content in the body of the article (see MOS:LEAD). It may be true but the lead needs to follow the body and the body material requires references.

I have also removed these claims (again) to talk. We can not make claims about someone by trying to translate and interpret non-English primary sources. The claim in the lead, as written, is probably wrong since it combines the claim of "developing long-distance audio transmissions" with "radio signals". The body of the article (and the available sources) do not support this claim. de Moura at some point added, or described, a coherer based radio bell signal, not radio voice transmission. We have de Moura proposing using radio voice transmission in a patent completed before 1903 but there is no reference that he ever accomplished this and that date would be after Fessenden's 1900 voice transmission.
