Not sure this is the place for this question, but… I have an interest in the history of very early radio technology. There are plenty of sources on who did what when and where, but very little on what technologies (capacitors, wire etc) Marconi,for example, had available to him. I found some Marconi schematics in a rather obscure paper, but nothing else. Any help out there?

  • \$\begingroup\$ There is information available on the history of wire, capacitors etc. Once the nature of wire conductors and capacitors was understood scientists and inventors could easily employ metalsmiths, jewelers, glass blowers and other crafts people to manufacture components. \$\endgroup\$ – Charles Cowie Aug 6 '16 at 19:52

    \$\begingroup\$ I recommend that you read this book: amazon.com/Much-ADO-about-Almost-Nothing/dp/0615139957, it deals with the "history of the electron" (how it was deiscovered etc.) and part of that is related to wireless communication. It will give you insight in the people involved and at what time they made their inventions. From that you can find other relevant information. \$\endgroup\$ – Bimpelrekkie Aug 7 '16 at 15:12
  • \$\begingroup\$ Fake...That looks like a great book. Not sure it's exactly what I'm looking for, but I'm a small-time history buff and I just added it next to my next order. \$\endgroup\$ – Robert Endl Aug 7 '16 at 20:42
