I was under the impression that Edison accidentally invented the vacuum tube as a result of a failed light bulb experiment, never finding an application for the technology but filing a patent for it nonetheless (just in case). Is that not the case, Randy? I know it's still called the "Edison Effect", but isn't the patent Thom's as well?
