Philo Farnsworth? He invented television, in Provo, Utah, and then did the first TV broadcast from San Francisco. He was a visionary, and he died broke. But I really want to tell you about his brother in law, Cliff Gardner. Cliff saw Philo’s drawings, and recognized that this was something that was going to be important, so he said, “I don’t really understand the science behind all of this, but it looks like you’re going to need glass tubes, how would it be if I learned to blow glass and made them for you?”, Philo was inventing the cathode receptor, and glass tubes weren’t really a thing you could buy, “This looks important, and I want to help” is what Cliff said. That’s open source.
