For what it’s worth, Philo Farnsworth and John Logie Baird were friendly with each other. I was lucky to know Philo’s wife Pem very well in the last part of her life, and she spoke highly of Baird as a person.
David Sarnoff and RCA was an entirely different matter, of course…
One of his electro-mechanical units was on display in Victoria, Australia. Most amazing assemblage, you can sort-of get the idea from things.
I read online that at his end, Baird was proposing a TV scan-rate we'd class as HD quality, which lost out to a 405 line standard (which proceeded 625/colour)
There is also a quality of persistence in his approach to things, he was the kind of inventor who doesn't stop inventing.
