I stumbled across this video series posted on YouTube by user ‘Bakelite N’ Waffles’. He had stated that he got the videos from the Smithsonian Institute Archives and then edited some of the delays out of the videos. It is a fascinating look at Eugene Stoner and his thoughts behind his work. Below is the series of 8 videos. Enjoy.
FWIW: The same YouTube user has also posted the Smithsonian’s videos from the meeting between Stoner and Kalashnikov.
