Fascinating documentary on the history of the REVOLUTIONARY transistor

Fascinating documentary on the history of the REVOLUTIONARY transistor. Three scientists with completely different personalities changed the world forever ( reflection as I type on my computer ). I will look for a transcript as I had trouble following certain technical details. When Shockley became controversial with seeming racist theories I wrote a letter to the Providence Journal which they titled " Let Shockley Speak " . My attitude toward the FREE SPEECH ,FREE THOUGHT tradition of Western Civilization has never changed.
