Ernest O. Lawrence invented the color TV but he was better known for his work with Dr. Edward Teller (father of the hydrogen bomb).
If you want to talk about inventions, the Nazi's were flying jets and had prototypes for the Space Shuttle, ICBM's and Stealth bombers/fighters long before the USA. Their aerospace industry was easily 50 years ahead of the rest of the world. When the war ended, some of the scientists and engineers went East. Some went west. We all know the rest of the story.
Easily 50 years... hmm... I'd take the 1993 US Air Force against the 1943 German Air Force every day of the week and twice on Sundays. I'd even give odds.
It never ceases to amaze me how a people will take collective credit for the accomplishments of individuals.
