They forgot the Refrigerated Truck

10 Inventions You Didn’t Know Were Created by African American Inventors

I still don't know it. Most of these 'inventions' relate merely to patents, which for the sake of argument, I'll propose never led to any practial or commercially viable products. Show me otherwise.

What could be more practical than the universally used Traffic Light? Not sure how it benefitted the inventor, but it remains part of our everyday lives.

Even the Refrigerated Truck mentioned in the subject line is depended upon to transport frozen goods, again positively affecting our everyday lives.

History of traffic lights

The real question must surely be - what, if anything, was original or innovative about Morgan's design? Do we have proof that General Electric paid him $40,000? And if they did, were they really buying his system or was it essentially a legal measure to close out competition and promote their own models?



I don't think anyone invented the 'refrigerated truck' in the sense you mean. Transport and refrigeration are two such general systems/technologies that the idea of combining them to transport perishable goods seems too obvious to be considered an invention or inspiration. But if thought of a series of technological developments then it's possible that your man played a role. Of whom do you speak?

Don't recall the guy's name. Afterall, I only saw that on a documentary about 25 to 30 years ago.

All's good.
