But I would think that Dr. René Gerónimo Favaloro should be the most well known, but we all know how he ended.
I think you are dead right, except to be truthfull we do not all know how he ended. Sad but true, I had never heard of him, until I checked this out on Wikipedia, and I suspect I am not alone.
You would think you had never heard about him if he was American? Or that he would have left alone like he was by the US?
Again you are right, Americans invented the internet? No it was the Swiss
Americans invented the diesel (oil burning engine) ?Sorry british invention
How about the Hoover? ( I hate that, it is a vcuum cleaner) Welsh invention
Computor? British again
Don't get me wrong some great things have come from the states including the transistor, without which the computor would not be what it is today. All I ask is some credit for the rest of the world.
