When great is right and wrong
Robert William Kearns was a great, decent man. Ford was and is a great company with brilliant and decent engineers. Ford management, same as any corporate management are cunning and untrusting scoundrels. They all where and still are.
Kearns was brilliant engineer and dumb businessperson. Total nonsense was his desire to become manufacturer. Same nonsense and naivety was giving his proprietary device to anyone else prior to signed agreement in advance.
He horribly sacrificed life of his family. From the point of family, he should have reconciled first time. From the point of justice and other inventors and innovators, he is a hero. He deserved some civilian version of Medal of Honor for valor and stand out.
Such life story is perfect lesson and should be mandatory for any living inventor or innovator to see this movie.
