Thomas Edison is not a good example of an optimit, but he is a good example of a greedy manipulative business man. The shameful fact is that he preyed on the genius of Niolai Tesla and stole his work. Tesla was vulnerable as a recent immigrant to the USA,, and Edison took advantage of him. Please, I understand the misrepresentaiton about Edison is widespread so all the more necessary to corect the misguided admiration, based on falsehoods that this deplorable opportunist perpetuated.
