Sometimes private interests obscure the truth in history.
A case in point is that Nicola Tesla was the inventor of the radio, and the US Supreme Court later agreed when it denied Marconi US Army royalties.
Consolidated Electric-GE backed DC power Edison, whereas Morgan backed Tesla.
Ford backed Edison, and they supply money to Smithsonian so Tesla is under represented.
Edison used to publicly electrocute animals with AC power to try and scare away the public from using AC rather than the DC current that he relied on. Most all of our plug in electricity is AC and so are the hydro-electric damns that power the world's cities.
If you are one to point Edison's fame as good for inventors, Edison was never even made a Board Member or vice-president, he was relegated to the highest gopher position of Chief Engineer.
