Only had very brief history of Tesla in school, definitely thought he was a crazy scientist from that schooling.
However since I went into the digital electronics field he came up more often in discussion so it can depend on your schooling.
Now we have whole History channel episodes about him and him being taken advantage of by his employers, repressed, ideas stolen, all his work taken by the FED, some still missing...
He was way ahead of his time and it probably scared people back then.
