I've always wondered about the extent of Tesla's work, suspecting that he was far, far more ahead of his (and our) time than we know. This plea for the release of his seized papers has, I think, an unfairly negative slant regarding J.P. Morgan, but otherwise seems on target. For certain, the FBI raced to Tesla's hotel suite immediately upon his death and took everything. Where are his papers? It's a good question.
PBS has a nice site regarding their special on Tesla.
