Here's an interesting article about the history of national plugs. http://www.iec.ch/online_news/etech/arc _2009/etech_1209/special_1.htm?mlref=etech
If you find this of interest, some of the references and re-directed web pages are also rich with plug history. And, you can find a bit about Edison, Tesla, and Westinghouse. And Harvey Hubbell who invented the separable attachment plug and Philip F. Labre who added the grounding pin.
