Recently came across this great article describing the search for Satoshi Nakamoto, the pseudonymous originator of the Bitcoin Network. A number of people are fingered: Gavin Andresen [Here's a great interview of Gavin with Leo Laporte]; some researchers in Trinity College Dublin; the founder of Mt. Gox; and Shinichi Mochizuki, a reclusive mathematical genius.
The argument for Mochizuki has the most plausibility but the evidence is largely circumstantial. Here is an entertaining video of Ted Nelson making the case:
I'm not convinced though. One could make a similar argument that Nakamoto is really Yukihiro Matsumoto, the creator of the Ruby programming language. He is also a Japanese academic with ties to the West and no formal training in economics. Sure, Bitcoin wasn't written in Ruby but that was to cover his tracks. Right?
Joking aside, the best conclusion is that Nakamoto is another manifestation of Anonymous. This group represents the recent phenomenon of masked, technically elite vigilantes out to challenge the corrupt bureaucracy that runs our world.
It would be nice to know who Satoshi Nakamoto really is but the best answer is that he is Anonymous and should remain that way.
