While we may not know who he (or she) was, we know what he did. Satoshi Nakamoto was the inventor of the bitcoin protocol, publishing a paper via the Cryptography Mailing List in November 2008.
He then released the first version of the bitcoin software client in 2009, and participated with others on the project via mailing lists, until he finally began to fade from the community toward the end of 2010.
Nakamoto worked with people on the open-source team, but took care never to reveal anything personal about himself, and the last anyone heard from him was in the spring of 2011, when he said that he had moved on to other things.
Oh yeah, I've heard it
