Bitcoin and me (Hal Finney).
When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them.
Satoshi Nakamoto is not only early Bitcoin miner, Hal Finney is one of them.

Hal Finney was not Satoshi Nakamoto with some of his analyses to prove it.
