2) Hal Finney receives the first Bitcoin transaction from Satoshi Nakamoto

Here is a little bit about Hal Finney himself:

Here is the transaction in question:

He also happened to be running the first node other than Satoshi.

Here you can read more about him from his own Bitcointalk profile.

Bitcoin and me (Hal Finney):

Hal Finney says:

After a few days, bitcoin was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me.

In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there at the beginning. It’s one of those glass half full half empty things.

The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there.

As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they’ll be worth something to my heirs.”

Unlike Hal, szabo has never given any sort of detailed denial that he is satoshi. He has denied it of course, but he didn’t write some narrative about it like Hal did”

He was an early bitcoin user and received the first bitcoin transaction from bitcoin’s creator Satoshi Nakamoto. Finney lived in the same town for 10 years that Dorian Satoshi Nakamoto lived, adding to speculation that he may have been Bitcoin’s creator. Finney denied that he was Satoshi Nakamoto.

So either Hal is a big fat liar or he isn’t satoshi.

I am not too sure whether he got sick around the same time Bitcoin was published, but it also adds a little to the mystery.
