Satoshi Nakamoto
On 31 October 2008, an anonymous figure publishing as emailed a whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System to a cryptography mailing list. It proposed solving the double-spend problem without a trusted third party, using proof of work and a public timestamped ledger. On 3 January 2009, the same operator mined the — the first block — embedding the Times bailout headline described above.
Satoshi's real identity remains unknown. The name could be one person or a group; the project's early code and forum posts stopped by 2011. The anonymity is itself part of the design philosophy: a money system with no founder to pressure, subpoena, or compromise.

Identity unknownHal Finney: the human face of early Bitcoin
Hal Finney was a cypherpunk, a cryptography engineer, and the first person besides Satoshi to run Bitcoin. He received the first Bitcoin transaction — 10 BTC from Satoshi, in January 2009. Finney chronicled the early days in a famous 2013 post, Bitcoin and Me, written after an ALS diagnosis that left him paralyzed; he described sitting in his "little office" mining Bitcoin on his computer in those first weeks, watching a new economy boot up.

Hal Finney
Cypherpunk; first Bitcoin recipient, early developer, and the human face of the project's founding weeks.
Finney is the clearest example that Bitcoin began with real, named people motivated by the cypherpunk vision of privacy-preserving money — not as an abstract technical exercise. His story is a useful antidote to the idea that crypto "came from nowhere."
