Hal Finney

Hal Finney was a cryptographer and PGP developer who saw what most missed. On January 12, 2009, Satoshi Nakamoto sent him ten Bitcoin, the first transaction in the network's history. He ran the second node, the only one operating alongside Satoshi himself. Diagnosed with ALS that same year, he kept coding. From his wheelchair, in a body shutting down, he wrote code and answered emails until the paralysis took his hands. He died August 28, 2014. His body is cryopreserved at the Alcor Life Extension Foundation. He is still, technically, not finished.
