W. Scott Stornetta is considered to be one of the founding fathers of current blockchain technology. Out of 8 citations in the Satoshi Nakamoto whitepaper, 3 of them (4 by some accounts) were of the work of Stornetta and his partner and friend Stuart Haber.
He was a cypherpunk who dedicated his time at Xerox Park and Bell Communications Research to cryptography and distributed computing.
It was a joy to chat with him about the history of the blockchain, uses before bitcoin, and what he refers to as "corporation 2.0" of the future, where we'll start to see all kinds of power structures become decentralized.
