Help with accuracy of this public record much appreciated.   I will Github it sometime.

This is a catalog of everybody who has been involved with the Ethereum Project in the phase prior to the creation of the Ethereum Foundation, or involved with the Ethereum Foundation after that legal entity existed.

Obviously the list of people who have been involved with the Ethereum Project as a whole since its inception is now an astronomically long list.   That is not the focus here – only on the Ethereum Foundation (lifetime), and on people involved in its pre-historical period, whether or not they actually worked for the EF during that nascent period.

Bold names are still associated with the Ethereum Foundation.
