One of the Cathedral builders, or real programmers, who laid a lot of groundwork for the merchants of the Bazzar, Ray Tomlinson has a page that all history buffs will want to know about.
If you didn't know, Ray Tomlinson is the first person to invent a method of sending network email. Possibly more important from a cultural perspecitive, Ray is the person who choose to use an "@" (at sign) to separate the user and host parts of the email address.
Ray and Google don't think there should be a hyphen in the word email. I have a feeling Michael Quinion has a different take on the issue.
