Today we are celebrating both the dawn of networked email, and the person who sent the first email, Ray Tomlinson. In October, 1971, Ray sent the very first networked email. To be sure, the computer to which he sent it was barely 3 feet away from the computer from which he sent it, and yes, he had sent it to himself, but nonetheless, it was groundbreaking. Prior to that some computers had a rudimentary 'email' messaging system through which one person could leave a 'mail' message for another person, but only on the same computer (sort of like a local dropbox). Sending one email to another computer was a Very Big Deal. It was also Ray who decided that there should be the "@" between the username and the domain (web address) of the email, and the rest, as they say, is history.
