Tomlinson was best known for choosing the @ symbol to indicate a message should be sent to a different computer on a network. He also led development of standards for the from, subject, and date fields found in every email message sent today.
News of his death began circulating on a BBN alumni email list tonight. Another networking legend, TCP/IP inventor Vint Cerf, confirmed it via Twitter.
From today on, his email will hard-bounce with "user unknown".
