Ray Tomlinson

Raymond Samuel Tomlinson (April 23, 1941 – March 5, 2016) was a pioneering American computer programmer who implemented the first email program on the ARPANET system, the precursor to the Internet, in 1971; he is internationally known and credited as the inventor of email. It was the first system able to send mail between users on different hosts connected to ARPANET. Previously, mail could be sent only to others who used the same computer. To achieve this, he used the @ sign to separate the user name from the name of their machine, a scheme which has been used in email addresses ever since. Read more on Wikipedia
