Raymond Tomlinson (born 1941) is a programmer (credited with the invention of '@' in e-mails) who implemented an email system in 1971. It was the first system able to send mail between users on different hosts connected to the ARPAnet. To achieve this, he used the @ sign for sending email ^*.

The first email sent by him is not preserved and had content he describes as insignificant, something like "QWERTYUIOP". This is commonly misquoted as "The first e-mail was QWERTYUIOP" ^*

At first, his email messaging system wasn't thought to be a big deal. When Tomlinson showed it to a colleague he said "Don't tell anyone! This isn't what we're supposed to be working on." ^*

He is a graduate of Rensselaer Polytechnic Institute and a long-time employee of BBN.

Career

---

Tomlinson was born in Amsterdam, New York, but his family soon moved to the small, unincorporated village of Vail Mills, New York. He attended the Broadalbin Central School in nearby Broadalbin, New York. He attended Rensselaer Polytechnic Institute in Troy, New York where he participated in the co-op program with IBM. He received a Bachelor of Science degree in Electrical Engineering from Rensselaer in 1963.

After graduating from RPI, he entered the Massachusetts Institute of Technology to continue his electrical engineering education. At MIT, Tomlinson worked in the Speech Communication Group and developed an analog-digital hybrid speech synthesizer as the subject of his Master's thesis. He received a Master of Science in Electrical Engineering degree in 1965.

In 1967 he joined the technology company of Bolt Beranek and Newman where he helped develop the TENEX operating system including ARPANET Network Control Protocol and TELNET implementations. He worked on a file-transfer program called CPYNET to transfer files through the ARPANET. Tomlinson was asked to change a program called SNDMSG, which sent messages to other users of a time-sharing computer, to run on TENEX. He added code he took from SNDMSG to CPYNET so messages could be sent to users on --other-- computers -- the first email.

Awards and Honors

In 2000 he received the George R. Stibitz Computer Pioneer Award from the American Computer Museum (with the Computer Science Department of Montana State University). In 2001 he received a Webby Award from the International Academy of Digital Arts and Sciences for lifetime achievement. Also in 2001 he was inducted into the Rensselaer Alumni Hall of Fame. In 2002 Discover Magazine awarded him its Innovation Award. In 2004, he received the IEEE Internet Award along with Dave Crocker.
