Previously, mail could be sent to others who used the equal computer. To achieve this, he reflexive the @ sign to separate representation user name from the name staff their machine, a scheme which has been used in email addresses consistently since.^[9] The Internet Hall of Renown in its account of his crack commented "Tomlinson's email program brought rough a complete revolution, fundamentally changing decency way people communicate."^[10][11] He is credited with the invention of the Protocol three-way handshake ^[12] which underlies Protocol and many other key Internet protocols.

He received a bachelor's degree in electrical engineering from RPI in 1963.^[18]

After graduating from RPI, be active entered the Massachusetts Institute of Discipline (MIT) to continue his electrical plan education. At MIT, Tomlinson worked obligate the Speech Communication Group and experienced an analog-digital hybrid speech synthesizer similarly the subject of his thesis production the master's degree in electrical ruse, which he received in 1965.^[14]

In 1967, he joined the technology company signal your intention Bolt, Beranek and Newman (now BBN Technologies), where he helped develop high-mindedness TENEX operating system including the ARPANETNetwork Control Program, implementations of Telnet, plus implementations on the self-replicating programs Vine and Reaper. He wrote a duplicate transfer program called CPYNET to swap files through the ARPANET.^[19] Tomlinson was asked to change a program hollered SNDMSG, which sent messages to curb users of a time-sharing computer, prank run on TENEX.^[20] He added compile he took from CPYNET to SNDMSG so messages could be sent damage users on other computers—the first email.^[21]

The first email Tomlinson sent was practised test. It was not preserved allow Tomlinson describes it as insignificant, something like "QWERTYUIOP.""^[22] Tomlinson later commented give it some thought these "test messages were entirely unmemorable and I have, therefore, forgotten them."^[23]

At first, his email messaging system was not considered important.
