At that time, electronic messages could only be sent to users on the same computer.<\/div>\n<\/div>\n<div class=\"x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a\">\n<div dir=\"auto\">His breakthrough came with a simple but ingenious solution\u2014using the @ symbol to separate the user name from the host computer name. This user@host format remains the global standard fifty years later.<\/div>\n<\/div>\n<div class=\"x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a\">\n<div dir=\"auto\">Tomlinson&#8217;s first test message was sent between two computers sitting side by side in his lab. While he later admitted he couldn&#8217;t remember the exact content of that first message, he suggested it was probably something like &#8220;QWERTYUIOP&#8221; or &#8220;testing 123.&#8221;<\/div>\n<\/div>\n<div class=\"x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a\">\n<div dir=\"auto\">What&#8217;s remarkable is that Tomlinson wasn&#8217;t assigned to create email. He developed it as a side project while working on other ARPANET protocols. His supervisor only learned about it after the fact.<\/div>\n<\/div>\n<div class=\"x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a\">\n<div dir=\"auto\">The modern controversy surrounding email&#8217;s invention comes from Shiva Ayyadurai&#8217;s claim to have invented email in 1978. However, most computer historians maintain that Tomlinson&#8217;s 1971 innovation was the true birth of networked electronic mail.<\/div>\n<\/div>\n<div class=\"x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a\">\n<div dir=\"auto\">While email has evolved dramatically since those early days, Tomlinson&#8217;s core innovation\u2014enabling messages to travel between separate computers via a network\u2014remains the foundation of electronic communication used by billions daily.<\/div>\n<\/div>\n<div class=\"x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a\">\n<div dir=\"auto\">Sources: Internet Hall of Fame, Boston Magazine, Smithsonian Institution<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>In 1971, a 30-year-old engineer named Ray Tomlinson sat at his terminal at Bolt Beranek and Newman (BBN) and changed communication forever.
