He was responsible for the @ in your address.
Ray Tomlinson - widely regarded as the inventor of the email - has died, aged 74.
The programmer chose the famous @ sign to use in addresses, and is also credited with sending the first email.
He died of a reported heart attack on Saturday (March 5), and his death has led to tributes from the likes of Gmail:
Tomlinson was working at Massachusetts research and development company Bolt, Beranek and Newman in 1971 when he sent a message between two side-by-side computers on the ARPANET system.He chose the @ symbol to connect the username and destination address, which has gone on to be a staple of email and social media.
Since its invention, trillions of emails have been sent and around 4 billion accounts exist.
He admitted that he could not remember what the first message he sent was, saying: "Most likely the first message was QWERTYUIOP or something similar."
He also revealed: "I used the @ sign to indicate that the user was 'at' some other host rather than being local."
Tomlinson was also important in developing services for network mail, such as defining a place to put inbound email on a user's machine, as well as developing an agent to move email between machines.
He also contributed to the development of the email subject line. Source: Digital Spy
Tomlinson was inducted into the Internet Hall of Fame in 2012.
