As great inventions go, e-mail had a rather ho-hum beginning back in 1971. In fact, Ray Tomlinson, the American engineer considered the ``father of e-mail, can t quite recall when the first message was sent, what it said, or even who the recipient was.

``I have no idea what the first one was, he told Reuters. It might have been the first line from Lincoln s Gettysburg Address for all I know. The only thing I know was it was all in upper case.

Tomlinson, principal engineer at Cambridge, Mass.-based BBN Technologies, finds himself in the spotlight again after all these years, having to answer questions about the computer program he designed as it reaches its 30th birthday in the coming weeks.

He modestly calls his baby ``no major tour de force. It was just 200 lines of code, he says. And the inspiration -- one computer program to enable file transfers and a second crude messaging program -- already existed, he said.

But the programs had their flaws. For example, the message program only enabled a user to send a communique to a colleague s mailbox as long as that mailbox was located on the same computer as the sender s.

Tomlinson got around this by creating remote personal mailboxes that could send and receive messages via a computer network. He also conceived the now-famous ``+ symbol to ensure a message was sent to a designated recipient.

The end product, he said, was simply the combination of the two existing programs, enabling a person to send a message for the first time to a specified computer user on any computer hooked up to the ARPA Net, the predecessor to today s Internet, developed by the U.S. Department of Defense (news - web sites).
