Raymond Tomlinson, the inventor of modern email and a technological leader, died Saturday.

Raytheon Co., his employer, confirmed his death; the details were not immediately available.

Email existed in a limited capacity before Tomlinson in that electronic messages could be shared amid multiple people within a limited framework. But until his invention in 1971 of the first network person-to-person email, there was no way to send something to a specific person at a specific address.
