In many ways, the history of humankind is the story of how we communicate. One way to mark the important epochs of our past is to note the appearance of new technologies that have transformed the way we share news and information with each other. According to this view of history, the heroes of human progress must include the scientists and engineers who fundamentally transformed society with inventions that changed the way people keep in touch with one another. here was Samuel B. Morse, for example, inventor of the telegraph. And telephone inventor Alexander Graham Bell. Next came Guglielmo Marconi, who sent the first wireless communication. After Marconi, came Ray Tomlinson. Although he doesn’t get much publicity, Tomlinson in 1971 wrote the first e-mail program and sent the first e-mail message.
