Call a person not a place | TeleSign

40 years ago, on April 3rd 1973, Martin Cooper, then at Motorola, made the first call, using a DynaTAC prototype ‘brick’ style phone, to the landline of Joel Engell, who worked for competitor Bell Labs. As he recalled, “I called and told him, ‘Joel, I’m calling you from a cellular phone, a real cellular phone, a handheld, portable, real cellular phone.’”

Most mobile telephones available before then had been installed in trucks and automobiles, working first off AT&T’s early wireless network, and then off the ‘cellular’ system using multiple transmitters in a hexagonal grid. But as Martin Cooper said, “We believed people didn’t want to talk to cars.”

As far as he is concerned, Motorola ‘brick’ changed the very nature of a phone call. “It used to be when you made a phone call you were calling a place, and now you call a person.”

You used to call a place and now you call a person. I heard Martin say this a few years ago when he key noted some conference I’ve long since forgotten the name of. It seemed so simple and rather obvious at the time, of course you call a person. But, what Martin was saying is fundamental to Mobile Identity. People are attached to their mobile phones and their phone number will connect directly to them.

As Martin once said in a BBC interview, they saw the cellular phone, the personal telephone, as “something that would represent an individual so you could assign a number not to a place, not to a desk, not to a home, but to a person.”

They saw the potential of mobile identity even then. “We knew even in 1973 that someday everybody would have a cell phone,” said Cooper. “We used to tell a joke that someday when you were born you’d be assigned a telephone number, and if you didn’t answer the phone, you died.”

Well of course, ‘died’ is putting it strongly, but Martin was right that nearly everyone would have a cell phone. In fact, we’re nearly there and many online services providers are leveraging the pervasiveness of the mobile phone to protect our online lives.
