The first long-distance car-to-car phone conversation occurred on this date in 1946. Alton Dickieson and D. Mitchell from Bell Labs, along with future AT&T CEO H.I. Romnes, were part of a team that worked more than a decade to create what they termed a “primitive wireless network” capable of transmitting phone calls. Initially just a huge “party line” (subscribers had to listen for someone to be on the line before placing a call), the network was used sparingly, as it could not handle large volumes. It was also much less than “mobile,” as the required equipment weighed in at 80 pounds.
