He was the head of the team that invented, the handheld cell phone. Cooper has been quoted as saying (of the first such device) "The battery lifetime was 20 minutes, but that wasn't really a big problem because you couldn't hold that phone up for that long" (it weighed about 2.5 pounds).
It's probably worth noting that this was not the first cellular phone; it was just the first one that was "small" enough to be practical as a handheld device (prior to that, they'd been intended for installation in cars).
