But to make it work Amsden actually needed his own radio station.
Florac came up with a design smaller than Amsden had envisioned-
about the size of an eyeglass case and small enough to fit in a pocket.
a New York City businessman named Sherman Amsden started a company called the Doctors' Telephone Service,
one of the very first answering services in the country.
But as the calls poured in and messages piled up, Amsden noticed that many clients-
including some doctors- didn't check for messages as often as he thought they should.
More than 20 years passed before a company called Motorola took Sherman Amsden's concept- pagers that worked all over a city-
and married it with Al Gross's idea of beeping pagers that could be signaled individually.
