When many people hear
the name of Bell Telephone Company, the first thing they think of is the
court-directed breakup of Bell System into what became known as "Baby
Bells" after being sued for monopolistic policies. What is too often
forgotten - or more likely never realized - is the immense role Bell played in
the building of America into an industrial and technology giant. Vintage
magazines like this 1949 issue of Radio-Electronics as well as many
other types including The Saturday Evening Post, Popular Mechanics,
Family Circle, and many other publications found in homes, contained
full-page advertisements by Bell Telephone Laboratories promoting their work and
reminding subscribers of how their hard-earned money was being invested on
improvements. Along with the Interstate Highway System, America's robust,
dependable, and high quality personal communications via telephone was accorded
major credit for innovation and production. They are two major components of the
logistical system needed to support the effort.

Another Score in the Battle of the Inches
It takes many costly buildings to house your telephone system. Every inch saved
helps keep down the cost of telephone service. So at Bell Telephone Laboratories
engineers work constantly to squeeze the size out of telephone equipment.
In the picture a new voice frequency amplifier is being slipped into position.
Featuring a Western Electric miniature vacuum tube, tiny permalloy transformers,
and special assembly techniques, it is scarcely larger than a single vacuum tube
used to be. Yet it is able to boost a voice by 35 decibels. Mounted in a bay only
two feet wide and 11 1/2 feet high, 600 of the new amplifiers do work which once
required a room full of equipment.
This kind of size reduction throughout the System means that more parts can be
housed in a given space. Telephone buildings and other installations keep on giving
more service for their size - and keep down costs.
The new amplifiers, which will soon be used by the thousands throughout the Bell
System to keep telephone voices up to strength, are but one example of this important
phase of Laboratories' work.
