22 pages. Presentation dated 9-15-65. Attached for your information is a copy of a talk given recently to the Board of Directors of the American Telephone and Telegraph Company.

We were invited recently to make a presentation to the Board of Directors of the American Telephone and Telegraph Company on the "Evolution of the Switchboard." The talk was accompanied by thirteen 35-millimeter slides, using color wherever possible, Starting with a diagram showing why a switchboard is required, various historic types of boards were discussed and illustrated from the first commercial one at New Haven through recent Traffic Service Position installations.

In order that the Directors might observe the TSP at first hand, the meeting was held at the headquarters of the New York Telephone Company. Subsequent to the meeting and the presentation, a brief tour was conducted. First an existing 3CL type office, soon to be replaced by TSP, was visited. The Directors were then taken to the TSP office where the Chief Operator demonstrated the operation at the training position using a specially prepared training tape.

Includes operator speed of service (Slide 8).

10 Men and the Telephone - 1961

FOREWORD

In 1878, when his great invention was only two years old,
Alexander Graham Bell dreamed of a vast telephone network
that would unite every American city, town and village.
He lived to see it happen ... and to see the beginning of a
world-wide system that today makes each and every telephone
a link to almost any place on the face of the earth.
It took a great many men to make Bell's dream come true,
however; men with ideas, imagination, talent and courage.
Bell himself, in his later years, said: "The telephone system
as we now know it is the product of many, many minds, to
whom honor should be given for the wonderful and beneficial
work it has accomplished." This booklet contains glimpses into
the lives of ten of these men ... ten out of the countless thousands
who have helped to create today's far-flung telephone services.
