Denison Herald
July 27, 1938

When the first issue of the Denison Herald came off the press 50 years ago, the city's telephone exchange was six years old.  According to available records, telephone service came to Denison in 1882 - just seven years after Dr. Alexander Graham Bell in his attic laboratory in Boston has spoken the first words transmitted over wire.

Denison's first telephone exchange "had sufficient capacity to serve about 50 subscribers, " according  to an early report.  However, when the telephone system was a year old, additional equipment was installed which increased its capacity to 75 subscribers.

In 1902 a new switchboard and other central office apparatus was placed in service to make 600 lines available for telephone subscribers.  The equipment was installed in a new telephone office at 218 West Main street.

Five years later the telephone system had outgrown its quarters and moved to a new office where equipment which increased the switchboard facilities to a possible capacity of 5,000 lines was installed.

The present telephone building at 500 West Chestnut street was erected in 1927 and a completely new switchboard and associated central office apparatus installed.
