Welcome to The Telecommunications History Group (THG), where you can pursue scholarly or personal research, view museum exhibits or tour a historical telephone company building. THG collects, preserves, and interprets the unfolding history of telecommunications industry. We have facilities in Denver, Colorado and in Seattle, Washington.



THG is a non-profit organization funded by membership dues, research fees and grants. We maintain and operate one of the nation's largest privately held telecommunications archives, operate two museums and conduct educational programs on telephone history.

Our website is designed to provide online visitors with information about The Telecommunications History Group's collections, its programs and its services. We hope the website will encourage you to visit one of our facilities, but it is designed to allow those at a distance to discover and enjoy our collections, as well. Be sure to visit our Virtual Museum to learn more about the history of the industry.

Our websites and our online resources are constantly expanding, and we welcome your comments on the types of information that you need to pursue your research, discover information about upcoming programs, or use our facilities.

With great sadness we report the passing of Robert K. Timothy. Bob was a telephone man from 1946 when he became a coin collector for Mountain States Telephone & Telegraph Company, until his retirement as its President in 1982. All who knew and worked with Bob loved and respected him.

Bob was also a THG board member, and one of our most ardent supporters - the Robert K. Timothy Library in the THG Archives was named in his honor. Bob requested that in lieu of flowers, contributions be sent to the Telecommunications History Group.
