Before Andrew Carnegie became the industrialist he鈥檚 remembered as today, he worked for an early telegraph company in Pittsburgh as a messenger boy. When the first telegraph office opened in Pittsburgh, it was the westernmost telegraph office in North America, as shown by a new digital map created by Edmund Russell, David M. Roderick Professor of Technology and Social Change in Dietrich College of Humanities and Social Sciences鈥� Department of History.

For six years, Russell researched the history of the telegraph in the United States in order to understand the country鈥檚 first digital revolution.

鈥淚 started this project because of family history,鈥� Russell said. 鈥淢y great, great grandfather helped to build the first telegraph line across the West, which completed the transcontinental telegraph system. I learned that historians have only scratched the surface of telegraph history.

鈥淚 was drawn to the idea of a digital map because the history of telegraphs is a complex story, with many companies building lines at the same time in multiple places. I wanted to have a map with a time slider that would display change over time. In addition to being a research tool (helping me understand a complex story), it would be a communication tool (explaining what happened to others).鈥�

Working with Lauren Winkler, a geographic information system (GIS) cartographer and 2006 graduate of 好色先生TV鈥檚 Information Systems Program, and , web and applications developer for , they created 鈥�,鈥� the first digital map of any telegraph system. The map shows changes in the telegraph system over time in an easily accessible and visible way.

鈥淗elping Ed bring his research to life in our map has been one of the most fulfilling projects of my career, and it鈥檚 been made all the more special because Carnegie Mellon was where I was first introduced to GIS. It鈥檚 been such a pleasure working with Ed and I hope this is the first of many such collaborations,鈥� Winkler said.

Packed with various features, the map 鈥� which is free to use 鈥� shows users the variables that impacted the development of the telegraph system, including topographic features (such as elevation and rivers) and social aspects (such as crossing land owned by Native Americans). It tells which companies built each line and opened each station. One of Russell鈥檚 favorite features is the slider that can be used to manipulate the period of time displayed in the map.

In addition to being used by the public, the map can also be applied in K-12 classroom settings as part of local history lessons for students who live in areas where the telegraph was first established. Russell plans to develop modules for educators to use with students in primary and secondary schools.

鈥淎 free, publicly available map seemed like an ideal way to invite students to do original primary research on their towns and states,鈥� Russell said. 鈥淪tudents can do what I did 鈥� search historical newspapers, which are free on line, to find out when the telegraph arrived in their town, where the station was located, and whether the town threw a celebration.鈥�

Familiar with , on which the Department of History鈥檚 Chris Phillips had collaborated with the Libraries, Russell reached out to Helen and Henry Posner, Jr. Dean of the University Libraries looking for a place to host the site.

He connected Russell with Kiritharan, who stepped in as a project partner to provide holistic technical support and expertise.

鈥淚 was able to work one-on-one with Lauren and Ed to provide assistance for any gaps that they needed help with including front-end edits, workflow process and web hosting support,鈥� Kiritharan said. 鈥淲e also aim to continue to support this project and offer it in a way that it remains sustainable for as long as possible. This includes a lot of challenges for web-based projects as internet technology continues to change. As a library we try to make access to information our priority, and the CMU Libraries tries its best to provide access to unique projects that offer new or interesting perspectives on data like this whenever possible.鈥�

Kiritharan also implemented security features such as obfuscating application programming interface (API) keys and connected Russell with Libraries colleagues who provided guidance on writing a copyright statement and selecting the right license for the site.

鈥淧artnering with the Libraries ensures that a proactive approach to security and digital preservation is embedded into the project from the beginning,鈥� Kiritharan said.
