The meeting’s themes will be “Reform(ed) Technologies” and “Circulation of Technology.” At a moment when decaying infrastructure is a major topic of public discussion and large promised investment, Pittsburgh looks the right place for historians of technology to reconsider linear tales of innovation or destruction. Some sessions focus on the ways in which technologies are reformed and on the historical development of technologies for reform. Environmental technologies are an obvious topic, but the theme also embraces topics such as urban renewal, new uses of old technologies, and issues of maintenance. Deadline has passed!
