In the unlikely event: danger and the transportation revolution in America

This study is a cultural history of danger, disaster, and steam-powered transportation in nineteenth-century America. The application of steam power to transportation, a globally transformative innovation, had particular influence in the early United States. A vast American continent with difficult terrain and poor infrastructure posed significant challenges, both to individual mobility and to a nation eager to build an integrated economy, a unified culture, and a functional republican government. Steamboats and locomotives offered an apparent solution, their speed and power seemingly shrinking distances between places and expanding mobility and access across space, a process contemporaries and scholars have described as a sort of space-time compression. However, these machines that overcame space also blew up, caught fire, wrecked, collided, derailed, and broke down, killing tens, and often hundreds, of Americans at a time. This dissertation analyzes the ways Americans encountered, interpreted, and adapted to these new dangers, all the while making the technology that created them an ever more essential aspect of their lives. I argue that Americans’ responses to disasters, filtered through the transportation and communication networks created by steam power, constituted a deep, shared reflection about the nature of expanded mobility in a fast-evolving modern America. Though few suffered disaster directly, Americans collectively framed the danger of steam as both a profound national problem and an evocative symbol of modernity. Through public conversations mediated by print, Americans identified susceptibility to danger as inherent to high-speed travel, and, alongside practical safety measures, developed distinctly modern cultural adaptations to understand and manage that danger. By century's end, Americans had cultivated a modern mentality on mobility, technology, and danger: though most Americans never experienced disaster they were intimately aware of it, and though familiar with catastrophe they understood it as unlikely and accepted it as a feature of their modern technological lives.
