te City, Zachary Brodt explores Western Pennsylvania's representation at Chicago's Columbian Exposition, the first major step in demonstrating that Pittsburgh was more than simply America's crucible--it was also a region of developing culture and innovation. The 1893 Columbian Exposition presented a chance for the United States to prove to the world that it was an industrial giant ready to become a global superpower. At the same time, Pittsburgh, a commercial center that formerly served as a starting point for western expansion, found itself serving as a major transportation, and increasingly industrial, hub during this period of extensive growth. Natural resources like petroleum and coal allowed Western Pennsylvania to become one of the largest iron- and steel-producing regions in the world. The Chicago fairgrounds provided a lucrative opportunity for area companies not only to provide construction materials but to display the region's many products. While Pittsburgh's most famous contributions to the 1893 World's Fair--alternating current electricity and the Ferris wheel--had a lasting impact on the United States and the world, other exhibits provided a snapshot of the area's industries, natural resources, and inventions. The success of these exhibits, Brodt reveals, launched local companies into the twentieth century, ensuring a steady flow of work, money, and prestige.
