How a small Ohio city once powered the world's most ambitious engineering feats
In short: Marion, Ohio, was once the industrial engine of America. In 1911, this city manufactured 80% of the nation's heavy-duty earth-moving equipment. From digging the Panama Canal to transporting massive Saturn V rockets for NASA, Marion's steam shovels literally reshaped the landscape of the twentieth century and beyond.
The industrial dominance of Marion began with the Marion Steam Shovel Company, which became a global powerhouse in heavy machinery. Its equipment was essential for monumental infrastructure projects, including the construction of the Panama Canal and the Holland Tunnel. This manufacturing prowess reached its peak in 1911, when the city produced the vast majority of the country's steam shovels. Decades later, the company—renamed Marion Power Shovel—pivoted to aerospace, manufacturing the massive crawler-transporters used by NASA to move Saturn V rockets to launch pads for the Apollo program.
Beyond heavy machinery, Marion evolved into a diverse manufacturing hub. Today, it hosts the world's largest clothes dryer manufacturing facility, operated by Whirlpool, which produces over 20,000 units daily. The city also maintains a significant presence in the steel industry through Nucor Steel, the largest producer of rebar and signposts in Ohio. This industrial legacy is supported by the city's strategic location as a rail center, with major intermodal freight facilities connecting local production to national markets.
The city's identity is deeply rooted in its history and geography. Situated on flat land formed by glacial till 12,000 to 14,000 years ago, the region possesses highly productive soil, which historically supported a robust agricultural sector, particularly in corn and popcorn production. This agricultural heritage is celebrated at the Wyandot Popcorn Museum, the only institution in the world dedicated to popcorn memorabilia. Meanwhile, the city's cultural landscape is anchored by the 1928 Palace Theatre, an atmospheric venue designed by John Eberson that remains one of only 16 such theaters still in operation today.
