Unisphere Biggest World on Earth

Year Published: 1964

Creator: United States Steel

Description: This United States Steel promo film for the 1964 New York World's Fair, entitled "Unisphere Biggest World on Earth", explores the history and significance of world fairs, beginning with early trade gatherings and evolving into global showcases of culture, innovation, and architecture. Iconic events like the 1851 London Exhibition, symbolized by the Crystal Palace, and the 1889 Paris Exposition, marked by the Eiffel Tower, illustrate how these fairs reflected progress. In 1963, construction began on the Unisphere for the 1964–65 New York World’s Fair, envisioned as a symbol of global unity and the Space Age. Made of stainless steel for strength and permanence, the structure presented major engineering challenges, including complex wind dynamics and precise fabrication. Using wind tunnel tests and advanced computer modeling, engineers designed and assembled thousands of custom parts. The Unisphere was completed in just 162 days and featured orbit rings suspended by nearly invisible cables, giving the illusion of floating. It stands as a lasting monument to human achievement, peace, and interconnectedness in a rapidly advancing world. 0:00 Photos show the evolution of world fairs, tracing their origins from early marketplaces to grand international expositions where nations displayed cultural and technological achievements. Notable examples include the 1939 New York World's Fair, the 1904 St. Louis Fair, and the 1889 Paris Exposition. At 1:03, the first official World's Fair is introduced—London’s 1851 Great Exhibition, symbolized by the Crystal Palace, a pioneering structure in glass and iron. As these fairs grew in ambition, so did their architecture. At 1:42, the Eiffel Tower, created for the 1889 Paris Exposition by Gustave Eiffel, is shown as a controversial yet iconic engineering marvel that came to represent world fairs globally. By 2:17, the narrative jumps to 1963, when construction began on the Unisphere in New York’s Flushing Meadows for the upcoming 1964–65 World's Fair. Robert Moses, president of the fair corporation, envisioned a symbol of the Space Age that represented humanity’s shared aspirations and global interdependence. At 2:59, stainless steel was chosen for its strength, beauty, and low maintenance, and the U.S. Steel Corporation was selected to lead the project. At 4:28, the engineering challenges. To maintain visual harmony, no diagonal bracing could be used, meaning the structure had to be both strong and visually light. Because no structure like it had ever been built, wind tunnel testing was conducted at the University of Maryland (5:25) to understand the aerodynamic forces on the open-frame globe. These forces, acting on both sides of the continents, posed unique structural challenges. By 6:20, high-speed computers were used to solve hundreds of simultaneous equations that manual calculation could not handle in time. Fabrication began at 6:55, involving thousands of precision-cut steel components. At 7:54, continents were shaped based on U.S. Army maps and constructed on curved fitting tables. The foundation was laid with 30 anchor bolts (8:39), and the South Pole was the first piece installed. At 9:18, the lower meridians, which would carry the globe’s weight, were assembled, followed by welded sub-sections nicknamed "orange peels." By 10:14, the southern hemisphere was completed in just 83 days. At 11:04, the landmasses were carefully installed—delicate work due to the risk of wind. Then at 12:14, three orbit rings, each weighing three tons, were lifted by cranes and attached using 50 nearly invisible stainless steel cables, giving the illusion they float in space. Finally, at 13:32, the Unisphere was completed in just 162 days. At 13:42, the structure is recognized as a modern counterpart to icons like the Eiffel Tower and Crystal Palace—standing as a bold symbol of peace, unity, and human progress in an expanding world.
