The centennial commenced on the morning of May 10, 1876, with a seemingly providential break in the rain. The program—which included lengthy speeches on the marvels of American growth, and an orchestra playing an array of national anthems from around the world in addition to Richard Wagner’s made-to-order “American Centennial March”—had swelled to fit the exhibition’s hybrid nature. What had originally been intended as a national birthday celebration had been joined to a World’s Fair displaying the material wonders of the Industrial Age. The ensuing event, which ran for the next six months, was designed to show how happily material progress and national glory could be made to blend. Financed through a mix of public and private money and enabled in no small part by the backroom maneuvering of the Pennsylvania Railroad boss Thomas Scott—whose lines stood to benefit from the traffic—it was a perfect Gilded Age confection.
The massive glass-and-iron main building was the largest man-made structure on the planet at the time, encompassing more than 21 acres of floor space. It was just one of some 200 buildings across the site, many of them sparkling architectural showpieces dedicated to, among other things, pomology, photography, brewing, dairy processing, and glassmaking. Nations and states commissioned their own buildings—a Tudor mansion for England, a residence and “bazaar” for Japan, a “cottage” for Connecticut, a Spanish-moss-fringed log cabin for Mississippi. Fairgoers could see some of the first mechanical typewriters in action, sample Charles E. Hires’s root beer, hear the ear-splitting “annunciator” of Western Electric’s new heat-sensitive fire alarm.
When the exhibition closed in November, at least 9,799,392 people—about 20 percent of the U.S. population—had visited, including a 79‑year‑old man who walked from New Albany, Indiana, with the aid of a stick cut and carved in the 1810s. Most of those who went were delightfully overwhelmed. In a letter home, a young woman from Providence, Rhode Island, struggled to find words for what she saw: “Dear Mother, Oh! Oh!! Oh!!! Oh!!!! Oh!!!!! O-o-o-o o-o-o-h!!!!!! Your affectionate daughter, Mary.” Even Alexander Graham Bell, whose newly invented telephone was one of the fair’s sensations, said that it was all “so prodigious and wonderful that it absolutely staggers one.”
Behind the unspeakable wonders of Machinery Hall stood a world of labor—dirty, dangerous, and low-paid—that constituted a grave threat to the values of the republic. Such toil clashed with Jeffersonian ideals that equated independent proprietorship of farms and shops with the moral virtue necessary for honest citizenship. Just before the Civil War, Abraham Lincoln had said that men performing wage labor for more than a short stint suffered from “either a dependent nature which prefers it, or improvidence, folly, or singular misfortune.”
