America’s 150th Birthday Celebration Was Deemed the Nation’s ‘Greatest Flop.’ What Went Wrong With the Sesquicentennial?

Philadelphia politicians hoped to replicate the success of the 1876 Centennial Exposition. Instead, the 1926 world’s fair lost millions of dollars, essentially bankrupting the city on the eve of the Great Depression

A century ago, the first visitors to Philadelphia’s Sesquicentennial International Exposition—held to mark the 150th anniversary of the United States’ founding—waded through mud and wandered along unpaved sidewalks to reach the heart of the fairgrounds, only to find carpenters still at work on half-finished exhibition halls and gaping holes marking the spots where attractions had yet to be built.

Dining and shopping options were limited, and some of the few exhibits on view stretched the very definition of “entertainment.” One was a model Post Office where “you could go send yourself a letter and watch it get canceled,” says historian Thomas H. Keels, author of Sesqui! Greed, Graft and the Forgotten World’s Fair of 1926. “That was it.”

The 200,000-plus Shriners in town for their fraternal organization’s national convention realized that their parades and rallies were the main events planned for these early days of the fair. Many went home disappointed, telling family and friends that the exposition wasn’t worth visiting.

“The show is still in a state of undress, not ready at all to answer the doorbell,” a California newspaper reported. Speaking with Philadelphia’s Bulletin, an Iowa man likened the fair to a birthday dinner held by an acquaintance back home. “He got so darned excited about how many he was going to have, invitations, his speech of welcome and the program of entertainment,” the tourist recalled, “he plumb forgot to order any grub. … But the fellow had a sense of humor. ‘Come around next birthday and we’ll have something to eat,’ said he. Maybe I will.”

Held in Philadelphia between May 31 and December 31, 1926, the fair—referred to as the Sesqui—celebrated the 150th anniversary of the United States’ founding. Little remembered today, the event was a financial failure that Variety deemed “America’s greatest flop.” Exact figures are hard to come by, but Keels suggests that the fair lost the equivalent of more than $410 million in today’s dollars, effectively bankrupting the city of Philadelphia.

The exposition was America’s main celebration of the sesquicentennial. Congress authorized the fair and provided limited funding for it, in addition to issuing commemorative coins and encouraging local celebrations, but the scale of federal participation paled in comparison with that of the 1976 bicentennial and this year’s 250th anniversary of the signing of the Declaration of Independence.

Attendance at the Sesquicentennial Exposition also failed to match the numbers of Philadelphia’s 1876 centennial celebration, which attracted roughly 20 percent of the country’s population in an era when planes, cars and luxury liners had yet to make long-distance travel more accessible. Organizers predicted that 30 million people would visit the 1926 fair; ultimately, fewer than five million paid to attend.

Quick facts: American world’s fairs by the numbers

• More than 44 million people visited the “World of Tomorrow” at the 1939-40 New York World’s Fair. Two and a half decades later, 51 million visitors flocked to the 1964-65 New York World’s Fair.
• At the other end of the spectrum, the 1907 Jamestown Tercentennial Exposition drew fewer than three million visitors, making it “the most sparsely attended American world’s fair of the 20th century,” Keels writes in Sesqui.

What doomed the sesquicentennial? Poor planning and lukewarm reviews by the fair’s early visitors contributed to the disastrous outcome. So, too, did the streak of bad weather that plagued Philadelphia during the exposition’s run, with rain falling on more than half of the days the fair was open to the public.

Although some observers considered the lackluster public response a sign that the golden age of world’s fairs had come to an end, Chicago’s 1933-34 Century of Progress Exposition proved this prediction wrong, drawing more visitors than any of its predecessors. Overall, Keels attributes the 1926 fair’s failure to its “association with what was being viewed as an increasingly corrupt political machine,” headed by Pennsylvania Republican William Scott Vare.

After the fair incurred “nationwide ridicule,” Keels tells Smithsonian magazine, Vare and other local politicians were eager to move on from the endeavor, selling off leftover structures piecemeal “for pennies on the hundreds of dollars.” This push to forget the sesquicentennial has reverberated into the present: Just one building constructed for the 1926 fair stands in Philadelphia today.

“When I started to write my book,” Keels says, “I was looking for sources, and I would ask people who were very knowledgeable historians, and the immediate response was, ‘Oh yeah, the centennial, Memorial Hall in Fairmount Park.’ And it’s like, ‘No, the other one.’” They’d ask, “‘What other one?’”
