More than a year after celebrating Berwyn’s 100th birthday, organizers are officially concluding the city’s centennial celebration with a time capsule burial.

Timed to coincide with the nation’s birthday, Centennial Committee members will host the burial ceremony on July 4. The capsule will include mementos gathered as part of the centennial celebration such as posters, license plates, shirts and scarves. It will also include several historical books documenting Berwyn’s first 100 years, according to committee members Tammy Clausen and Carl Reina.

“The whole idea was that we would create something they could open up in the future whenever they deem fit,” Clausen said. “And we wanted to close up the centennial celebration with this ceremony.”

The library, historical society and Morton West High School also joined forces to produce a history video project. All five of Berwyn’s former living mayors — Thomas Hett, John Naughton, Joseph J. Lanzillotti, Thomas G. Shaughnessy and Michael O’Connor — participated in the project and provide, in their own words, the history of their administrations.

“I’m really proud of how it turned out,” Clausen said. “It’s really a nice little project.”

Future residents who open the capsule will be greeted with a brief history of Berwyn and the city’s centennial celebration, including a DVD documenting the weeklong centennial festival last June.

“Hopefully, they’ll be able to read DVDs by then,” Clausen joked.

This is the second time capsule Berwyn has buried. It will join the capsule buried outside the Berwyn Recreation Department 6501 W. 31st St., to commemorate the city’s 75th anniversary.

Like the time capsule at the recreation center, organizers have opted against including a date for when a future generation should open the centennial capsule. Instead, the committee is leaving all documentation of the capsule with the Berwyn Historical Society for future Berwynites to decide when they want to open it.

“Any time anybody wanted to take a look at what we buried they can,” Reina said. “I would suspect no one will unearth it for at least 100 years.”
