“What IS that?” is a question often asked by visitors, volunteers and even staff of the Butler County Historical Society. A new exhibit in the Benninghofen Museum, “Intriguing Objects and Curiosities,” invites visitors to use their knowledge of history to identify artifacts from the Society’s basement, closets and back shelves. Categories in the exhibit include personal hygiene, clothing and accessories, medical devices, hobbies, toys, needlework, household items and more. Even easily identified objects provide a fascinating glimpse of life at an earlier time. The exhibit is available for viewing until April 30th.

Upcoming Event
The Disappearance of Ron Tammen: A Deep Dive into Buried Clues, Silent Bystanders, and the Latest Evidence of What Really Happened”
Saturday, April 26: 1:00 pm & 3:30 pm
“The Disappearance of Ron Tammen: A Deep Dive into Buried Clues, Silent Bystanders, and the Latest Evidence of What Really Happened”
On April 19, 1953, Ronald Tammen disappeared from Miami University, and ever since that day, anyone who’s heard his story has been justifiably baffled. How could a smart, responsible, 19-year-old business major wander off campus without anyone noticing? What’s more, how has he never turned up in the ensuing years? According to Jennifer Wenger, who has been researching Ron’s case for the past 15 years, the mystery is more intricately layered than we could have imagined. Wenger will be discussing clues that were withheld from the public, people who knew more than they were letting on, and, most intriguing of all, a decades-old secret that the FBI has been keeping about Ron that could be a gamechanger in finding the answer to how and why he disappeared.
