BRODHEAD, Wisconsin — The Wisconsin Aviation Hall of Fame unveiled its Leo J. Kohn Collection exhibit at the Kelch Aviation Museum June 9, 2024.
The exhibit showcases the photography of Leo J. Kohn, whose work has captured the essence of aviation from the early 20th century, according to museum officials.
The collection includes photographs of both rare and common aircraft, civilian and military, experimentals, and one-of-a-kinds, plus candid moments that highlight Kohn’s dedication and passion for documenting aviation history.
The event featured speeches by Leo’s son, Bill Kohn, and daughter, Mary Ellen Kohn-Buday, who shared anecdotes about their father’s legacy, and emphasized the meticulous efforts that the Wisconsin Aviation Hall of Fame (WAHF) is putting into the preservation and digitization of the collection.

“The Leo J. Kohn Collection is more than just a compilation of photographs,” said WAHF President Kurt Stanich, a key organizer of the exhibit. “It’s a testament to the rich history of aviation and the individuals who have contributed to its development.
“The Wisconsin Aviation Hall of Fame is honored to share this incredible collection with the public and ensure that Leo’s legacy continues to inspire future aviators and historians,” he continued. “Through several generous donors we have now reached 47% of the funds needed to digitize this tremendous collection of more than 30,000 historic aircraft negatives.”
The unveiling ceremony was held in conjunction with the ribbon-cutting of the museum’s new Wagner Welcome Atrium. The Wagner Foundation’s Bobbie Wagner was on hand to help cut the ribbon on the atrium, which will serve as a central hub for museum visitors, according to officials.
Bobbie Wagner was a co-founder of Wag-Aero, along with her husband Dick Wagner, who passed away in 2012. They were jointly inducted into the Wisconsin Aviation Hall of Fame in 2008.
