About the Mimms Museum of Technology and Art

Museum Founders

The Mimms Museum of Technology and Art was founded by Lonnie and Karin Mimms, a visionary couple united by their shared passion for innovation, education, and culture. Lonnie has spent more than 40 years building one of the most significant private collections of computing artifacts in the world, while Karin, a former educator, brings a lifelong commitment to learning and storytelling. Together, they created the museum as their legacy project—an inspiring space where the evolution of technology and the art it influences are brought to life through immersive exhibitions and compelling narratives. They aim to educate, engage, and spark curiosity across generations by showcasing the deep connections between human creativity and technological advancement.

Preserve, Educate, Empower

In the past half century, computing has grown from a few gadgets to an almost universal extension of human life. Yet while computing has become commonplace, the history of its innovation is being lost every day, as ‘old’ technology is discarded, recycled, or relinquished to the landfill.
Mimms Museum of Technology and Art, located in Roswell, GA just outside Atlanta, was created to preserve this history, and educate visitors on the past and future of computing, empowering the innovators of tomorrow.

Our History

Built from a life long passion for computers, art, and technology, Mimms Museum of Technology and Art (formerly Computer Museum of America) has grown into one of the world’s most comprehensive collections of computing artifacts—preserving the history of innovation, feats of engineering, and discovery for future generations. These artifacts of the digital era are not only beautiful but invaluable records of the journey that shaped our modern world.
Over the years, Mimms Museum has curated engaging exhibits that share these stories, while also loaning artifacts and historical items to esteemed institutions like the Smithsonian, Microsoft, Tellus Science Museum, Georgia Institute of Technology, and even movie and TV productions.
The museum started its journey through a series of pop-up exhibits staged in a repurposed CompUSA. These served as a proof of concept offering valuable visitor feedback and shaping the vision for a permanent facility.
The Apple Pop-Up chronicled Apple’s rise from garage startup to global innovator, featuring rare pieces like the first disk II controller card, Apple II, Apple Lisa, and more. The second pop-up, “LINK – The History of the PC” guided visitors through the early, unstandardized days of personal computing, with iconic machines like the IBM PC, TRS-80, and Commodore 64.
On July 20, 2019—the 50th anniversary of the first moon walk—the Computer Museum of America opened its doors to the public at its permanent location in Roswell, Georgia.
On March 6, 2025, the museum officially rebranded as the Mimms Museum of Technology and Art, a name that better captures the profound connection between the two disciplines. The announcement took place during its annual BYTE fundraiser and was accompanied by the debut of a temporary gallery showcasing more than 30 rare Salvador Dalí prints, many of them signed by the iconic surrealist.
At our core, we believe that by preserving the past, we can inspire the future.
