American Computer Museum, Computer museum in Bozeman, US.

The American Computer Museum in Bozeman displays thousands of objects tracing the development of computing technology from ancient cuneiform tablets to modern machines. The collection spans devices from different eras and demonstrates how technology transformed over time.

George and Barbara Keremedjiev founded the museum as a non-profit in May 1990 in Bozeman; it is likely the oldest extant museum devoted to computing history. George died in November 2018, and Barbara, the board and the executive director continue his goal to collect, preserve, interpret and display information-age artifacts.

Since 1997 the museum has presented the Stibitz-Wilson awards with support from Montana State University. The George R. Stibitz award honours the engineer who built the first electric binary adding unit in 1937; the Edward O. Wilson award is named for the Harvard emeritus professor. A Lifetime Achievement category was added in 2011.

The museum occupies a single building in Bozeman, with exhibits arranged in themed sections that move from ancient writing systems through mainframes to robotics and artificial intelligence. Allow time to read the labels, since the collection spans more than 4,000 years. The Vintage Mac Museum is a temporary special exhibit, so check before travelling if it is your main reason for visiting.

The collection holds an Apollo Guidance Computer and the last surviving mainframe from the Apollo 11 mission that took humans to the moon. These machines demonstrate the computing power that astronauts relied on to reach another celestial body.
