The Heinz Nixdorf MuseumsForum is one of the world's largest computer museums, located at the site of the former Nixdorf Computer AG headquarters. It traces the history of computing and information technology from cuneiform tablets through the mainframe era to the personal computer — a remarkably coherent narrative covering five thousand years.
Nixdorf Computer AG was one of the most important European computer companies of the 1960s and 70s, founded by Heinz Nixdorf in Paderborn and once a rival to IBM in certain market segments. The museum's collection includes over 2,000 objects, many of them working machines that visitors can operate. For anyone interested in the history of computing, this is an essential stop — it has no real equivalent in Germany.
