Street address(es) and GPS coordinates in decimal form of the intended milestone plaque site(s):

Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. The plaque should be mounted directly in the public lobby of the museum itself.

Are the original buildings extant?

Yes, the building is former Headquarter of the German computer company Nixdorf Computer AG

Details of the plaque mounting:

On the wall in the public lobby

How is the site protected/secured, and in what ways is it accessible to the public?

The plaque will be secured by wall mount. The lobby is a public area which can be entered free of charge. The building is secure.

Who is the present owner of the site(s)?

HNF Heinz Nixdorf MuseumsForum GmbH

What is the historical significance of the work (its technological, scientific, or social importance)? If personal names are included in citation, include justification here. (see section 6 of Milestone Guidelines)

The Heinz Nixdorf MuseumsForum (HNF) is one of the largest computer museums in the world. Every year over 100.000 visitors come to Paderborn to learn about the history of computers in the permanent exhibition that spans 6.000 m² (around 65.000 ft²) and contains 2.500 objects.

The museum is located in a building that has a historic significance itself: The former headquarter of the “Nixdorf Computer AG” (NCAG), which once was one of the largest computer companies in Europe. The initial collection was donated by Heinz Nixdorf, who was convinced that computers were a tool for mankind to build a better future. He therefore envisioned the museum as a place for a broad public to learn about the history of this technology.

In addition to the permanent exhibition, the museum also has a complete floor for special exhibitions that focus on different topics like “Hello Universe! The experience of space travel” (2020), “Digging Deep - Hidden treasures from the museum’s warehouse” (2018), “IT began with Ada. Women in computer history” (2015), “Codes and Clowns. Claude Shannon - Juggler of science” (2009 – 2010), “Computer.Sport” (2009), “Computer.Medicine” (2006 - 2007) or “Computer.brain” (2001 – 2002).

The actual exhibition is only one of the many ways that the museum teaches its visitors about computers. It is called “MuseumsForum” because the building also has 7 seminar rooms and a large auditorium (386 seats) in which a wide variety of events and conferences take place. The museum is supposed to be a place where people learn and discuss historic and contemporary technologies, their potentials and risks for society. From the opening of the museum in 1996 until the end of 2020 the museum hosted 20.980 events in total. For children and pupils, the museum offers a wide range of courses and regularly hosts science competitions.

Apart from the educational aspect, the mission of the museum is also to retrieve and preserve the knowledge of how historic computers worked and how they were used. To this end, the museum follows a strategy that combines a large archive (300 m², 3200 ft²), a library with 14.000 books, reconstruction projects and the collection of oral histories.

In the community there is an ongoing discussion to what extent old computers should be kept operational or whether they should be sealed away for preservation. The HNF tries to balance the different aspects of conservation and takes an active part in the discussion with partners worldwide. For the reconstruction of an ENIAC accumulator panel the museum won the 2016 Tony Sale Award. It is currently working on a functional replica of Claude Shannon's mouse in a maze machine (“Thesus”) and a tube based replica of Heinz Nixdorf’s first electronic accumulator (“Elektronensaldierer”).

What obstacles (technical, political, geographic) needed to be overcome?

From the first idea of a computer museum in 1977 it took 19 years until the museum was finally opened. After the death of Heinz Nixdorf in 1986 the future of the project was uncertain. Thanks to the continued effort of Willi Lenz and the Nixdorf foundation the decision to establish a computer museum in Paderborn was taken in 1990.

The Berlin architects (AGM) and a scientific and technical working group in Paderborn started intensive work on the concept as of mid-1993 under the lead of managing director Norbert Ryska. A total of 100 experts from around the world were involved in the consultations, while work on the envisaged topics was entrusted to twelve local scientists. Meanwhile, a dozen interior designers, designers and multimedia programmers are involved in the project at AGM in Berlin. Simultaneous work on 60 exhibition areas called for ongoing complex coordination and planning between scientists, designers, technicians and structural engineers.

On 24 October 1996, the HNF was officially opened by Federal Chancellor Helmut Kohl.

What features set this work apart from similar achievements?

The museum in its size and broad engagement in computer history is a unique place that attracts visitors and historians from around the world. It does not only focus on the exhibition of historic artifacts, but plays an active role as it organized two international conferences on history of computing in 1998 and 2000:


- Hashagen, Ulf; Keil-Slawik, Reinhard; Norberg, Arthur L. (Eds.): History of Computing: Software Issues. Berlin, Heidelberg, New York: Springer 2002

The museum is also in close contact with other museums in Germany and worldwide and has fruitful collaborations and exchanges of ideas. One example of such a collaboration are the “Cypher Events” that were conducted between the HNF and the british National Museum of Computing (TNMoC) in Bletchley Park. During the first event in 2007, a secret message was encrypted using an original Lorenz SZ42 machine from WWII and sent from Paderborn to Bletchley Park using Morse code. There, the encrypted message was fed to the Colossus rebuild which then cracked the code. This event was repeated 10 years later, but this time the message was encrypted using an Enigma and decrypted using the Turing-Welchman Bombe (
