Worldwide, there are probably only four copies: the inventor of The first Computer mouse, Rainer Mallebrein, one of the extremely rare equipment donated to the Museum.

“This is the Ur-mouse. We were ahead of our time. We have developed between 1965 and 1968, when there were no Personal computers, not even the word PC”, described the 85-Year-old on Tuesday in Paderborn. The engineer out of the room, Constance, presented the exhibit as a permanent loan to the Heinz Nixdorf Museum forum (HNF), that claims to be the world’s largest computer Museum.

Mallebrein had designed the mouse for Telefunken, the company sold from 1968, along with his former top computer TR 440. However, only 46 Times, especially in universities, the computer was up to 20 million Mark practically prohibitively expensive, says Mallebrein. His mouse to have for the 1500 Mark, fell into oblivion.

A Patent it is not already there. “Due to low level of invention”, then in the Letter from the patent office, the Senior. “About possibilities of application was at the time, had not been spoken, – namely, that the mouse-human-machine-can drive interaction.” Telefunken cared not large. Sponge over it. Mallebrein then devoted himself to other inventions.

The worldwide success of the computer mouse began only in the 1980s. On the Basis of the Mallebrein system, such as the 85-Year-old and the HNF stress. And the development of the American mouse-father, Douglas Engelbart is considered to be Central. At the end of 1968 – two months after the presentation of the German invention – presented by Engelbart in the United States also has a PC mouse. Not with a roller equipped, but with two wheels. This mouse was celebrated, the German mouse remained a grey. You have known in San Francisco and constancy nothing of each other, says Mallebrein.

angel’s invention got the catchy name “mouse”. And as the German inventors called their child? “We got embarrassed there. We were far too sober and shy and the Whole “trackball control called”.” Well. Still, His device made in Germany was the American development of “constructive far superior”, Mallebrein convinced. Today, there is still a copy in Stuttgart and Munich, also know of another in the United States. The wars.

The breakthrough for the computer mouse came with the first reasonably affordable computers from Apple, which had a surface a graphical user: Lisa (1983) and Macintosh (1984). Apple co-founder Steve Jobs had previously seen the legendary California research center, Xerox PARC, as one can control with a mouse to a computer.

the fourth Mallebrein mouse has the way to him, and now to the Museum was also a history: He had found ten years ago on a report on the invention in a Telefunken magazine from October 1968, tells art historian Ralf Bülow. He made the public, there were reports in the media. An Ex-colleague had congratulated him on the “mouse-breakthrough”, and later a nail tracked down a new copy, says Mallebrein. This is now on display permanently behind glass in Paderborn, Germany.
