[Leica] Mouse (Computer History Museum)

[kanner at acm.org (Herbert Kanner)]

In 1963, Doug Engelbart invented the mouse as a fundamental part of a 
computer system that he was developing. What is displayed is a replica of 
his original version. It had two sharp-edged wheels whose axes were at right 
angles to each other. If you look large, you can see one of those wheels on 
the left.

In 1969, Doug gave a demonstration of his system at a conference in San 
Francisco. I was there! He captivated his audience, moving documents around 
on the screen and demonstrating hyperlinks from one document to another. It 
became known as "The mother of all demonstrations," largely because nothing 
crashed. Doug was in his laboratory at Stanford Research Institute in Menlo 
Park, CA, about forty miles from San Francisco. The television signal was 
microwaved to a van on Skyline Drive, a road 2000 feet up on a mountain 
ridge between him and the Pacific Ocean. The van then relayed the signal to 
the auditorium in San Francisco.
