Engelbart’s work is the very foundation of personal computing and the Internet. His vision was to solve humanity's most important problems by using computers to improve communication and collaboration. He was world famous for his invention of the computer mouse and the origins of interactive computing.
Transforming the way we understand computers and interact with technology, the mouse is regarded as one of the greatest innovations of the twenty-first century. The point and click system remains largely unchanged since its inception, and over one billion mice have been sold since it was made commercially available in 1984.
Among his many accolades, Engelbart received the National Medal of Technology in 2000, the Lemelson-MIT Prize in 1997, and the Turing Award, also in 1997.
