The computer mouse is familiar to everyone because it is a most useful device used by people to communicate with a desktop computer. It gave way to the touch pad（触摸板）for laptops but some people still use it for their laptops.

The man who invented the computer mouse, Douglas Engelbart died at home on July 2, 2013.Engelbart’s daughter Christina notified his death to the state’s Computer History Museum in an email. She said that her father had kidney failure and died peacefully on Tuesday night in his sleep.

Engelbart developed the mouse in the 1960s—a wooden shell covering two meal wheels, obtaining a patent for it long before the mouse’s widespread use.

Engelbart was born on January 30, 1925 in Portland, Oregon, to a radio repairman father and a housewife mother. He was working in a government aerospace laboratory in California when he had the vision of the computer mouse.

When he started working, the computer was at the infant stage and was a big machine that required huge amounts of time to process data. But Engelbart had already imagined the future of the computer and related technology. He was ahead of many scientists working on the same technology.

After the Vietnam War he started working on the interactive computer at an experimental research group at Stanford Research Institute, which had the financial backing of the Air Force, NASA and the Advanced Research Projects Agency, an arm of the Defense Department.

In 1968at a conference, he demonstrated a working model of a mouse, computer and keyboard that was used to share data on network. He demonstrated text editing, video conferencing and hypertext. His idea of computer network was the base and first step towards ARPANET.

He never made money with the invention of the mouse as his patent was till 1987 and the mouse came into wide use after the 1980s when Steve Jobs of Apple bought one button mouse. Apple never paid any money to Engelbart.
