London: Douglas Engelbart, the man who invented the computer mouse, has died aged 88.
Engelbart developed mouse in the 1960s as a wooden shell covering two metal wheels, patenting it long before the mouse`s widespread use.
According to the BBC, he also worked on early personifications of e-mail, word processing and video teleconferences at Stanford Research Institute.
Engelbert`s daughter, Christina, notified about his death to the Computer History Museum in Mountain View, California, in an email.
She said that her father had been in poor health and died peacefully on Tuesday night in his sleep.
Engelbart was born on 30 January 1925 in Portland, Oregon, to a radio repairman father and a housewife mother, the report said.
According to the report, he did not make much money from the mouse because its patent ran out in 1987, before the device became widely used.
He is survived by his second wife, Karen O`Leary Engelbart, and four children.
