Computer Mouse Inventor Doug Engelbart Dies

Inventor of the computer mouse Doug Engelbart has died at the age of 88.

The death of the American, who also developed early incarnations of email, word processing programs and the internet, was confirmed by the museum where he had been a fellow since 2005.
The Computer History Museum in California said it was notified in an email from his daughter, Christina. His wife, Karen O'Leary Engelbart, told the New York Times the cause of death was kidney failure.
Mr Engelbart was a pioneer of efforts to make computers user-friendly and said his work was all about "augmenting human intellect".
He developed the mouse in the 1960s and patented in 1970. At the time, it was a wooden shell covering two metal wheels, with an X-Y position indicator for a display system.
