Inventor of the mouse dies

Douglas C. Engelbart, the technologist who first conceived the computer mouse and laid out a vision of the internet decades before others brought those ideas to the mass market, has died. At a one hour-long event in 1968 he unveiled both the first mouse and then held the first videoconference with a colleague who was 30 miles away. He never received any royalties for the mouse, which SRI patented and later licensed to Apple.
