William English, the co-inventor of the computer mouse, passes away at 91

William Kirk English, the American computer engineer who co-invented the world’s first computer mouse, has passed away. He was 91 years old.
In 1964, he was the first person to co-develop the mouse along with Douglas Engelbart, at the Stanford Research Institute and ‘demonstrated it in 1968, in what was dubbed ‘the mother of all demos.’
The original mouse, as built by Bill English in the mid-60s, was merely a pinewood block, a crude button, and a connector.
