Douglas Engelbart

The mouse and interactive computing. At the Stanford Research Institute Engelbart's team built the oN-Line System, and in a 1968 San Francisco demonstration he showed a mouse, windows of text, hypertext links, shared editing and video calls, all at once. He conceived the mouse and holds its patent; Bill English built it. Few of his systems sold, but the people he influenced built the personal computer. He died in 2013.
