Douglas C. Engelbart was an American computer scientist whose research laid the foundation for the modern personal computer. He invented the first general-purpose computer with a graphical user interface, the precursor to the modern personal computer. Engelbart's work on what became known as the "mouse" is widely credited with being one of the most important technical advances ever made in the field of human-computer interaction
On June 8, 1968, at Stanford Research Institute's (SRI) campus in Menlo Park, California, he demonstrated a version of his ideas at a series of public sessions that were later called The Mother of All Demos.
