Douglas Carl Engelbart (1925-2013) was an American engineer, inventor, and computing pioneer whose work laid the foundations for modern personal computing and [[Human-Computer Interaction (HCI)]]. He invented the computer mouse, pioneered [[Hypertext]], windowed interfaces, and collaborative computing. His legendary 1968 demonstration—"The Mother of All Demos"—showcased video conferencing, word processing, hyperlinks, and real-time collaboration decades before they became mainstream. Engelbart received the Turing Award (1997) and National Medal of Technology (2000).
Engelbart's driving vision was "augmenting human intellect"—using computers to enhance humanity's ability to solve complex problems collectively. At Stanford Research Institute (SRI), he led the Augmentation Research Center (ARC) which developed the oN-Line System (NLS). Unlike contemporaries focused on artificial intelligence, Engelbart believed in amplifying human capabilities rather than replacing them. His framework of "bootstrapping" (organizations improving their own improvement process) and collective intelligence anticipated modern knowledge management. Many SRI team members, including Alan Kay, later shaped personal computing at Xerox PARC and Apple.

## Bootstrapping Framework
```
Capability Infrastructure:
┌─────────────────────────────────────────────────────────────┐
│ C ACTIVITIES │
│ (Improving the improvement process) │
│ ↓ │
│ B ACTIVITIES │
│ (Improving how we do A) │
│ ↓ │
│ A ACTIVITIES │
│ (Primary work output) │
└─────────────────────────────────────────────────────────────┘
Key insight: Organizations that invest in C activities
(improving their improvement process) accelerate faster
