Douglas Engelbart

Dr. Douglas C. Engelbart (born January 30 , 1925 in Oregon ) is an American Inventor of Norwegian Descent . He is best known for inventing the Computer Mouse (in a joint effort with Bill English ); as a pioneer of Human-computer Interaction whose team developed Hypertext , networked computers, and precursors to GUIs ; and as a committed and vocal proponent of the development and use of Computers and Networks to help cope with the world's increasingly more urgent and complex problems (which Horst W. J. Rittel and others since have called Wicked Problems ).

EDUCATION

Engelbart received a from UC Berkeley in EECS in 1955. While at Oregon State, he was a member of Sigma Phi Epsilon social fraternity.

As a , now headquartered in Menlo Park , while the organization was still affiliated with Stanford University .

CAREER AND ACCOMPLISHMENTS

Historian of science Thierry Bardini has persuasively argued that Engelbart's complex personal Philosophy (which drove all his research endeavors) foreshadowed the modern application of the concept of Coevolution to the philosophy and use of Technology . Bardini points out that Engelbart was strongly influenced by the Principle Of Linguistic Relativity developed by Benjamin Lee Whorf .

Where Whorf reasoned that the sophistication of a language controls the sophistication of the thoughts that can be expressed by a speaker of that language, Engelbart reasoned that the state of our current technology controls our ability to manipulate information, and that fact in turn will control our ability to develop new, improved technologies. He thus set himself to the revolutionary task of developing computer-based technologies for manipulating information directly, and also to improve individual and group processes for knowledge-work. Engelbart's philosophy and research agenda is most clearly and directly expressed in the 1962 research report which Engelbart refers to as his 'bible': Augmenting Human Intellect: A Conceptual Framework . The concept of network augmented intelligence is attributed to Engelbart based on this pioneering work.

At SRI, Engelbart was the primary force behind the design and development of the On-Line System , or NLS. He and his team at the Augmentation Research Center (the lab he founded) developed computer-interface elements such as bit-mapped screens, multiple windows, groupware, Hypertext and precursors to the Graphical User Interface . He conceived and developed many of his user interface ideas back in the mid-1960s, long before the personal computer revolution, at a time when most individuals were kept away from computers, and could only use computers through intermediaries (see Batch Processing ), and when software tended to be written for vertical applications in proprietary systems.

Plus's Mouse, 1986]]

In 1970 Engelbart received a Patent for the wooden shell with two metal wheels ( Computer Mouse ), describing it in the patent application as an ''"X-Y position indicator for a display system"''. Engelbart later revealed that it was nicknamed the "mouse" because the tail came out the end. His group also called the on-screen cursor a "bug," but this term was not widely adopted.

He never received any Royalties for his mouse invention, partly because his patent expired in 1987, before the personal computer revolution made the mouse an indispensable input device, and also because subsequent mice used different mechanisms that did not infringe upon the original patent. During an interview, he says " SRI patented the mouse, but they really had no idea of its value. Some years later I learned that they had licensed it to Apple for something like $40,000."

Engelbart showcased many of his and ARC's inventions in 1968 at the so-called Mother Of All Demos .

ARPANET

Because Engelbart's research and tool-development for online collaboration and interactive human-computer interfaces was partially funded by ARPA , SRI's ARC became involved with the, ARPANET (the precursor of the Internet ).

On October 29 , 1969 , the world's first electronic computer network, the ARPANET , was established between nodes at Leonard Kleinrock 's lab at UCLA and Engelbart's lab at SRI. Interface Message Processors at both sites served as the Backbone of the first Internet {Link without Title} .

In addition to SRI and UCLA, UCSB , and the University Of Utah were part of the original four network nodes. By December 5 , 1969 , the entire 4-node network was connected.

ARC soon became the first Network Information Center and thus managed the directory for connections among all ARPANET nodes. ARC also published a large percentage of the early Request For Comment s, an ongoing series of publications that document the evolution of ARPANET/Internet.

END OF CORPORATE CAREER AND SUBSEQUENT DEVELOPMENTS

Engelbart slipped into relative obscurity after 1976 due to various misfortunes and misunderstandings. Several of Engelbart's best researchers became alienated from him and left his organization for Xerox PARC , in part due to frustration, and in part due to differing views of the future of computing, where Engelbart saw the future in timeshare (client/server) computing, which younger programmers rejected in favor of the personal computer. The conflict was both technical and social: Engelbart came from a time in which only timeshare computing was achievable, and also believed in joint effort; the younger programmers came from an era where centralized power was highly suspect, and personal computing was just barely on the horizon.

In his book about Engelbart, Bardini points out that in the early 1970s, several key ARC personnel were briefly involved in Est . Although est seemed like a good idea at first, it would ultimately destroy the morale and social cohesion of the ARC community.

The Mansfield Amendment , the end of the Vietnam War , and the end of Project Apollo reduced ARC's funding from ARPA and NASA . SRI's management, which disapproved of Engelbart's approach to running the center, placed the remains of ARC under the control of Artificial Intelligence researcher Bert Raphael , who fired Engelbart (from the lab that Engelbart had founded) in 1976. Engelbart's house in Atherton burned down shortly afterwards, causing him and his family even further problems.

In 1978, a company called Tymshare bought NLS , hired its creator as a Senior Scientist, and offered commercial services based upon NLS. Tymshare was already somewhat familiar with NLS; back when ARC was still operational, it had experimented with its own local copy of the NLS software on a minicomputer called OFFICE-1, as part of a joint project with ARC.

At Tymshare, Engelbart soon found himself marginalized and relegated to obscurity--operational concerns at Tymshare overrode Engelbart's desire to do further research. Various executives first at Tymshare and later at McDonnell Douglas (which took over Tymshare in 1982) expressed interest in his ideas, but never committed the funds or the people to further develop them. He left McDonnell in 1986 and retired from corporate life.

Since the late 1980s, prominent individuals and organizations have recognized the seminal importance of Engelbart's contributions:

In December 1995, at the Fourth WWW Conference in Boston, he was the first recipient of what would later become the 's Lovelace Medal . 2005 saw Engelbart made a Fellow of the Computer History Museum and winner of the Norbert Wiener Award , awarded annually by Computer Professionals For Social Responsibility .
