  1. Intro to CS Schroeder Joel Smith Douglas Engelbart

  2. Early Years • Douglas Engelbart was born in 1925, and grew up on a small farm in Oregon. • He attended Oregon State University to study electrical engineering in 1942. • Douglas then participated in WWII as a naval radio technician in the Philippines. • After the war, he proceeded to enroll in the graduate program for electrical engineering at UC Berkeley and earned his Ph.D. in 1955.

  3. Early Career • While attending Berkeley he participated in the construction of CALDIC. • CALDIC stood for California Digital Computer. • It was a research project headed by the Office of Naval Research in Berkeley to develop a more efficient computer. • After Berkeley, he started a company called Digital Techniques which quickly failed. • Engelbart was then hired by Magnetic Logic Devices at the Stanford Research Institute (SRI) to work on logic circuits.

  4. Online System • In the 1960s, Engelbart began working with the Augmentation Research Center (ARC) at the Stanford Research Institute to create the NLS aka Online System. • The NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts. • Because Engelbart's research and tool-development for online collaboration and interactive human-computer interfaces was partially funded by ARPA (Advance Research Project Agency), SRI's ARC became involved with the ARPANET (the precursor of the Internet).

  5. ARPANET • On October 29, 1969, the ARPANET, the world's first electronic computer network 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. • 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.

  6. The mouse • In 1967, Engelbart applied for, and in 1970 he received a patent for a wooden shell with two metal wheels. • He describe his patent as an "X-Y position indicator for a display system". • Engelbart later said that it was nicknamed a "mouse" because the cord that came out of the back looked like a tail. • His group also called the on-screen cursor a "bug," but this term was not widely adopted.

  7. The Mouse • He never received any royalties for his mouse invention. • This was because his patent expired in 1987, which was before the PC revolution made the mouse an important utility. • Also newer mice used different mechanisms that did not infringe upon the original patent. • During an interview, he said "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."

  8. Open Source HyperScope Project • In the year 2005, Engelbart received a National Science Foundation grant to help fund the open source HyperScope project. • The Hyperscope project has built a browser component using Ajax and DHTML designed to augment multiple viewing and jumping capabilities (linking within and across various documents). • Hyperscope is the next attempt of Engelbarts to create a stronger and more reliable online system.

  9. The Bootstrap Institute • Currently at the age of 81, he is also the director of his own company, the Bootstrap Institute which he founded in 1988 with his daughter, Christina Engelbart. • It is located in Fremont, California and promotes Engelbart's latest refinement of his philosophy, the concept of Collective IQ, and development of the Open Hyper-Document Systems(OHS). • Bootstrap is housed rent-free courtesy of the Logitech Corp., the world's largest manufacturer of computer mice.
