Douglas Engelbart (1925–2013) was an American electrical engineer who spent his career on one question: how can computers make people, working together, better at solving hard problems? Long before personal computing existed, he built working answers, among them the computer mouse and a system that let people edit shared documents, link ideas, and confer over video across a network. His work treated the machine as a way to augment human intellect rather than simply automate tasks.
Douglas Carl Engelbart was born on 30 January 1925 in Portland, Oregon, and grew up on a small farm nearby during the Great Depression. He enrolled at Oregon State University to study electrical engineering, but the Second World War interrupted his studies. He served in the U.S. Navy as an electronic and radar technician in the Philippines, and it was there, in 1945, that he read Vannevar Bush's essay "As We May Think," which imagined a desk-sized machine, the "memex," for storing and linking a person's books, records, and messages (Britannica).
He completed his bachelor's degree at Oregon State in 1948, worked briefly as an engineer at the Ames Aeronautical Laboratory, then earned a master's (1953) and a PhD (1955) in electrical engineering at the University of California, Berkeley. Around 1950, newly engaged and settled in a steady job, he decided he had no clear direction, and resolved instead to devote his career to helping people cope with the world's increasingly complex and urgent problems (Doug Engelbart Institute).
In 1957 Engelbart joined the Stanford Research Institute (SRI, now SRI International) in Menlo Park, California. In 1962 he set out his program in a report prepared for the Air Force Office of Scientific Research, "Augmenting Human Intellect: A Conceptual Framework," arguing that computers should extend human reasoning and coordination, and do far more than perform calculations (Britannica). With funding from ARPA and NASA, he founded the Augmentation Research Center (ARC), where his team built the oN-Line System, or NLS.
While testing ways to point at objects on a screen, Engelbart sketched a hand-held device with two wheels; his colleague Bill English built the first prototype around 1964, a carved wooden shell that someone in the lab nicknamed the "mouse." Engelbart filed for a patent in 1967 and received U.S. Patent 3,541,541 in 1970 for an "X-Y position indicator for a display system" (Wikipedia).
On 9 December 1968, at the Fall Joint Computer Conference in San Francisco, Engelbart gave a live, roughly 90-minute demonstration of NLS that later became known as "The Mother of All Demos." Working from a terminal on stage, linked by leased lines to the computer some 30 miles away at SRI, he showed the mouse, hypertext links, on-screen windows, real-time collaborative editing of a shared document, and video conferencing with colleagues back at the lab (Computer History Museum). Much of what he presented would not reach ordinary users for another two decades.
Many of Engelbart's ideas moved to Xerox PARC in the 1970s, where several ARC researchers went, and from there into the Xerox Alto, the Apple Macintosh, and Microsoft Windows. The mouse, on-screen windows, hypertext, and shared editing are now unremarkable parts of everyday computing (ETHW). His concept of "bootstrapping," using better tools to build still better tools, and his later idea of raising a group's "Collective IQ," continued to shape his thinking.
Recognition came late. Engelbart received the ACM Turing Award in 1997, the Lemelson-MIT Prize in 1997, induction into the National Inventors Hall of Fame in 1998, and the National Medal of Technology in 2000 (Wikipedia). He kept promoting his vision through the Bootstrap Institute, later renamed the Doug Engelbart Institute, which his daughter Christina helped lead. He died of kidney failure at his home in Atherton, California, on 2 July 2013, aged 88.
Engelbart spent decades on the belief that tools should help people think and remember together. Confinity keeps his story in full, the ideas and the long wait for recognition alike, so that the person behind the everyday mouse stays legible to anyone who looks.
