William English, Who Helped Construct the Laptop Mouse, Dies at 91

William English, the engineer and researcher who helped construct the primary laptop mouse and, in 1968, orchestrated an elaborate demonstration of the know-how that foretold the computer systems, tablets and smartphones of as we speak, died on July 26 in San Rafael, Calif. He was 91.

His demise, at a medical facility, was confirmed by his spouse, Roberta English, who mentioned the trigger was respiratory failure.

Within the late Nineteen Fifties, after leaving a profession within the Navy, Mr. English joined a Northern California analysis lab referred to as the Stanford Analysis Institute, or S.R.I. (now referred to as SRI Worldwide). There he met Douglas Engelbart, a fellow engineer who hoped to construct a brand new sort of laptop.

At a time when solely specialists used computer systems, getting into and retrieving info via punched playing cards, typewriters and printouts, Mr. Engelbart envisioned a machine that anybody may use just by manipulating photographs on a display screen. It was an idea that may come to outline the knowledge age, however by his personal admission Mr. Engelbart had struggled to clarify his imaginative and prescient to others.

Mr. English, identified to everybody as Invoice, was one of many few who understood these concepts and who had the engineering expertise, endurance and social expertise wanted to appreciate them. “He was the man who made every thing occur,” mentioned Invoice Duvall, who labored alongside Mr. English throughout these years. “When you informed him one thing wanted to be completed, he found out how you can do it.”

Amongst different issues, Mr. Engelbart, who died in 2013 at 88, envisioned a mechanical gadget that would transfer a cursor throughout a display screen and carry out discrete duties by deciding on explicit symbols or photographs. Mr. English made this a actuality, constructing the primary laptop mouse and, via a sequence of exams, exhibiting that it may navigate a display screen quicker than some other gadget developed at S.R.I.

Their multifaceted experimental laptop was referred to as oNLine System, or NLS, and on Dec. 9, 1968, they unveiled it at an occasion in San Francisco that turned referred to as “The Mom of All Demos.”

As Mr. Engelbart demonstrated the machine onstage on the Civic Auditorium, a reside video appeared on the wall behind him exhibiting the seamless interplay between his mouse and the pc display screen. Mr. English directed this elaborate manufacturing from the again of the auditorium, counting on cameras and microphones each there and on the lab that housed the pc in Menlo Park, Calif., greater than 30 miles away.

This Mom of All Demos — exhibiting early types of on-line textual content enhancing, video conferencing and “hypertext,” the hyperlinks now used to navigate net pages on the web — presaged not solely the desktop and laptop computer computer systems that rose to the fore within the Eighties and ’90s, but in addition the smartphones and tablets that may come to suffuse on a regular basis life.

“It confirmed what a pc interface may — and will — appear like,” mentioned Doug Fairbairn, a director of the Laptop Historical past Museum in Mountain View, Calif. He labored alongside Mr. English and plenty of different computing pioneers within the Nineteen Seventies.

William Kirk English was born on Jan. 27, 1929, in Lexington, Ky., the one son of Harry and Caroline (Grey) English. His father was {an electrical} engineer who managed coal mines in japanese Kentucky and West Virginia; his mom was a homemaker. His father had two different sons, John and Robert, from a earlier marriage.

Within the early Nineteen Forties, after the outbreak of the Second World Battle, Mr. English left for Arizona to attend a boarding college — what was referred to as a “ranch college,” the place he discovered to trip horses as effectively — close to Tucson. After returning dwelling, he studied electrical engineering on the College of Kentucky.

His time within the Navy included postings in Northern California and Japan. He then took his analysis place on the Stanford Analysis Institute, at first engaged on a brand new sort of laptop reminiscence — a rotating steel drum the dimensions of a desk that would retailer as many as three pages of textual content — earlier than embracing the mission that turned NLS.

After Mr. Engelbart had envisaged the pc mouse and drawn a tough sketch of it on a notepad, Mr. English constructed it within the mid-Nineteen Sixties. Housed inside a small pinewood case, the gadget consisted of two electrical mechanisms, referred to as potentiometers, that tracked the motion of two small wheels as they moved throughout a desktop. They referred to as it a mouse due to the way in which the pc’s on-screen cursor, referred to as a CAT, appeared to chase the gadget’s path.

As they had been creating the system, each Mr. English and Mr. Engelbart had been a part of the government-funded L.S.D. exams performed by a close-by lab referred to as the Worldwide Basis of Superior Examine. Each took the psychedelic as a part of a sweeping effort to find out whether or not it may “open the thoughts” and foster creativity.

Although Mr. Engelbart oversaw the NLS mission, the 1968 demonstration in San Francisco was led by Mr. English, who introduced each engineering and theater expertise to the duty. Within the mid-Nineteen Fifties he had volunteered as a stage supervisor for a Bay Space theater troupe referred to as The Actor’s Workshop.

For the San Francisco occasion, he used a video projector the dimensions of a Volkswagen Beetle (borrowed it from a close-by NASA lab) to rearrange and mission the reside photographs behind Mr. Engelbart as he demonstrated NLS from the stage. He had been in a position to arrange the wi-fi hyperlink that despatched video between the Menlo Park laptop lab and the auditorium after befriending a phone firm technician.

Three years after the demonstration, Mr. English left S.R.I. and joined a brand new Xerox lab referred to as the Palo Alto Analysis Middle, or PARC. There he helped adapt lots of the NLS concepts for a brand new machine referred to as the Alto, which turned a template for the Apple Macintosh, the primary Microsoft Home windows private computer systems and different internet-connected units.

“The entire goal was to implement the concepts behind NLS” throughout a community of private computer systems, mentioned Alan Kay, a key researcher behind the Alto.

Mr. English’s first marriage, to Patricia Dickson, resulted in divorce. He had met his future second spouse, Roberta Mercer, whereas they had been each working at S.R.I. Along with her, he’s survived by two sons from his first marriage, Aaron and John; a stepdaughter, Patricia; and a granddaughter.

This week, when requested if he remembered that Mr. English had organized the wi-fi video feed for the Mom of All Demos via an opportunity assembly with a phone technician in Silicon Valley, Mr. Kay mentioned he didn’t.

“However it doesn’t shock me,” he added. “That seems like Invoice.”
