Douglas C. Engelbart, 1925-2013: Computer Visionary Who Invented the Mouse

Douglas C. Engelbart was 25, just engaged to be married and thinking about his future when he had an epiphany in 1950 that would change the world.

A prototype of the first computer mouse, which was invented in 1964 by Dr. Engelbart and constructed by two of his associates.

He had a good job working at a government aerospace laboratory in California, but he wanted to do something more with his life, something of value that might last, even outlive him. Then it came to him. In a single stroke he had what might be safely called a complete vision of the information age.

The epiphany spoke to him of technology’s potential to expand human intelligence, and from it he spun out a career that indeed had lasting impact. It led to a host of inventions that became the basis for the Internet and the modern personal computer.

In later years, one of those inventions was given a warmhearted name, evoking a small, furry creature given to scurrying across flat surfaces: the computer mouse.

Dr. Engelbart died on Tuesday at 88 at his home in Atherton, Calif. His wife, Karen O’Leary Engelbart, said the cause was kidney failure.

Computing was in its infancy when Dr. Engelbart entered the field. Computers were ungainly room-size calculating machines that could be used by only one person at a time. Someone would feed them information in stacks of punched cards and then wait hours for a printout of answers. Interactive computing was a thing of the future, or in science fiction. But it was germinating in Dr. Engelbart’s restless mind.

In his epiphany, he saw himself sitting in front of a large computer screen full of different symbols — an image most likely derived from his work on radar consoles while in the Navy after World War II. The screen, he thought, would serve as a display for a workstation that would organize all the information and communications for a given project.

It was his great insight that progress in science and engineering could be greatly accelerated if researchers, working in small groups, shared computing power. He called the approach “bootstrapping” and believed it would raise what he called their “collective I.Q.”

A decade later, during the Vietnam War, he established an experimental research group at Stanford Research Institute (later renamed SRI and then SRI International). The unit, the Augmentation Research Center, known as ARC, had the financial backing of the Air Force, NASA and the Advanced Research Projects Agency, an arm of the Defense Department. Even so, in the main, computing industry professionals regarded Dr. Engelbart as a quixotic outsider.

In December 1968, however, he set the computing world on fire with a remarkable demonstration before more than a thousand of the world’s leading computer scientists at the Fall Joint Computer Conference in San Francisco, one of a series of national conferences in the computer field that had been held since the early 1950s. Dr. Engelbart was developing a raft of revolutionary interactive computer technologies and chose the conference as the proper moment to unveil them.

For the event, he sat on stage in front of a mouse, a keyboard and other controls and projected the computer display onto a 22-foot-high video screen behind him. In little more than an hour, he showed how a networked, interactive computing system would allow information to be shared rapidly among collaborating scientists. He demonstrated how a mouse, which he invented just four years earlier, could be used to control a computer. He demonstrated text editing, video conferencing, hypertext and windowing.

In contrast to the mainframes then in use, a computerized system Dr. Engelbart created, called the oNLine System, or NLS, allowed researchers to share information seamlessly and to create and retrieve documents in the form of a structured electronic library.

The conference attendees were awe-struck. In one presentation, Dr. Engelbart demonstrated the power and the potential of the computer in the information age. The technology would eventually be refined at Xerox’s Palo Alto Research Center and at the Stanford Artificial Intelligence Laboratory. Apple and Microsoft would transform it for commercial use in the 1980s and change the course of modern life.

This article has been revised to reflect the following correction:

Correction: July 3, 2013

An earlier version of this article misstated the original name of the research group SRI International. It was Stanford Research Institute, not Stanford Research International. It also misidentified one of Mr. Engelbart’s inventions. What he called “the bug” is now known as the cursor, not the mouse.

Southwest Cancels 57 Flights After Computer Glitch

Full service was restored just after 2 a.m. EDT Saturday, but the Dallas-based airline is still working to clear a backlog of flights and reposition planes and crew.

The airline — the country's largest domestic carrier — canceled 43 flights Friday night and another 14 Saturday morning.

Southwest is the latest airline to ground flights because of a large computer outage. But its problem was minor compared to those experienced by two competitors — thanks in part to its late-day timing.

In April, American Airlines grounded all of its flights nationwide for several hours due to computer problems. The airline ultimately canceled 970 flights. And last year, United Airlines had two major outages: one in August delayed 580 flights; another in November delayed 636 flights.

The problem was detected around 11 p.m. EDT Friday, Southwest spokesman Brad Hawkins said. It impaired the airline's ability to do such things as conduct check-ins, print boarding passes and monitor the weight of each aircraft. Some flights were on the taxiway and diverted back to the terminal, Hawkins said. Flights already in the air were unaffected.

Most of Southwest's cancelations Friday night were in the western half of the country, according to airline spokeswoman Michelle Agnew. Saturday's cancelations were scattered across the U.S. They included planes leavings from Minneapolis, Chicago, Phoenix, Denver and San Diego, according to flight tracking service FlightAware.

Southwest flies an average of 3,400 flights each day.

Agnew said in an email Saturday morning that the airline's technology team is "still working to confirm the source of the issue."

Shortly after 2 a.m., Southwest posted on its Twitter page that "systems are operating and we will begin work to get customers where they need to be. Thanks for your patience tonight."

Agnew said the computer system was "running at full capacity" by early Saturday. Before that, though, officials used a backup system that was much more sluggish.

New Computer Attacks Come From Iran, Officials Say

The targets have included several American oil, gas and electricity companies, which government officials have refused to identify. The goal is not espionage, they say, but sabotage. Government officials describe the attacks as probes looking for ways to seize control of critical processing systems.

Investigators began looking at the attacks several months ago, and when the Department of Homeland Security issued a vaguely worded warning this month, a government official told The New York Times that “most everything we have seen is coming from the Middle East.”

Government officials and outside experts on Friday confirmed a report in The Wall Street Journal that the source of the attacks had been narrowed to Iran. They said the evidence was not specific enough to conclude with confidence that the attacks were state-sponsored, but control over the Internet is so centralized in Iran that they said it was hard to imagine the attacks being done without government knowledge.

While the attackers have been unsuccessful to date, they have made enough progress to prompt the Homeland Security warning, which compared the latest threat to the computer virus that hit Saudi Aramco, the world’s largest oil producer, last year. After investigations, American officials concluded that the Aramco attack, and a subsequent one at RasGas, the Qatari energy company, were the work of Iran.

Taken together, officials say, the attacks suggest that Iran’s hacking skills have improved over the past 18 months. The Obama administration has been focused on Iran because the attacks have given the Iranian government a way to retaliate for tightened economic sanctions against it, and for the American and Israeli program that aimed similar attacks, using a virus known as Stuxnet, on the Natanz nuclear enrichment plant.

That effort, code-named Olympic Games, slowed Iran’s progress for months, but also prompted it to create what Iran’s Islamic Revolutionary Guards Corps calls a cyber corps to defend the country.

This week Iran denied being the source of any attacks, and said it had been a victim of American sabotage. In a letter to the editor of The Times, responding to a May 12 article that reported on the new attacks’ similarity to the Saudi Aramco episode, Alireza Miryousefi, the head of the press office of the Iranian mission to the United Nations, wrote that Iran “never engaged in such attacks against its Persian Gulf neighbors, with which Iran has maintained good neighborly relations.”

“Unfortunately, wrongful acts such as authorizing the 2010 Stuxnet attack against Iran have set a bad, and dangerous, precedent in breach of certain principles of international law,” he wrote.

American officials have not offered any technical evidence to back up their assertions of Iranian authorship of the latest attacks, but they describe the recent campaign as different from most attacks against American companies — particularly those from China — which quietly siphon off intellectual property for competitive purposes.

The new attacks, officials say, were devised to destroy data and manipulate the machinery that operates critical control systems, like oil pipelines. One official described them as “probes that suggest someone is looking at how to take control of these systems.”

The White House would not confirm that Iran was the source, but Laura Lucas, a spokeswoman for the National Security Council, said that “mitigating threats in cyberspace, whether theft of intellectual property or intrusions against our critical infrastructure” was a governmentwide initiative and that the United States would consider “all of the measures at its disposal — from diplomatic to law enforcement to economic — when determining how to protect our nation, allies, partners, and interests in cyberspace.”

In the past, government officials have privately warned companies under threat. But Homeland Security was able to issue a broader warning because of an executive order, signed in February, promoting greater information sharing about such threats between the government and private companies that oversee the nation’s critical infrastructure.

An agency called ICS-Cert, which monitors attacks on computer systems that run industrial processes, issued the warning. It said the government was “highly concerned about hostility against critical infrastructure organizations,” and included a link to a previous warning about Shamoon, the virus used in the Saudi Aramco attack last year.

That attack prompted Leon E. Panetta, then defense secretary, to warn of a “cyber-Pearl Harbor” if the United States did not take the threat seriously.

Saudi Aramco and RasGas both said that the attackers had failed in their efforts to infiltrate their oil production systems.

Government officials also say Iran was the source of a separate continuing campaign of attacks on American financial institutions that began last September and has since taken dozens of American banks intermittently offline, costing millions of dollars. But that attack was a less sophisticated “denial of service” effort.

Jeff Moss, chief security officer at the Internet Corporation for Assigned Names and Numbers, the private body that oversees the basic design of the Internet, said: “For the last year, Iran has been focused on disrupting financial institutions’ Web sites. If they are going after energy, and opening a multiprong front, at what point does it cross from annoyance to a threshold?”

Disruptions: Brain Computer Interfaces Inch Closer to Mainstream

Muse, a lightweight, wireless headband, can engage with computers, iPads and smartphones.Muse Muse, a lightweight, wireless headband, can engage with computers, iPads and smartphones.

Last week, engineers sniffing around the programming code for Google Glass found hidden examples of ways that people might interact with the wearable computers without having to say a word. Among them, a user could nod to turn the glasses on or off. A single wink might tell the glasses to take a picture.

But don’t expect these gestures to be necessary for long. Soon, we might interact with our smartphones and computers simply by using our minds. In the next couple of years, we could be turning on the lights at home just by thinking about it, or sending an e-mail from our smartphone without even pulling the device from our pocket. Further into the future, our robot assistant will appear by our side with a glass of fresh lemonade simply because it knows we’re thirsty.

Researchers in Samsung’s Emerging Technology Lab are testing tablets that can be controlled by your brain, using a cap that resembles a ski hat studded with monitoring electrodes, the MIT Technology Review, the science and technology journal of the Massachusetts Institute of Technology, reported this month.

The technology, often called brain computer interfaces, was conceived to enable people with paralysis and other disabilities to interact with computers or control robotic arms, all by simply thinking about such actions. Before long, these technologies could well be in consumer electronics, too.

Some crude brain-reading products already exist, letting people play easy games or move a mouse around a screen.

A brain computer interface, developed by Emotive.Emotive A brain computer interface, developed by Emotive.

NeuroSky, a company based in San Jose, Calif., recently released a Bluetooth-enabled headset that can monitor slight brain movements and allow people to play concentration-based games on computers and smartphones. These include a zombie-chasing game, archery and a game where you dodge bullets — all these apps use your mind as the joystick. Another company, Emotiv, sells a headset that looks like a large alien hand and can read brain waves associated with thoughts, feelings and expressions. The device can be used to play Tetris-like games or search through Flickr photos by thinking about an emotion the person is feeling — like happy, or excited — rather than searching by keywords. Muse, a lightweight, wireless headband, can engage with an app that “exercises the brain” by forcing people to concentrate on aspects of a screen, almost like taking your mind to the gym.

Car manufacturers are exploring technologies packed into the back of the seat that detect when people fall asleep while driving and rattle the steering wheel to awaken them.

But the products commercially available today will soon look archaic. “The current brain technologies are like trying to listen to a conversation in a football stadium from a blimp,” said John Donoghue, a neuroscientist and director of the Brown Institute for Brain Science. “To really be able to understand what is going on with the brain today you need to surgically implant an array of sensors into the brain.” In other words, to gain access to the brain, for now you still need a chip in your head.

Last year, a project called BrainGate pioneered by Dr. Donoghue, enabled two people with full paralysis to use a robotic arm with a computer responding to their brain activity. One woman, who had not used her arms in 15 years, could grasp a bottle of coffee, serve herself a drink and then return the bottle to a table. All done by imagining the robotic arm’s movements.

But that chip inside the head could soon vanish as scientists say we are poised to gain a much greater understanding of the brain, and, in turn, technologies that empower brain computer interfaces. An initiative by the Obama administration this year called the Brain Activity Map project, a decade-long research project, aims to build a comprehensive map of the brain.

Miyoung Chun, a molecular biologist and vice president for science programs at the Kavli Foundation, is working on the project and although she said it would take a decade to completely map the brain, companies would be able to build new kinds of brain computer interface products within two years.

“The Brain Activity Map will give hardware companies a lot of new tools that will change how we use smartphones and tablets,” Dr. Chun said. “It will revolutionize everything from robotic implants and neural prosthetics, to remote controls, which could be history in the foreseeable future when you can change your television channel by thinking about it.”

There are some fears to be addressed. On the Muse Web site, an F.A.Q. is devoted to convincing customers that the device cannot siphon thoughts from people’s minds.

These brain-reading technologies have been the stuff of science fiction for decades.

In the 1982 movie “Firefox,” Clint Eastwood plays a fighter pilot on a mission to the Soviet Union to steal a prototype fighter jet that can be controlled by a brain neurolink. But Mr. Eastwood has to think in Russian for the plane to work, and he almost dies when he cannot get the missiles to fire during a dogfight. (Don’t worry, he survives.)

Although we won’t be flying planes with our minds anytime soon, surfing the Web on our smartphones might be closer.

Dr. Donoghue of Brown said one of the current techniques used to read people’s brains is called P300, in which a computer can determine which letter of the alphabet someone is thinking about based on the area of the brain that is activated when she sees a screen full of letters. But even when advances in brain-reading technologies speed up, there will be new challenges, as scientists will have to determine if the person wants to search the Web for something in particular, or if he is just thinking about a random topic.

“Just because I’m thinking about a steak medium-rare at a restaurant doesn’t mean I actually want that for dinner,” Dr. Donoghue said. “Just like Google glasses, which will have to know if you’re blinking because there is something in your eye or if you actually want to take a picture,” brain computer interfaces will need to know if you’re just thinking about that steak or really want to order it.

Profiles in Science Peter G. Neumann: Rethinking the Computer at 80

One of those is Peter G. Neumann, now an 80-year-old computer scientist at SRI International, a pioneering engineering research laboratory here.

As an applied-mathematics student at Harvard, Dr. Neumann had a two-hour breakfast with Einstein on Nov. 8, 1952. What the young math student took away was a deeply held philosophy of design that has remained with him for six decades and has been his governing principle of computing and computer security.

For many of those years, Dr. Neumann (pronounced NOY-man) has remained a voice in the wilderness, tirelessly pointing out that the computer industry has a penchant for repeating the mistakes of the past. He has long been one of the nation’s leading specialists in computer security, and early on he predicted that the security flaws that have accompanied the pell-mell explosion of the computer and Internet industries would have disastrous consequences.

“His biggest contribution is to stress the ‘systems’ nature of the security and reliability problems,” said Steven M. Bellovin, chief technology officer of the Federal Trade Commission. “That is, trouble occurs not because of one failure, but because of the way many different pieces interact.”

Dr. Bellovin said that it was Dr. Neumann who originally gave him the insight that “complex systems break in complex ways” — that the increasing complexity of modern hardware and software has made it virtually impossible to identify the flaws and vulnerabilities in computer systems and ensure that they are secure and trustworthy.

The consequence has come to pass in the form of an epidemic of computer malware and rising concerns about cyberwarfare as a threat to global security, voiced alarmingly this month by the defense secretary, Leon E. Panetta, who warned of a possible “cyber-Pearl Harbor” attack on the United States.

It is remarkable, then, that years after most of his contemporaries have retired, Dr. Neumann is still at it and has seized the opportunity to start over and redesign computers and software from a “clean slate.”

He is leading a team of researchers in an effort to completely rethink how to make computers and networks secure, in a five-year project financed by the Pentagon’s Defense Advanced Research Projects Agency, or Darpa, with Robert N. Watson, a computer security researcher at Cambridge University’s Computer Laboratory.

“I’ve been tilting at the same windmills for basically 40 years,” said Dr. Neumann recently during a lunchtime interview at a Chinese restaurant near his art-filled home in Palo Alto, Calif. “And I get the impression that most of the folks who are responsible don’t want to hear about complexity. They are interested in quick and dirty solutions.”

An Early Voice for Security

Dr. Neumann, who left Bell Labs and moved to California as a single father with three young children in 1970, has occupied the same office at SRI for four decades. Until the building was recently modified to make it earthquake-resistant, the office had attained notoriety for the towering stacks of computer science literature that filled every cranny. Legend has it that colleagues who visited the office after the 1989 earthquake were stunned to discover that while other offices were in disarray from the 7.1-magnitude quake, nothing in Dr. Neumann’s office appeared to have been disturbed.

A trim and agile man, with piercing eyes and a salt-and-pepper beard, Dr. Neumann has practiced tai chi for decades. But his passion, besides computer security, is music. He plays a variety of instruments, including bassoon, French horn, trombone and piano, and is active in a variety of musical groups. At computer security conferences it has become a tradition for Dr. Neumann to lead his colleagues in song, playing tunes from Gilbert and Sullivan and Tom Lehrer.

Until recently, security was a backwater in the world of computing. Today it is a multibillion-dollar industry, though one of dubious competence, and safeguarding the nation’s computerized critical infrastructure has taken on added urgency. President Obama cited it in the third debate of the presidential campaign, focusing on foreign policy, as something “we need to be thinking about” as part of the nation’s military strategy.

Australians Surge in Quest to Build Quantum Computer

In an article that appeared on Thursday in the journal Nature, a team of Australian and British scientists, led from the University of New South Wales, reported that they had successfully constructed one of the basic building blocks of modern quantum computing by relying on manufacturing techniques now used by the modern semiconductor industry.

Quantum computing will potentially lead to a new generation of supercomputers that are not intended to replace today’s machines but will instead open new computing vistas, from drug and material design to code breaking, by offering speed to address a new class of problems.

“We are used to designing cars and airplanes with computers,” said Andrew Dzurak, a physicist who is director of the Australian National Fabrication Facility and lead researcher on the latest advance. “Imagine if you could start building your molecule or your material on a computer and then completely simulate its behavior.”

The basic building blocks of quantum computers are quantum bits, or “qubits.” Unlike today’s digital computers, which process information in a binary fashion based on logic states of “on” and “off,” a qubit can for brief periods represent multiple states simultaneously. Potentially, this means it is possible to tackle vast new problems by performing parallel computations using a relatively small set of qubits — perhaps as few as several hundred. The advance by Dr. Dzurak’s team involves placing a single electron — embedded in a silicon chip — in a “quantum state,” and then repeatedly measuring the state.

In February, a second group based at the University of New South Wales published an article in the journal Nature Nanotechnology reporting their advance: the construction of a single-atom transistor using a different but related design approach.

In both cases, the research teams are international. There is an increasing awareness, however, that Australian scientists have made significant advances this year toward this long-promised new type of computing.

While there is a growing consensus among scientists that working quantum computers will emerge during this decade, there is also a growing belief that they will not replace the conventional computers that are now carried in the pockets of more than half the world’s population. For one thing, most of the quantum computing approaches only worked when temperatures were cooled to near absolute zero.

Though there are only a handful of workable algorithms designed to run on quantum computers, scientists say their application may prove vastly more useful than today’s technology in simulating a wide variety of biological, chemical and physical systems. That means they could become the standard tool for a wide range of new industries, like drug and material design.

The achievements of the two teams is a payoff from an investment the Australian government began making in the 1990s.

“Both groups are highly competitive and leading in the world in what they do,” said Gerhard Klimeck, a professor of electrical and computer engineering at Purdue, who has collaborated with both groups and was a co-author of the Nature Nanotechnology paper.

Dr. Dzurak’s group’s work contrasts with a research team led by Michelle Simmons, director of the ARC Center for Quantum Computation and Communication Technology at the University of New South Wales. That group has taken an approach based on placing individual atoms using a scanning tunneling microscope, allowing great precision in building devices on an atomic scale.

The team led by Dr. Dzurak uses conventional semiconductor techniques to implant a phosphorus atom just 10 to 15 nanometers below the surface of a silicon chip. That approach has the twin advantages of using industry standards and potentially extending the individual electron’s duration in a quantum state.

The United States has federally financed, corporate and university research efforts under way to design usable quantum computers. I.B.M., for example, recently expanded its research at its Almaden laboratory in California.

Andreas Heinrich, a physicist who is a quantum researcher at I.B.M., pointed out that neither Australian group had shown the ability to interconnect multiple qubits. That capability is necessary for a quantum computer.

Dr. Dzurak said he believed that capability could be achieved as soon as a year from now.
