In November 1952, a Harvard sophomore, Peter G. Neumann, had a two-hour breakfast with Albert Einstein, through which they mentioned the physicist’s philosophy that “The whole lot ought to be made so simple as potential, however no easier.”
Einstein’s aphorism led to a lifelong romance with each the sweetness and the perils of complexity for Dr. Neumann, who went on to grow to be one of many nation’s main laptop safety researchers.
Dr. Neumann died on Sunday on the Santa Clara Medical Middle in Santa Clara, Calif. He was nonetheless working full time on a Pentagon-supported superior laptop safety design, which is being adopted by corporations comparable to Google and Microsoft. He was 93.
The reason for dying was problems from a current fall, his daughter, Helen Neumann, mentioned.
Dr. Neumann (pronounced NOY-man), who has labored as a pc scientist and safety researcher at SRI International in Menlo Park, Calif., since 1971, has lengthy been a voice within the wilderness warning about a pc trade that has been liable to repeatedly make the identical errors.
In 2010, Mr. Neumann launched a analysis challenge that investigated learn how to defend towards the most typical forms of safety vulnerabilities. Funded by the Protection Superior Analysis Tasks Company, or Darpa, this system, often called Cheri, developed a brand new method to laptop {hardware} that restricts software program packages in order that malicious directions are unimaginable to execute.
An analogy could be changing a grasp key that opens each door in a constructing with a set of keys that every solely open the precise rooms their holder is allowed to enter — and making it bodily unimaginable to repeat or modify them.
Lately an trade group often called the CHERI Alliance has begun to commercialize the design for client merchandise and industrial functions.
“Peter Neumann is each one of many final of the outdated guard and a pointer to the long run,” mentioned Whitfield Diffie, a mathematician and cryptographer who’s the co-inventor of public key cryptography. “He describes himself as having had a 70-year profession in laptop science, beginning along with his commencement from Harvard, and he has all the time advocated beginning with {hardware} designed to assist safety.”
Starting in 1985, Dr. Neumann served as editor for the Association for Computing Machinery Risks Forum newsgroup, an influential assortment of emails from readers reporting laptop failures and foibles that has an avid following of a whole bunch of hundreds.
Since then, he has maintained the sprawling compendium of laptop failures, flaws, foibles and privateness points, annotating every of the three,195 points with wry feedback and the occasional pun. In 1995, the listing turned the idea for his e-book, “Computer-Related Risks.”
Within the Nineteen Nineties, he was a key researcher on a Darpa-funded analysis challenge to develop new methods to detect intruders in massive laptop networks. Often known as Emerald, the challenge didn’t result in a profitable business spinoff, however SRI gained a number of lawsuits towards Silicon Valley corporations for utilizing the know-how and not using a license.
Regardless of his affect within the laptop safety world, Dr. Neumann most well-liked to keep up a low profile.
“There’s no restrict on the impression {that a} small group can have in the event that they don’t care who will get credit score,” mentioned Patrick Lincoln, the office director of Darpa’s Information Innovation Officewho described Dr. Neumann as routinely working behind the scenes with out credit score. “The world is simply a lot a greater place for having had Peter.”
Dr. Neumann had been a frequent critic of the lax attitudes the trade has maintained towards each laptop safety and particular person digital privateness.
“I’m essentially an optimist with regard to what we will do with analysis,” he mentioned. “I’m essentially a pessimist with respect to what companies who’re essentially beholden to their stockholders do, as a result of they’re all the time engaged on short-term look.”
Peter Gabriel Neumann was born on Sept. 21, 1932, in Manhattan. His father was Israel Ber Neumann, a famous artwork seller, working first in Germany after which in New York, the place he opened the New Artwork Circle gallery after shifting to the USA in 1923. Dr. Neumann’s father fled to America shortly after discovering himself seated close to Adolf Hitler in a German restaurant.
His mom, Elsa Schmid Neumann, was a mosaic artist. Dr. Neumann’s two-hour breakfast with Einstein befell as a result of his mom had been commissioned to create a colourful mosaic of Einstein and had grow to be pleasant with him. The mosaic was displayed for a few years in a reference studying room in the principle library at Boston College.
Dr. Neumann grew up within the Greenwich Village neighborhood of Manhattan earlier than his household moved to Rye, N.Y., the place he attended highschool. He took his first computing job over a summer time when he was in faculty, which concerned programming an IBM card-punched calculator for the U.S. Naval Ordnance Laboratory.
He entered Harvard in 1950 and have become one of many first laptop hackers throughout his senior yr. The time period initially described individuals who had been fascinated by the machines, slightly than the later that means referring to those that broke into laptop networks.
At Harvard, he was one of many first programmers to have solo entry to his personal “private” laptop — at the very least, on weekends. He had the run of a pc often called the Mark IV. The Mark IV was one of many world’s first stored-program computer systems, and in 1954 Dr. Neumann earned the belief of its designer, Howard Aiken. Each Friday at 5 p.m., he would take over the care of the machine from its common operators. He would have the run of the system for the weekend and wouldn’t go away till Monday morning.
“I used to be the operator, maintainer and guru,” he mentioned. With one other scholar, Fredrick P. Brooks Jr.who would go on to grow to be an IBM laptop designer, Dr. Neumann wrote a paper on utilizing the Mark IV to compose music.
After spending two years in Germany on a Fulbright fellowship, Dr. Neumann obtained his Ph.D. in arithmetic from Harvard and joined Bell Laboratories in 1960. He spent a decade there and have become a key developer of the Multics operating systeman early Pentagon-financed challenge that was the primary systematic try to grapple with learn how to share laptop assets securely amongst many customers.
Multics (Multiplexed Info and Computing Service) was developed collaboratively by researchers on the Massachusetts Institute of Expertise, Bell Laboratories and the Honeywell Company starting within the mid-Nineteen Sixties. The challenge pioneered ideas that turned foundational to fashionable computing.
Dr. Neumann retained a lifelong ardour for music, taking part in quite a lot of devices, together with the bassoon, French horn, trombone and piano, in quite a few musical teams. At laptop conferences, he often led his colleagues in Gilbert and Sullivan songs.
In December 2024, Dr. Neumann made an nameless $4 million donation to the San Francisco Symphony to avoid wasting its refrain, his daughter, Helen, mentioned.
She is his solely survivor. He was married twice. His first marriage, to Anne Ferris Rittershofer, resulted in divorce. His second spouse, Elizabeth Susan Neumann, died in 2020. Two sons, John and Christopher, predeceased him.
Dr. Neumann had occupied the identical workplace at SRI Worldwide since arriving as a pc researcher in 1971. Till the constructing was modified to make it earthquake-resistant, the workplace had attained notoriety for the towering stacks of laptop science literature that crammed each cranny.
Legend has it that colleagues who visited the workplace after a 1989 earthquake had been shocked to find that whereas different workplaces had been in disarray from the 7.1-magnitude quake, nothing in Dr. Neumann’s workplace appeared to have been disturbed.
