Apple and Xerox PARC – Did Steve Jobs steal everything from Xerox’s Palo Alto Research Center?

Rich Neighbor with Open Doors

It is claimed again and again that in the course of the Macintosh’s development, Apple just resorted to the ideas the research laboratory Xerox PARC had hatched before. Fact or Fiction?

The myth entwines about a late 1979 visit to Xerox PARC by a group of Apple engineers and executives led by Steve Jobs. Alex Soojung-Kim Pang, author of “Making the Macintosh”, writes:

According to early reports, it was on this visit that Jobs discovered the mouse, windows, icons, and other technologies that had been developed at PARC. These wonders had been locked away at PARC by a staff that didn’t understand the revolutionary potential of what they had created. Jobs, in contrast, was immediately converted to the religion of the graphical user interface, and ordered them copied by Apple, starting down the track that would eventually yield the Lisa and “insanely great” Macintosh. The Apple engineers– that band of brothers, that bunch of pirates– stole the fire of the gods, and gave it to the people.

It’s a good story. Unfortunately, it’s also wrong in almost every way a story can be wrong. There are problems with chronology and timing. The testimony of a number of key figures at Apple suggests that the visit was not the revelation early accounts made it out to be. But the story also carries deeper assumptions about Apple, Xerox PARC, computer science in the late 1970s, and even the nature of invention and innovation that deserve to be examined and challenged.

Let us take a closer look at what happend at Xerox PARC:

 

 

In the Untied States, the brand name “Xerox” denotes photocopying just as “Kleenex” stands for tissues or “Scotch tape” for adhesive film. After all, already in 1950, the Xerox Corp. was the world’s first company to actually transfer the “Xerography” invented by the American law student Chester Carlson into a functional product. Carlson received in 1937 a patent for a process that he called ”electrophotography.” On 22 October 1938 followed the premiere in practice: With the help of a metal plate was coated with sulfur and a lamp Chester the lettering ”10-22-38 Astoria” on a wax paper.

By the end of the sixties, the Xerox management sensed the threat of Japanese companies catching up on Xerox’s technological advantage. Moreover, the Xerox head worried that the “paperless office” might emerge with the following computer generations, in which the Xerox would no longer have a place. Against this background, the Xerox Palo Alto Research Center (PARC) in California was founded in 1971. John Warnock, former researcher in the Xerox PARC and later one of the two founders of Adobe Systems, remembers: “The atmosphere was electric – there was total intellectual freedom. There was no conventional wisdom; almost every idea was up for challenge and got challenged regularly.” Larry Tessler, who later took part in developing the Macintosh and the Newton PDA at Apple, also enjoyed the liberties the PARC provided in the seventies: “The management said go create the new world. We don’t understand it. Here are people who have a lot of ideas and tremendous talent, [are] young, energetic.” The problem, however, was that the company management at the East Coast of the USA did not [care a straw for] the PARC’s research results unless they were directly involved with photocopiers.

Within two years, the researchers at the PARC had designed the Alto, which was something like the first personal computer. The Alto did not feature character-oriented graphics, as did all the other computers of that time, but a bit-oriented version instead. A high quality printer could print exactly what the screen displayed.

However, this marvelous machine was not freely available on the market. Approximately 1500 units had been produced, 1000 of which Xerox employed in-house; the rest went to universities and public authorities.

Commercial for the Xerox Alto (1972).

This commercial for Xerox’s Alto computer released in 1972 introduced the world to the first desktop computer with a graphical user interface. Named after Xerox PARC’s home city of Palo Alto, California, the computer introduced the world to the window-oriented mouse and keyboard interface we use today. The Alto also had a distinctive portrait screen — an idea that was well before its time.

The video showed how the computer could revolutionize your office life, with email, word processing and reminders all controlled by a cursor. It also shows the protagonist expressing his thoughts and actions out loud, as if in conversation with the Alto (which seems to be nicknamed “Fred”).

Some Apple engineers were already familiar with PARC, its work, or technologies like the mouse. Bill Atkinson had read about Smalltalk as an undergraduate. Some had worked at PARC: Jef Raskin spent time there during a sabbatical year at Stanford, and had a number of friends who were researchers there. Finally, there were even some Apple employees whose had learned about the mouse while working for Douglas Engelbart at SRI in the 1960s and early 1970s, or Tymshare in the later 1970s.

There were actually two visits by groups from Apple to Xerox PARC in 1979. Steve Jobs was on the second of the two. Raskin, who helped arranged both visits, explained that he wanted Jobs to visit PARC to understand work that was already going on at Apple. The Macintosh project had escaped the chopping block several times, and Raskin had tried to explain to Jobs the significance of the technologies it was incorporating. By showing that other companies considered this kind of work exciting, Raskin hoped to boost the value of the Macintosh’s work in Jobs’ eyes.

Raskin, who had been charged initially with the Macintosh project at Apple, tried to convince the Apple management to employ a graphical user interface like the Alto contained in the development of the Lisa. According to Raskin, it was not until Bill Atkinson supported him that Jobs set out for the PARC.

Whatever way the contact was actually accomplished, this visit meant a turning point to the life of Steve Jobs; the three technologies that the 24-year-old encountered there were each revolutionary on their own: the first graphical user interface for computers; networked Alto computers; and object-oriented programming.

Even 17 years after this visit, Jobs can still remember it exactly:

They showed me really three things. But I was so blinded by the first one I didn’t even really see the other two. One of the things they showed me was object oriented programming – they showed me that but I didn’t even see that. The other one they showed me was a networked computer system… they had over a hundred Alto computers all networked using email etc., etc., I didn’t even see that. I was so blinded by the first thing they showed me, which was the graphical user interface. I thought it was the best thing I’d ever seen in my life. Now remember it was very flawed, what we saw was incomplete, they’d done a bunch of things wrong. But we didn’t know that at the time but still thought they had the germ of the idea was there and they’d done it very well and within you know ten minutes it was obvious to me that all computers would work like this some day.

Jobs decided to realign Apple’s strategy and fully rely on the “graphical user interface” (GUI) he had seen at the Xerox PARC.

Adele Goldberg, who had been a researcher at the PARC at that time, already suspected that Jobs’ visit would entail extensive consequences: “He came back, and I almost said ‘asked’ but the truth is ‘demanded,’ that his entire programming team get a demo of the Smalltalk System, and the then head of the science center asked me to give the demo because Steve specifically asked for me to give the demo, and I said ‘no way.’ I had a big argument with these Xerox executives, telling them that they were about to give away the kitchen sink, and I said that I would only do it if I were ordered to do it, cause then, of course, it would be their responsibility, and that’s what they did.”

Steve Jobs had his own reasons for visiting PARC. Apple bought access to the PARC by means of a stock deal that seemed lucrative to the Xerox managers on the East Coast: They might buy 100,000 Apple stocks for one million dollars. Holding this admission ticket in the hand, Steve Jobs, Apple’s president Mike Scott, Bill Atkinson, and a number of members of the developing team marched up. “I think mostly … what we got in that hour and a half was inspiration and just sort of basically a bolstering of our convictions that a more graphical way to do things would make this business computer more accessible.”

Larry Tesler, who then took part in the demo as an employee of the PARC, had been fascinated by the visitors: “After an hour looking at demos, they understood our technology and what it meant, more than any Xerox executive understood after years of showing it to them,” Tesler told Robert X. Cringley in the PBS-Show “Triumph of the Nerds” (1996).

In late 2011 after Steve Jobs death Tesler recalled Steve Jobs’ visit at an event at the Churchill Club:

Steve Jobs’ visit of the Xerox Palo Alto Research Center in 1979 became in 1999 a topic in the movie “Pirates of Silicon Valley”. The narrator in this scene (role of Steve Wozniak”) says more or less, that the Apple guys got a “miracle bag” from Xerox: the idea of the WYSIWYG, the mouse-driven graphical user interface – “like rich people giving junky old stuff to the Salvation Army, only the junk turns out to be a Rembrandt.”

But to be fair: The movie does not tell the whole story: Yes, the Macintosh team took up the ideas of the Xerox PARC, but it also changed numerous operating modes and added countless new features. Accordingly, the Xerox Alto did not imply, for example, menus flapping down from the upper edge of the screen, but operated with some kind of a pop-up window instead. Moreover, the window did not open automatically by double-clicking on a document, but had to be opened manually. During months of painstaking work, Atkinson had written the QuickDraw routine for the Lisa and the Macintosh, which allowed for overlapping windows to be drawn on the computer screen for the first time.

Macintosh-Developer Andy Hertzfeld said in an Interview with CNET:

Q: What’s your response when people say the Mac engineers stole everything from Xerox’s Palo Alto Research Center?
A: I just say, well, someone doesn’t know what they’re talking about. Maybe in the very broadest sense we were inspired by Xerox. But literally no code was taken, I mean not a single line of code.
Q: Didn’t a lot of people join Apple from Xerox?
A: Just one person on the Mac team, more on the Lisa team–four or five. Many of the ones who came from PARC came after the Mac shipped. Alan Kay, who was the visionary and driving force behind Xerox PARC, came to work at Apple just about the time I was leaving, in March 1984. Once he came there, about 10 PARC people came.

 

The screen of the Xerox Star

In contrast to the first Mac, the Alto featured no completed desktop metaphor nor ingenious desktop icons such as the trash can, which made it easier to delete files, and not just for computer novices. The historical accomplishments of the Mac team also included the Macintosh Human Interface Guide, which, for instance, when it detected a document in a Macintosh application, determined that it was to be saved using the command “Apple-S.”

As for Xerox, the bitter aftertaste of having missed an historical opportunity remained, particularly due to the fact that parallel to the Apple developers, Bill Gates and his Microsoft crew also went in and out as they pleased. (By the way, they did so without holding an admission ticket comparable to the one Jobs had procured by means of the stock deal.)

“Basically, they were copier heads that just had no clue about a computer or what it could do. And so they just grabbed defeat from the greatest victory in the computer industry. Xerox could have owned the entire computer industry today,” Steve Jobs said in 1996. “Could have been, you know, a company ten times its size. Could have been IBM – could have been the IBM of the nineties. Could have been the Microsoft of the nineties.”
Besides, in the context of the dispute with Apple about the plagiarism accusations around the first Windows versions, Microsoft had pointed out that Apple and Microsoft had both helped themselves generously at XEROX.

In the early ’80s Steve Jobs needed help from Bill Gates: Apple was developing its first Macintosh. Microsoft, which had supplied IBM with the MS-DOS operating system for its PCs, was invited to be the Mac’s first software developer. Early Mac developer Andy Hertzfeld says that when Jobs recruited Microsoft he feared it “might try to copy our ideas into a PC. Steve made Microsoft promise not to ship any software that used a mouse – until at least one year after the first shipment of the Macintosh”.
In 1983, Microsoft sprang a surprise with a new operating system for PCs using an interface like the Mac’s – Windows. Jobs “went ballistic”, demanding an explanation and saying: “I want him in this room by tomorrow afternoon, or else.”
Gates arrived alone to find himself surrounded by 10 Apple employees. “You’re ripping us off,” Jobs shouted.
But Gates looked him in the eye, and said in his squeaky voice, “Well, Steve, I think there’s more than one way of looking at it. I think it’s more like we both had this rich neighbour named Xerox and I broke into his house to steal the TV set and found out that you had already stolen it.”
This episode is described slightly exaggeratedly in the movie “Pirates in the Silicon Valley”:

Apple sued Microsoft in 1988. Six years later a judge threw the case out.

James Turner from O’Reilly News interviewed Andy Hertzfeld, one of the original designers of the Macintosh and author of the book, Revolution in the Valley: The Insanely Great Story of How the Mac Was Made, which chronicles the efforts to create the Mac. Andy Hertzfeld currently works at Google as a Software Engineer. In this Interview James Turner asked some questions about Xerox PARC and the development of the Mac:

JT: In your book you allude to Xerox as being, to Bill Gates, the rich uncle that both Apple and Microsoft stole from. What was the relationship like with PARC when you were developing the Mac and how did the Xerox researchers feel about the Mac?

AH: Well, we had no formal relationship with PARC while we were developing the Mac. We got a single demo before the Mac project got off the ground, when the LISA project, that sort of cousin or bigger brother of the Mac, was in development. And so from that one demo we were already pointed in that direction but I would say that Xerox PARC demo galvanized and reinforced our strong opinion that the graphic user-interface was the way to go. And then the influence of PARC was strong in the project, but not through a formal relationship with PARC; more through PARC people getting wind of what we were doing and coming to work at Apple. The very first one was Tom Malloy on the LISA project. He was sort of a disciple of Charles Simonyi–I write about that a little bit in my book. He was one of the original LISA people who came to Apple in 1978. But later, Larry Tessler was a really key figure coming to the LISA team in the summer of 1980 from Xerox PARC and eventually, mostly after the original Mac shipped, there were a dozen or more. Another person I have to mention is Bruce Horn who started working at Xerox PARC when he was 14 years old; he was one of those kids they picked from a Palo Alto High School to teach Smalltalk to and he was one of the four or five key Macintosh developers. And of course he was steeped in all of the PARC values and through Bruce, a lot of them made it into the Macintosh.

JT: Was there any feeling among the Apple engineers that any – guilt is probably too strong a word, but feeling like you know Xerox had these great ideas. I guess Xerox really let them go to waste but–

AH: Oh there was nothing like that; Steve Jobs has a good quote. It’s actually a Picasso quote that he often cites; he cited it at one of our retreats which was sort of good artists copy; great artists steal. And what that means is that when you’re passionate about what you’re doing you’ll take ideas from anywhere and with no guilt. You want to make the best possible thing and that was our mentality.

JT: I have to say I actually worked for Xerox AI Systems in 1986 and it was kind of frustrating because they really had the mentality there that if you couldn’t sell paper and toner for [them] they weren’t interested.

AH: Oh sure. Xerox in a well-documented fashion – they had at least the possibility of having the world at their feet there with the work that Alan Kay and his team did. But yeah; they completely blew it and most of the best PARC people were really frustrated by the Xerox management. There’s no doubt of that; that’s one of the reasons why Steve Jobs is great. You had someone leading the company who could relate to the customers and appreciate things.

Interview CNET with Andy Hertzfeld

What’s your response when people say the Mac engineers stole everything from Xerox’s Palo Alto Research Center?
I just say, well, someone doesn’t know what they’re talking about. Maybe in the very broadest sense we were inspired by Xerox. But literally no code was taken, I mean not a single line of code.

Just one person on the Mac team, more on the Lisa team–four or five. Many of the ones who came from PARC came after the Mac shipped. Alan Kay, who was the visionary and driving force behind Xerox PARC, came to work at Apple just about the time I was leaving, in March 1984. Once he came there, about 10 PARC people came.
What was the attraction, that Apple could get the technology into the market?
Yeah, sure. The people developing the stuff at Xerox PARC were different types of people. Some were professorial and academic, and they didn’t really care if their stuff was used by people. They just wanted to explore new ideas. They were happy there. But the people who wanted to make an impact on the world and improve the lives of their friends and stuff like that, they were very frustrated–nothing ever came out. So they saw Apple come out with something that embodied all of their ideals, but their kid brother could afford it. They were very attracted to that. They came to Apple to make a difference.
