I knew Larry Tesler as a colleague, friend, member of my research group, manager, etc. for more than 50 years, almost as long as I knew Bert Sutherland. There is an excellent obit for Larry at: https://gizmodo.com/larry-tessler-modeless-computing-advocate-has-passed-1841787408 https://gizmodo.com/larry-tessler-modeless-computing-advocat... ... and I expect another one from John Markoff -- who was a friend of his -- in the NYTimes. In many ways, Larry did too many interesting things and had so much influence in too many areas for there to be any chance to characterize him technically. In short, he was a superb wide-spectrum(real) computer scientist who was also a very talented and skilled programmer. His passing was sudden and unexpected, and I may return later to this note to add more details of his rich career. For now, I remember him as great to work with in all aspects of his life. He was a great guy, and perhaps that sums him up as best as can be.

Is anyone from Parc still involved in research these days? Or is everyone retired or just chugging along at regular corporate jobs?

  Most of the people who were at Parc who are still alive are still doing research. Pretty much only one wanted to get rich (and did). Several were more or less forced into becoming rich. Money has its own dynamics and none of these folks wound up doing further research. But Butler Lampson (the "Oppenheimer" of Parc) is still going strong, as am I and many others. It was a calling, never a job.

      I think Alan Kay is referring to Charles Simonyi. According to Forbes, his net worth is $4.3 billion: https://www.forbes.com/profile/charles-simonyi/ https://www.forbes.com/profile/charles-simonyi/

        I was thinking of Eric Schmidt. A quick check shows a net worth of $14.7 billion.

    When I was 17-18, I read 'Dealers of Lightning' it clued me into the foundations laid for modern computing in the 60-70's in the Bay Area (between SRI, CSAIL and PARC), and markedly changed my own approach to information and computing. I've always wondered how those who were featured in the book felt about it?

      The best book about the ARPA/Parc research community (Parc sprouted from ARPA) is "The Dream Machine" by Mitchell Waldrop: it is both the most complete and most accurate. "Dealers of Lightning" is at the next level but far from the bottom. Its flaws are too much "Heroes' Journey" and a very complex and confused jumping around timeline (I had trouble myself orienting in some of the spots). But it also has a lot of good stories, of which a reasonable number are "true enough". "Fumbling The Future" is extremely inaccurate.

        Thanks! I'll add that one onto my reading queue. I actually didn't have too much trouble following Dealers, because it (more or less) mostly followed each project separately, which while creating an interspersed timeline in the book, was mostly coherent within each section. I did read at least part of Fumbling, but I found it a hard book to thread the needle on, and it was in such stark factual disagreement with what else I'd read that I don't recall finishing it. I know too many who draw the same conclusions from the Alto and related technologies that fumbling does, so I try to get people to read more about PARC, because I'll hope that once they know more they'll draw much the same conclusions I have - My frustration with much of the traditional criticism of Xerox in failing to commercialize the PARC innovations is it completely ignores both the high cost of the technology (it was literally the technology of the future) and the sales culture of technology at the time. I don't think any large technology company (which Xerox was broadly) could have made something wondrous out of the innovations PARC created because the people who could recognize the value (and use) of this kind of technology were not the people being sold to, or for that matter doing the buying - nor did they have the budgets to buy a Alto, as was later seen with the Star when it came out. It took direct to consumer sales (allowing department managers to buy stuff), and lower cost products to allow personal computing to penetrate into the home and corporate america - also the traditional criticism completely ignores that the 9700 (and follow on products) paid for the money spent at PARC several times over. (incidentally, I believe that this sales culture issue is a prime reason why DEC no longer exists as a company because they failed to see that their market was shifting and could no longer be sold thru the same mechanisms they always had been) In the end, basic research and the undirected applied science that flows from it is important, even if it has no direct tie to your line of business, because it's the innovation that drives a company forward, and frankly drives humanity forward. I wish more people knew that modern interconnected the world we live in was built on billions spent with no firm idea of what would result from them, and how much of a debt we owe to PARC, Bell Labs and others. Also, thank you for taking the time to respond to my question!

    "It was a calling, never a job." - This is so heart-warming to read, in a world where the lust for more and more money seems to be so depressingly high at times.

    Looking at all of the work that came out of Parc during your time there... What drew you to that company to begin with? I find it amazing that so many of the Big Names in computer science/software engineering came from the same place.

      Parc was an "extension" or "outgrowth" of the ARPA (before the "D") sponsored computer research in the 60s that was catalyzed by Congress overreacting to Viet Nam protests and changing ARPA's charter for the worse. ARPA/Parc as a community had the best and most enlightened funding for computing research starting in 1962 (Parc started in 1970), and a very large percentage of the familiar technologies of today -- including personal computing, tablets, dynamic OOP, the GUI, the Internet, etc -- were invented by it. The best (and pretty accurate) book about this remarkable group is "The Dream Machine" by Mitchell Waldrop. Bob Taylor, who had been a director of the ARPA computing research, looked for a way to fund some of the "ARPA Dream" projects that Congress was curtailing, and found Xerox (which wanted to set up a longer range research lab). Taylor was particularly interested in recruiting a number of the young Phds that ARPA had funded, and I was one of them.
