Does anyone have a better article? I can't find any other information about it. I found out from the NYC Lisp mailing list, and Wikipedia confirmed it.

Sad, sad, sad day. :(

Do you have a source (i.e. link to the mailing list)? Unfortunately the person who added it to the Wiki article didn't add one.
The archives to the mailing list are private, so I can't link. You can see in the wikipedia history that who ever made the edit claims to have received word from McCarthy's sister.
Yeh; unfortunately that's not a strong enough source, particularly for this sort of edit :)

Thanks anyway - I am sure it will appear in time.

Usually stuff like this is legit; but sometimes it isn't. So the policy is to have a reliable source or nothing.

I tweeted at @stanfordeng, hoping that they can confirm.
For what it's worth, it was just posted to the University of Waterloo CS announcement list:

"I just received news that John McCarthy passed away in his sleep a few hours ago; he was at home."

What a terrible month for computing...
My thoughts exactly. It's been a black month for computing.
I have a feeling this will start being a lot more common in the computer world. The founders of everything are starting to hit their later ages. :(
Yes.One of the more exciting things about computer science, a few decades ago, is that it was all brand new. Even the pioneers were contemporaries. These were exciting times to live in, since it made me feel like we were on the edge of a brand new technology.

But now, the pioneers have gotten old. And the excitement is slowly ebbing away.

With all these great minds from our field passing away, I'm beginning to think we should pause for a moment and think what we could do to thank all those legendary computing figures still with us? Knuth, Kernighan and Woz come to mind, certainly there are a lot more.
Time for the black bar to appear at the top of Hacker News?
Yes. Unless the information is actually inaccurate, there's not even any question.

What an amazing pioneer. He will be missed.

For a fun portrait of McCarthy's early life and aspirations, see the passages about him in "What the Doormouse Said". [1]

- Born to communist activists in 1920s Boston

- Studied math with John Nash at Princeton

- Organized the first computer-chess match in 1965, pitting his own algorithm against one created by computer scientists in the USSR, with moves communicated by telegraph.

While many will remember him for Lisp and his contributions to AI, perhaps equally important was his role in running a research lab in what became a characteristic West Coast fashion: finding intelligent people, setting them free to do what they wanted, and obdurately arguing with them over very little provocation. He was far enough from mainstream to be familiar, and even sympathetic to the 60s counterculture, but also cynical enough to embrace technology, rather than revolution, as a way forward. If this sounds a bit like running a startup today, there's one main reason it does: John McCarthy.

Excellent book BTW, would recommend it to anyone interested in the history of not just computing but what we think of as UI/UX.

It's almost depressing to see the same problems we keep (re-)solving have had great minds beating on them for quite a while now :)

Whether or not he has passed; if anyone has the book and fancies spending a little time adding interesting material to the WP article about him, that would be nice :)
I wonder if the chess match had any influence on the movie "Colossus: The Forbin Project"
Anyone got a reliable source corroborating this?
The WikiPedia history states that there was some personal communication with his sister.

Long live the first Knight of the Lambda Calculus!
This seems to be the original tweet http://twitter.com/#!/wendyg/status/128554733714669568
Not to be "that guy", but does she have any connection to him? Why should I believe she isn't just some random that made that up?
As a guy on the internet I am pretty sure she didn't make it up.

I think we will have to wait for confirmation, but not long.

Steve Jobs, Dennis Ritchie, and now John McCarthy - maybe some truth that deaths always come in 3's. Quite unnerving.

We should propose National Computing Month or something for October.

Poisson distribution? I wish I knew more probability and statistics to understand why this happens.
The explanation could be simpler than that: you just don't notice when notable deaths don't clump together.
You can take any arbitrary, long running sequence and partition it into threes. Also: selection bias.
To quote the wise _Principia Discordia_:

> "I find the Law of Fives to be more and more manifest the harder I look."

I confess that when the news about Dennis Ritchie was posted, I immediately flashed to the thought, "who's number three?"

Thing is, so did a lot of other people, and tagging John McCarthy's WP page in this way would be just the sort of prank/hoax that would inspire. So the "deaths come in threes" aphorism makes me more suspicious of this, not less.

He has a string of accomplishments that still live on in active development... and he made it to 84. That's a good run.
(he (will (be (dearly (missed)))))
((will-be (dearly missed)) he)

FTFY

Whenever people make Lisp jokes by nesting parentheses without regard for the semantics that they denote, I get a little disappointed. It's not anger, nor contempt; just a feeling that we can do better.

    (will-be 'john-mccarthy (modifier 'missed 'dearly))
Incidentally, "I feel like we can do better" would probably be a pretty good summary of what John McCarthy was about.
I thought about doing something like that, but decided against it. I'm expressing condolences, not writing an obituary program!
It would at least be nice to have the parentheses in some sense represent the parse tree for the sentence, like:

(He (will be) (dearly missed))

That's not very Lispy, and I'm sure some linguists would have a thing or two to say about my tree, but it at least has a structure related to the meaning.

Or,

    (assert (equal 'dearly (missed-amount 'john-mccarthy)))
You should put more effort into your Lisp parody.
((not (parody?)) 'homage)

It's maybe a not very well known fact but McCarthy's original LISP proposal used M-expressions instead of S-expressions; M-expressions were then transformed into S-expressions. Using S-expressions directly, however, turned out to be more popular amongst programmers.

With M-expressions, this would look like: he[will[be[dearly[missed]]]]

I wish they had went with M-expressions, I'd be able to make Obj-C and Lips jokes at the same time!
(will-miss 'john-mccarthy :dearly t)
This really needs a better source. There's no citation provided, and Wikipedia can't keep any details of his death up without one.

Basically, I have a spoonful of salt to hand.

Yes, there isn't any news about this.

This might be a good way to make people read about this kind of person.

Agreed. I did a quick Google News search and turned up nothing. Could be legit, or vandalism, but there's really no way to know until we have confirmation.

--EDIT-- Since I wrote this, I've seen one source appear, in Portuguese[1]. It's still unclear whether this story is legitimate, or if they simply copied wikipedia / the buzz surrounding the story.

-

--EDIT 2-- Globo is apparently the largest media conglomerate in South America[2] and thus unlikely to publish unsourced stories, so this looks (sadly) to be true.

This news site supports the claim (if you translate it): http://g1.globo.com/tecnologia/noticia/2011/10/morre-john-mc...
Ok, come on. Both here and on Wikipedia people are posting links to blog posts or minor news sites that supposedly "support" the claim. But these are clearly instigated by the original Wikipedia edit itself, so that they don't provide any additional proof.
They also provide no source, and they published after it was published here. Not reliable.
"Não há detalhes sobre a causa de sua morte" = "There are no details about the cause of death".
Still awaiting a better source. The Wikipedia entry asserting his death has been reversed at the time of this writing...
Yeah, i'm still waiting on a source too other than twitter
Sorry but, what is your source ?
McCarthy's wife died in 1977 in a climbing accident

http://www.mcjones.org/System_R/SQL_Reunion_95/sqlr95-Vera.h...

Very interesting. Off-topic thought, but...

"So she joined the group to climb Annapurna, and was part of the second team to attempt the summit. You go up in pairs, so you do pairwise summit attempts - these Himalayan style things where you do base camps. So she was working her way to the upper camp as the first summit team was coming down between the topmost and the second topmost. They passed, and then she was lost - she and her partner were lost. We're quite sure they fell. They were roped together; we think one fell and took the other with them."

As I was reading that I was thinking, 'why twos? that's not enough to anchor someone if they fall through an ice crevice or something, need at least three for that.' And then I get to the end, and that's exactly what happened. I wonder if people still attempt Himalayan mountains in twos like that.

Crevasses are normally encountered during glacier travel. These aren't particularly common on steep slopes.

Moreover, climbing as a trio tends to be (much) slower than traveling as a pair. When weather and hypoxia are your biggest threat, speed can literally be the only thing keeping you alive.

Death date removed from Wikipedia.

Latest edit shows:

"(Protected John McCarthy (computer scientist): Violations of the biographies of living persons policy: Rumors of his death added to page. May be true, but better to wait than edit war."

That was me. I saw the laughing squid link, followed it here, then discovered that their ultimate reference was the wikipedia article. I'm keeping tabs on the news so if an article pops up I'll add it or unprotect the article.
Death date now reinstated. (22:09 BST, 21:09 Zulu)
It [edit: the Brazilian article] cites Steven Levy, senior writer of Wired, as the source. It does not say where the source is found, but I assume it's this tweet:

http://twitter.com/#!/stevenjayl/status/128568370055491584

He may be a writer for Wired, but he doesn't seem to have a solid source either.

EDIT: There seems to be someone that claims Stanford has confirmed it by phone, as you can see in the Discussion page of Wikipedia, though:

"I spoke to the Associate Director of Communications at Stanford School of Engineering, and Dan Stober of Stanford News Service. Both have confirmed that Professor McCarthy passed away this weekend. They both said there were not a lot of details available at this time. An obituary will be issued by Stanford soon. http://chime.in/user/toybuilder/chime/65979187159736320 -- I apologize for bad formatting. I'm not a regular Wiki editor. Joseph Chiu 24 October 2011, 2:11 PDT. I have not edited the article page."

I reverted it again. I feel terrible doing that but the alternative is sourcing our article from personal communications or a tweet. Have yet to see a reference which is reliable (in the wikipedia sense) or not ultimately derived from the original edit to wikipedia.
If this is true may have to get CL or Racket set up tonight and do some coding in memory. Ungh what a crappy month for Computer Science.
Death always comes in threes.
I got a call this morning from his daughter that he has died this morning. Sorry to have him go.
What a supremely provincial comment.
Oh, yes. Terribly, terribly provincial.
I saw him speak a few times at AAAI conferences - few people, if any, contributed more to the field of AI.
You're absolutely right. He was a living legend.
Seems like October 2011 has taken the best of tech, each great in their own way... RIP John McCarthy
