My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Katrina Honigs meets Grothendieck

Posted by John Baez

Here’s a fun story by Katrina Honigs about how she found Grothendieck’s house in the Pyrenees, jumped the fence, knocked on the door, and offered him some pastries.

At some points it reads like a nightmare:

When he seemed totally unmoved by my getting out the bakery box from my bag and told me again to leave, I returned to the gate. I explained that I had climbed the gate to get in, but when he didn’t react at all, I thought (nonsensically, I now realize) that he wanted me to climb back over the gate to prove to him that this was indeed how I entered his yard. But, the ground under the gate was sloped so that the fence was significantly higher from the inside, and I was shaking from the huge influx of adrenaline that I was experiencing. After a few horribly embarrassing failed attempts at pushing myself back over the gate, during which all I could think, over and over, was “Alexander Grothendieck is watching me” (which he was, with what I might describe, in retrospect, as detached bemusement), I asked him to unlock the gate. However, he stood totally still and silent, like my own personal Ghost of Christmas Future, and then told me, once more, to get out.

No mathematics was discussed. However, it ends well.

It may be of interest to note that an abridged version of Honigs’ account had appeared in the March 2016 issue of the Notices of the AMS.

Re: Katrina Honigs meets Grothendieck

Am I alone in finding this story kind of unsettling? I am glad that the incident seems to have turned out comparatively well, but surely not curiosity, nor burnout, nor an urge to “demystify” can justify this urge to intrusion into anyone’s life, let alone someone who so determinedly communicated his desire for privacy as Grothendieck. Even granted that the author didn’t know that Grothendieck had explicitly denied her requests to visit, surely lack of denial cannot be regarded as permission?

I don’t mean this as an attack on the author—who among us has not done something as a graduate student that now seems kind of ill advised (no pun intended)?—but rather as a suggestion that perhaps this story shouldn’t have been told publicly, or have got the wide currency that a Notices publication gives it. On the other hand, I know Grothendieck even less than the author does, so perhaps I am off base.

Re: Katrina Honigs meets Grothendieck

I once heard an oral account by a graduate student who had also gone to Lasserre to find Grothendieck. His encounter was less successful, not resulting in any meaningful interaction. His motivations were to me opaque, but the psychology behind it seemed not different from that of those who ask basketball players for autographs and photos.

L Spice:

No. I agree that it’s obnoxious to chase after people who have deliberately done their damnedest to get away from us. But now that Grothendieck is dead, presumably this article will not cause any more people to pester him: the damage is done, so we might as well at least hear the story.

(If my theory of what happens at death are seriously mistaken, all bets are off.)
