A few words about Cameron Gordon

by Alan Reid

Camer­on and I both grew up in the North­east of Scot­land, the towns in ques­tion be­ing Lums­den and Buck­ie, re­spect­ively, and are ap­prox­im­ately 35 miles apart. Al­though Camer­on is older, I was at least aware of his fam­ily, since his fath­er had bakery stores: “Gor­don’s Bakery” in Lums­den and “The Strath­bo­gie Bakery” in Huntly, so I of­ten tell people I “knew of Camer­on’s buns be­fore I knew Camer­on”. In­deed, my par­ents also knew a fam­ily friend of Camer­on’s par­ents (John Boyd) from singing in a choir in the North­east of Scot­land.

So per­haps it was writ­ten in the Scot­tish sands that I would land in Aus­tin. Fun­nily enough, after I had just ac­cep­ted my first job at Ohio State in 1987, Camer­on called me (or rather called the phone num­ber of the De­part­ment of Math­em­at­ics in Ab­er­deen and the of­fice as­sist­ant came to get me), and asked if I would be in­ter­ested in a po­s­i­tion at UT. Thanks to Camer­on and John Luecke’s fin­an­cial sup­port I did end up vis­it­ing UT for a year in 1992–93. This made a huge im­pres­sion on me, both math­em­at­ic­ally and per­son­ally, and I de­cided if I could come back to UT it would be something I’d like to do.

I ar­rived as an As­sist­ant Pro­fess­or in 1996 and it is fair to say this was amongst the most pivotal mo­ments of my math­em­at­ic­al ca­reer. Simply put, be­ing in the de­part­ment with Camer­on (and oth­ers too many to name, but a spe­cial nod to John Luecke) demon­strated in the clearest pos­sible way to me what was needed for me de­vel­op as a math­em­atician.

Camer­on’s re­lent­less en­thu­si­asm for math­em­at­ics, both for ideas big and small, and his ab­so­lute at­ten­tion to de­tail and clar­ity of thought and writ­ing are hall­marks of how he works. His en­ergy, his per­son­al­ity and gen­er­os­ity, of both thought and fin­an­cial, all helped foster an in­clus­ive at­mo­sphere for fac­ulty, in­struct­ors and gradu­ate stu­dents alike to be part of the to­po­logy group at UT, and this left an in­delible im­pres­sion on all that were for­tu­nate enough to be part of this group.

I have writ­ten two pa­pers with Camer­on: the first is “Tangle de­com­pos­i­tions of tun­nel num­ber one knots and links” and the second (also joint with Dar­ren Long), “Sur­face sub­groups of Coxeter and Artin groups”. We also wrote one more (with João Nogueira, a former stu­dent of Camer­on’s) that re­mains stub­bornly un­fin­ished, al­though there does ap­pear to be some glim­mer of hope that it may get done soon! Without go­ing in­to the de­tails of these works, I can say work­ing with Camer­on up close was a priv­ilege, and I learned (and con­tin­ue to learn) so much from him whilst work­ing on these pa­pers. For ex­ample, I re­ceived “on the job train­ing” in the com­bin­at­or­i­al meth­ods of Gor­don and Luecke!

In 2011 I be­came chair of the de­part­ment at UT Aus­tin, and Camer­on was im­mensely help­ful, sup­port­ive, and al­ways a source of kind words and sage ad­vice. It was cer­tainly a huge re­lief to be able to chat with him when things were dif­fi­cult, and I al­ways felt grate­ful, and the bet­ter for do­ing so.

Let me close by say­ing that, some of my hap­pi­est memor­ies are be­ing in the de­part­ment with Camer­on (we were of­ten the only two fac­ulty in the de­part­ment on a Sat­urday/Sunday), or hanging out at Camer­on’s house (or my house) with Camer­on and Sue, my wife Mara, and usu­ally oth­ers quite of­ten Steve Boy­er on one of his now le­gendary “Boy­er breaks”) and en­joy­ing a few drinks in­to the wee hours. In fact I met Mara at a Hal­loween Party at Camer­on’s house in 1999, and fit­tingly Camer­on was dressed as Elvis. How can you not be in­spired by that! Thank you for everything Camer­on.

Alan Re­id re­ceived his PhD in 1988 from the Uni­versity of Ab­er­deen. After a num­ber of postdoc­tor­al po­s­i­tions in the UK and USA, he was ap­poin­ted as an As­sist­ant Pro­fess­or at UT Aus­tin in 1996 and re­mained on the fac­ulty at UT un­til 2017 when he joined the De­part­ment of Math­em­at­ics at Rice Uni­versity as the Edgar Odell Lovett Chair and Pro­fess­or of Math­em­at­ics. He is at present Chair of the de­part­ment.
