such sad and sudden (for me) news! I didn't know he was battling cancer. Phil was my maths supervisor when I arrived from Iran to Ottawa all those years ago. He helped me find my way around, introduced me to people, even got me an office and taught me how to use LaTex! It feels like he has always been around! We met at conferences and whenever he passed through where I was. Always nice, always supportive, and ready to explain a complicated piece of maths! Last time I saw him was in the Gandy memorial workshop at Wolfson college Oxford. ... will be enormously missed. ________________________________ From: Tom Leinster <Tom.Leinster@ed.ac.uk> Sent: Tuesday, December 19, 2023 5:08 PM To: Richard Blute <rblute@uottawa.ca>; Categories mailing list <categories@mq.edu.au> Subject: Re: Phil Scott ⚠ Caution: External sender Phil's passing is such sad news. I got to know him better during his visits to Edinburgh in recent years, and he was always so kind, gentle and encouraging - and humble too, despite all his achievements and accomplishments.

Been good friends with Phil ever since he called Jim at home and I picked up the phone, around 2000. Whenever in UK he always visited Oxford at the very least for a curry with us. The last time Phil was here, just before pandemic, was at my daughter's b'day dinner, at a curry house of course. ________________________________ From: Michael Barr, Prof. <barr.michael@mcgill.ca><mailto:barr.michael@mcgill.ca> Sent: 19 December 2023 15:48 To: Prakash Panangaden <prakash@cs.mcgill.ca><mailto:prakash@cs.mcgill.ca>; Richard Blute <rblute@uottawa.ca><mailto:rblute@uottawa.ca>; Categories mailing list <categories@mq.edu.au><mailto:categories@mq.edu.au> Subject: [EXT] Re: Phil Scott CAUTION: This email originated from outside of the organization.

I met him through Jim Lambek (he may have been Jim's postdoc) and then he went to Ottawa where I met him frequently. There was to have been a book titled Programs, Grammars, Arguments with Jim, Phil, and (maybe me), but I guess it will not happen. A version is available on my web.

Phil and Marcia have been friends for nearly 40 years. I was never a category theorist myself, but I did use it often in my work on theoretical computer science. Phil was my guide through and mentor. We had been out of touch for some years because of the pandemic, but we reconnected this year as were both having surgery at around the same time. I enjoyed his fun spirit and his insights into categorical logic and type theory. RIP Phil, we all miss you.

Phil’s many contributions to category theory are well known. Phil and Jim Lambek essentially invented the field of categorical proof theory with a series of papers that culminated in the book “Introduction To Higher-Order Categorical Logic”, which is still the standard text on the subject. Phil’s research went well beyond these initial works: he made major contributions to theoretical computer science, linear logic, inverse semigroup theory and recursion theory. Those of us who knew him personally will always think of him as a mentor, a friend and a genuinely kind soul.
