Author here (Florian): I just fixed this. Very good catch. Off-by-one errors are hard indeed. :)

Where can I find a list of those papers? I just spent a minute trying to find something using Google but didn't manage to find anything

https://amturing.acm.org/alphabetical.cfm links to a page for each awardee, with a link to their lecture.

Thanks a lot! I totally overlooked the lecture links

This book has the first 20. I have read through the first 5 or so and highly recommend it. https://www.amazon.com/ACM-Turing-Award-Lectures-1966-1985/d...

Thanks! I might end up reading that
