Thanks, Peter, for compiling this list, this is great! There were also "Kategorien" meetings at Oberwolfach in 1972 and 1973, organized by John Gray and Horst Schubert, which were probably instrumental in establishing the tradition of summer conferences in category theory: Oberwolfach, 23-29 July, 1972, Oberwolfach, 22-28 July, 1973. When leafing through the Oberwolfach archives (to recall the dates above), to my surprise, I saw that there was also a summer conference on "Kategorien und Funktoren" in 1966, organized by Albrecht Dold and Saunders Mac Lane(!): Oberwolfach, 17-23 July, 1966. This was just one year after the 1965 La Jolla meeting, probably to be considered the first major international conference on category theory ever. In Aveiro (CT2015) we acknowledged the 50th anniversary of that pivotal conference. With the help of all readers of the list (and perhaps by leafing through old Springer Lecture Notes), it should be possible to close the information gap in the open interval (1966,1972).

When the 100th PSSL meeting was held in Cambridge last year, I made public the (almost) complete list of speakers and titles of talks at PSSL meetings, which I've been keeping since they started. A number of people suggested that it would be interesting to have a similar list for the summer CT meetings. I'm afraid that compiling a full list of speakers at such meetings would be beyond my resources, but I thought it might be of interest to make a list of the dates and locations of the meetings. So here is my first attempt at compiling it; it's in the form of a plain TeX document, but should be easily readable as text. At present it begins with the first Isle of Thorns meeting in 1974, simply because that was the first such meeting that I attended; information on earlier meetings, and corrections to the information below, are very welcome.
