Barry Blackwell’s comment on the interaction between Samuel Gershon and Gordon Johnson 

This is interesting because although it sounds trivial it calls into question Cade's cognitive abilities. If you look at his 1970 paper in Baltimore, you will see only 2 references to his own work, both in the same journal but 15 years apart. Yet the volume and page numbers are the same 1: 195. This seems highly unlikely. I am reluctant to make mountains out of a molehill but I wonder if he was, at the age of 58, already showing signs of an early dementia that might explain his giving a lecture on the wrong topic and forgetting to mention Trautner and Gershon?
