Factual errors which have been pointed out by Gerald Wiener:Part 1 (c.25 mins in): “John Gibson” should be DAVID Gibson (“John” was Clair Taylor’s colleague, he eventually went to Guelph in Canada) approx. 43.32 –45.50 min of CD: I was reminded at this point that Mr White the caretaker at “Glenbourne” wanted to chase me off the premises when I came to look at my future place of employment - with him not knowing that I was not an intruder (showing how good a caretaker he was). Instead I launched again into why I was not taking up my appointment with “NABGRO” until September because I was earning more money elsewhere – and I never got back to the punch line. Part 2 (c.12.00 min in): “Cuthbertson” and then “Sir David Cuthbertson” should have been “PROFESSOR E. J. UNDERWOOD” (Underwood was the “doyen” in this field and chair of the Symposium. Cuthbertson, a very important man and former Director of the Rowett Research Institute – then in Glasgow – was President of the Symposium but NOT the chairman who, in the closing address, singled out my paper with Alex Field on the “genetic variation in copper metabolism in sheep”).
