Richard you must have cheated by looking up the names on the internet, I had hoped that the answer would have resided in your memory! Ah well, you win. Next time I see you at a meeting I will bring your prize , a 16×20 inch mounted print of Comet Arend Roland taken by Reggie Waterfield in April 1957 (when you were still a boy) Yes you are correct. The Donohoe medal was awarded over 250 times by the ASP and there are so many famous names amongst the recipients.
