I wish to declare a conflict of interest regarding the article on John Yudkin (JY). I am JY's son, and I was responsible for much of the article headed with his name, basing the article largely on the published material cited therein.
Together with a collaborator, I have just finished the draft of an article on JY's book "Pure, White and Deadly". My collaborator never worked with JY and had only one, casual, meeting with him. He believes he has no conflict of interest.
