Emeritus professor of child health Liverpool (b 1909; q Liverpool 1933; MD, DCH, FRCP), d 5 December 2003.
John Hay was the first professor of child health in Liverpool. He pioneered the use of cardiac catheterisation in children and built up a team of skilled surgeons and anaesthetists. In 1948 he started the Alder Hey collection of babies' hearts taken at post mortem and by 1999 there were more than 2000 available for study. They undoubtedly played a major role in improving the care of children with heart abnormalities. Predeceased by his wife, Netta, he leaves three children and 12 grandchildren.
