H.p. Pickerill, was a great man and did so much for NZ. Our soldiers and our children also training his wife Who did so much for NZ children (see A DAme We Knew, a tribute to Dame Cecily Pickerill) B Harris. Dr HPP your ideas are being reinvented as we speak.! Causes of Dental caries today, sounds like a new event! You were first and the best n NZ. As Swee Tan has said, without our pioneers where would we be now. Sorry you were left alone on your voyage to Australia but glad seven years later you found Cecily and You and she were so good together. Beryl. H
