Alan Moncrieff
Sir Alan Aird Moncrief (9 October 1901, Bournemouth – 24 July 1971) was a British born paediatrician and professor emeritus at University of London. He was most notable for developing the first premature-baby unit in 1947. It was Moncrief who recognized and developed the concept of daily parental visits to the ward, which he developed while at Great Ormond Street, well before the need for this became recognised, and with his ward sister, published an article on Hospital Visiting for Children in 1949.
