David Cornelius Morley was born on 15 June 1923 in Rothwell, Northamptonshire in the UK. He was the youngest of seven children born to a vicar and his wife. He attended school at Haywards Heath and then Marlborough College. Morley read Natural Sciences at Clare College, Cambridge and completed his undergraduate education at St Thomas's Hospital, from where he qualified in medicine in 1947. He then undertook military service in Singapore.
Professional career
In 1951 Morley took a junior hospital post in Sunderland, and then in 1953 moved to Newcastle where he worked with James Spence and Donald Court. Then in 1956 Morley moved to Ilesha, Nigeria, where he took up a research post at a Methodist hospital and first became interested in measles and growth monitoring. In 1973 he wrote of Nigeria "Three-quarters of our population are rural, yet three-quarters of our medical resources are spent in the towns where three-quarters of our doctors live; three-quarters of the people die from diseases which could be prevented at low cost, and yet three-quarters of medical budgets are spent on curative services." He found that low-cost healthcare initiatives within the community were more effective in treating infant mortality than hospital treatment, work that has influenced governments and agencies globally. In 1961, Morley returned to the UK and took up a post at the London School of Hygiene & Tropical Medicine, and then in 1964 moved to the Institute of Child Health where he set up the Tropical Child Health Unit, the World Health Organization/UNICEF course for senior teachers of child health, and diploma and masters' courses in mother and child health and disability studies.
Innovations
Morley developed, or was instrumental in the development of, many innovations and technologies in child healthcare. A double-ended plastic spoon allowed mothers to accurately measure the correct proportions of salt and sugar to treat dehydration successfully using oral rehydration therapy. While working in Nigeria he developed the "Road to health" chart, a parent-held growth chart for monitoring a child's weight to detect early signs of malnutrition. The concept of parent-held growth charts has now been copied globally. Facing the problem that innumerate mothers could not write down the weights of their children, he devised a mechanism attached to scales that could mark the weight directly onto a chart. Morley started the earliest trials of the measles vaccine, in which he included his own children. He also devised an asthma inhaler made from old plastic drink bottles, and a simple Mid-upper arm circumferencemeasuring tape for detecting severe malnutrition. Another of his innovations was sterilising water by placing it in sunlight. He instigated a series of trachoma reduction programmes in partnership with ICROSS, developing a fly trap to reduce the primary cause of trachoma transmission. Morley also identified the need for a low-cost device to measure a baby's temperature, and asked John Zeal to create one. The result was the ThermoSpot, a small disc that shows a green smiley face when the temperature is in the correct range.
Charity Work
In 1965 he established the charity Teaching-aids at Low Cost, a charity formed to provide healthcare books and other materials cheaply to healthcare workers and others in developing countries. TALC has sent over half a million books and other items overseas. He was closely involved with innovative research together with Dr Michael Elmore-Meegan of ICROSS with whom he published a series of studies. Then in 1978, with Hugh Hawes, he started Child-to-Child, an international network promoting children's participation in their own health and development, now the Child to Child Trust. He continued supporting ICROSS in Kenya and Tanzania until his death.
