His obituary dated 5 August 1961 read:
The death of Dr J Kempton, consultant paediatrician to the Reading Group of Hospitals, as a result of a tragic ocean-yachting disaster in the Bay of Biscay on July 12 has come as a shock to his colleagues and many friends in Britain and abroad. He was 52 years of age. Jack Kempton, the son of a schoolmaster, was born in Wales on December 31, 1908. He studied medicine at the University of Bristol, graduating MB ChB in 1932. After preliminary house appointments at the Bristol Royal Infirmary he decided to go into General Practice, and, after gaining experience as a locum tenet, settled in Wokingham, where he very quickly worked up a large practice. At the outbreak of the second world war he joined the RAMC, serving in England and the Middle East, and was eventually posted to Malta. On returning to civilian life he decided to set out on a consultant career in medicine and paediatrics, and it was to his great credit, and typical of his pertinacity, that he had no difficulty in obtaining the DCH, MD, and MRCP in 1946-47, while at the same time doing out-patient sessions at Paddington Green and Great Ormond Street Hospitals, where he was out-patient medical registrar. He was then appointed, first, a registrar, and then, in 1948, consultant in paediatrics to the Reading Group of hospitals. In addition to his Reading appointment he carried out regular visits to Taplow Hospital and attended out-patient sessions at Paddington Green and Great Ormond Street Hospitals. He was elected FRCP in 1958.
