Sn rmoriam

SYDNEY JOSEPHS, M.D.,

SYDNEY JOSEPHS died suddenly on August 30 at the early age of 53 years. He graduated M.B., B.S. in 1941 at the University of Durham School of Medi- cine, and obtained the M.D. in 1949. After the usual house appointments he became a Surgical Registrar in the Teaching Hospital and later went to Bury Infirmary as a Resident Surgical Officer; this postgraduate training stood him in good stead as a radiologist.

Ill-health rendered him unacceptable for service with the Forces and in 1943 he decided to become a radiologist. In 1945 he passed the D.M.R. of Lon- don University. For a while he was a Junior Radio- logical Officer at Hammersmith before being appointed a Senior Registrar at the Newcastle General Hospital and he achieved consultant status in 1948 at the Newcastle General Hospital. Later he became the Senior Consultant in administrative charge of the Department of Radiology which is the largest and busiest in the region. He was very dex- terous in all the specialised radiological procedures but was particularly devoted to urology, obstetrics and cardiology. He was an early convert to the use of image amplification and closed-circuit television in urological and gastrointestinal investigations. Not only was he a well-informed and able radiologist but also a good doctor who was constantly consul- ted by his clinical colleagues.

In spite of several serious illnesses he seemed to

get down to work again with the same old zest and enthusiasm. He was never too busy to listen to the problems of his colleagues and patients and he endeared himself to all his associates. As head of a very busy department he was indefatigable in his efforts to secure the essential accommodation, equipment and staff to meet ever increasing de- mands. The Newcastle Regional Hospital Board appointed him as one of the Advisers in Radiology two years ago. His sympathetic ear and practical outlook appealed both to the administrators and to his radiological colleagues. Illness and busy daily routine did not prevent him from contributing to postgraduate medical education and at the time of his death he was engaged upon a research project with the University Departments of Paediatrics and Obstetrics.

Sydney Josephs was my colleague at the New- castle General Hospital and recently we worked together as Regional Advisers. He was everything that one could desire in a colleague, intensely loyal, kindly and full of sound common sense. His sudden untimely death is a severe blow tc the Newcastle General Hospital and Newcastle Region and many of us have lost a very good fliend as well as a colleague. He leaves a widow, two sons and one daughter, to whom our hearts go out at the sudden tragic loss of a beloved husband and devoted father.
