Bernard Greenfield died within a few weeks of his 89th birthday after suffering from Alzheimer's disease since June 2001. He was born in Hackney and educated at the Central Foundation School, Cowper Street, EC2. He matriculated in 1931 and spent a year in the sixth form before leaving to work in a general engineering factory. The long journey made studying for a BSc impossible and he was persuaded to change to dental surgery by his local dentist. He studied for 1st MB at Chelsea Polytechnic and passed after two terms. He completed his dental studies at the National Dental Hospital in Great Portland Street, passing the LDSRCS examination in February 1939. He was commissioned into the RAF and served in North Africa, Sicily and India. After the war he practised in Hendon, Harley Street and Queen Anne Street. He went back to UCHDS to teach conservation, at the same time obtaining the BDS degree in 1949 and the FDSRCS in 1951. He had an enquiring mind that needed much intellectual stimulation and he found this in the Physiology Department of the Royal College of Surgeons where he developed a lasting interest in the electromyography of the muscles of mastication. Bernard was a very popular teacher, he was deeply devoted and loyal to the students and never had a bad word to say about anyone. As a colleague he was stimulating and provocative in discussions with a very subtle sense of humour. He was fiercely loyal to UCHDS and to the old National Dental Hospital. For relaxation Bernard enjoyed gardening, walking and camping. He shared these hobbies with his wife Shirley, and continued walking well into his later years. However his passion was work and on retirement from the Dental School in 1979 he continued as Honorary Research Fellow and was invited to continue his honorary work at the Eastman on the closure of UCHDS, until 1998. He first met his wife Shirley at the Royal College of Surgeons. She worked as his dental nurse for 35 years and after he became ill in 2001 she nursed him devotedly through two very difficult years until a urinary infection led to his death in hospital on 9 July 2003. We will remember Bernard as a very private, modest and unassuming gentleman who made a great contribution to dental science. He was much loved by his patients, his students and his many friends. He will be greatly missed by Shirley to whom our deepest sympathy is extended.
