John Luck was a urological surgeon in Windsor and Maidenhead. He was born on 26 February 1931, the son of Thomas Richard Luck, a manager, and Beatrice Christina Luck née McKenzie. He was educated at Southgate County Grammar School and then won an entrance scholarship to St Mary’s Hospital Medical School. He qualified in 1954 with two prizes in surgery and one in medicine. His first clinical post was as a house surgeon to Arthur Dickson Wright. He obtained his FRCS in 1959 and became a senior registrar at St Mary’s and gained a Fulbright scholarship as a surgical fellow to Harvard and the Peter Bent Brigham Hospital in Boston. There he became a renal transplant officer working on unrelated and cadaver renal transplantation. He also wrote three chapters on renal and bladder function for his professor, William Tait ‘Bill’ Irvine, as a contribution to *The scientific basis of surgery* (London, J&A Churchill, 1965) and several papers on renal transplantation. He then returned to St Mary’s, where he worked for Felix Eastcott. He was appointed as a consultant surgeon in Windsor with one session a week as a lecturer and honorary consultant at St Mary’s. He was initially a vascular and renal surgeon, but eventually specialised mainly in urology. He also continued his academic work, publishing further peer-reviewed papers and was co-author of General surgery in gynaecological practice (Oxford, Blackwell Scientific, 1971) with Stanley Simmons. He established a renowned urology practice in Windsor and Maidenhead. His talents included his clinical ability, his ability to diagnose and judge how to care for his patients and his considerable technical skills. He also retained the ability to teach and perform research. His many registrars obtained senior posts throughout the UK and internationally. His dissections were beautiful and achieved with apparent ease and sparseness of effort. He was patient, modest and never arrogant. He enjoyed cricket, tennis, golf, skiing, painting and drawing. Most of all, he had a very happy and fulfilling family life. Sadly, his first wife Heather (née Kerr) died of cancer in her fifties and he then married Carole (née Ranscombe), a consultant radiologist in Windsor. He had three children from his first marriage, a son from his second and two stepchildren. He died on 17 December 2019 at the age of 88. He was loved and respected by all and will be sadly missed.
