Born on 24 May 1914, Walter was the first son of William Theophilus Wiggins-Davies, a manufacturing stationer in Birmingham. He was educated at King Edward School in Birmingham and at Trinity College, Cambridge, before his clinical studies at St Thomas's Hospital. He became a senior surgical registrar at St Thomas's and then first assistant in the urology department where he developed his interest and career in urology. He served in the RAMC with the rank of Major as a surgical specialist before his appointment as a consultant in urology to the Portsmouth Hospital Group. He was a senior Fellow of the Association of Surgeons and also of the Association of Urological Surgeons. He wrote articles on diseases of the prostate gland and bladder, urethroscopy, the treatment of urethral stricture, sling operations, and embryological studies about the persistent mesonephric duct. In 1941 he married Ann Gilbert but they were divorced and, in 1958, he married Cynthia Lee, who was also MRCS. They had one son who is a farmer. Walter was keen on shooting, fishing and bird-watching. His latter years were overshadowed by progressive respiratory deficiency which eventually confined him to the house and the use of oxygen.
