Son of the Rev Richard Green, sometime principal of Didsbury Wesleyan College, he was educated in London and received his early medical education in Birmingham. He went to Germany in 1891, first to Göttingen and afterwards to Heidelberg where he graduated MD. He then returned to Birmingham and was appointed surgeon to out-patients at the Queen's Hospital in 1897. He served as a civil surgeon during the South African War in 1900, but contracted enteric fever and was soon invalided home. He was surgeon to the Queen's Hospital, Birmingham, from 1906 to 1921, when he retired on account of ill-health and was elected consulting surgeon. From 1914 to 1924 he was professor of surgery in the University of Birmingham and during the war he was on the staff of the First Southern General Hospital, with the rank of major. He died at Trevone, Cornwall, on 29 November 1931, and was buried in the Shrewsbury General Cemetery. Leedham-Green was a man of commanding presence, who had complete confidence in himself. He was a very skilful operator and was especially interested in diseases of the genito-urinary organs and of the thyroid gland. He was a pioneer in the use of the cystoscope and in local and regional anaesthesia. After extensive experiment on various methods of sterilising the hands before operation he came to the conclusion that methylated spirit was best for the purpose. Quick in decision and impetuous in manner he could yet discuss and give reasons for the conclusions at which he arrived. As a teacher the students found him difficult to under-stand and were often unable to follow his line of thought.
