Isidore Spiro served in two world wars. In the first world war he served as an ordinary infantryman in France. He was prevented from sitting the Final FRCS examination in 1939 because he had been called up, and when he eventually obtained leave from the British Expeditionary Force in order to sit he arrived too late because he was involved in the Dunkirk beaches evacuation. As a Major in the RAMC he was ophthalmologist at the Gibraltar Military Hospital. After being invalided out of the army in 1943 he joined the Admiralty Ferry Crew Association, and after the war he played a part in the repatriation of displaced persons by Luxemburg. He studied medicine at Liverpool University and University College Hospital, London, and immediately after qualifying began training as an eye surgeon first at Wolverhampton Eye Hospital and then as an assistant to Sir John Parsons at University College Hospital. After the war he became consultant ophthalmologist to Queen Mary's Hospital for the East End, Hillingdon Hospital and the Lister Hospital, Hitchin. He was active in establishing regional eye units in the North East Metropolitan Region, being secretary to the ophthalmic advisory committee in that region as well as being chairman of the corresponding committee in the North West Metropolitan Region. He was held in high esteem as a first class surgeon. He died on 7 January 1978 aged 79, survived by his wife.
