Born in London on January 30th, 1869, the son of Francis Wilson Lister and Elizabeth Wishart, only daughter of David Roy, of Glasgow. He was educated at the Haberdashers' Company's School, and received his professional training at Guy's Hospital, where he was House Surgeon in 1893-1894. He was Registrar and Pathologist to the East London Hospital for Children from 1897-1900, and from 1917-1919 Consulting Physician for Chest and Heart Cases to the Prince of Wales's Hospital for Officers, Marylebone. At the time of his death he was Physician to the Mount Vernon Consumption Hospital; Hon Advisory Physician to the Council of the National Association for Establishing Sanatoria for Workers, and had drafted, as chairman of its sites and buildings subcommittee, the scheme for the Benenden Sanatorium. He was also Physician to the Royal Waterloo Hospital for Children and Women, and to the City Dispensary; Consulting Physician to the Benevolent Fund of the National Union of Teachers, the National Association of Local Government Officers, and the Post Office Sanatorium Society. He was also an invited member of the Panel Committee of the County of London and of the Hospital Fund Board of Delegates, and Lecturer at the London School of Clinical Medicine. A man of many interests and of great industry, he carried out much valuable work. Possessed of a keen, incisive, mathematical mind, he interested himself deeply in the problems of life insurance and the industrial aspects of disease, especially of tuberculosis. He was a recognized authority on these subjects; indeed, one of the foremost, as his writings prove. He was the chief Medical Officer of three great life assurance offices - the Royal Exchange Assurance Corporation, the North British and Mercantile Insurance Office, and the Friends' Provident Institution. It was characteristic of him that he was not content to study the medical problems of life assurance only, but that he also endeavoured to get a grasp of the actuarial and the business aspects of this important subject. His Presidential Address before the Assurance Medical Society on March 3rd, 1920, was a thoughtful, original, and suggestive essay, indicating numerous lines for future investigation and research. In it he developed an ingenious idea of vital trajectories (curves). Lister died after a long illness at his residence at Henley-on-Thames on July 30th, 1924, being survived by his widow - only daughter of Eugen Ritter - two sons, and a daughter.
