He was educated at University College School and Hospital, winning an exhibition and gold medal in materia medica and pharmaceutical chemistry at the University of London intermediate examination. He was medical scholar of the Society of Apothecaries in 1885, and took first-class honours in medicine, surgery, and midwifery at the London MB examination. After studying the nervous system under Charlton Bastian at University College Hospital and the respiratory system at the Brompton Hospital under Douglas Powell, he was appointed assistant physician to the Victoria Hospital for Children, Chelsea, in 1889, becoming physician in 1897 and consulting physician in 1920. In 1893 he was appointed assistant physician to the Royal Free Hospital, ultimately becoming consulting physician and emeritus lecturer in medicine at the London School of Medicine for Women. During the four years' war he was physician to the hospital for officers in the Royal Free Hospital, and was created CBE for his services. He was an examiner at the Royal College of Physicians 1919-23 and also examined for the Conjoint Board, for the Society of Apothecaries, for Birmingham University, and for the State Register of Nurses. At the Royal College of Physicians he served on the council 1919-21 and as a Censor in 1926-27. He was president of the clinical section of the Royal Society of Medicine 1928-29, and president of the Medical Society of London in 1928, when he delivered the presidential address on "Medical ambitions and ideals", *Lancet*, 1928, 2, 753. He had previously addressed the Medical Society on "Life and problems in a medical utopia", *Lancet*, 1923, 1, 993. Walter Carr took the highest professional qualifications and was interested in every branch of pure medicine, though in later years his chief interest was in tuberculosis and diseases of the lungs. His most original contribution was made in his paper on "Non-tuberculous posterior basic meningitis in infants", in which he was the first to point out its relationship to cerebrospinal fever, as was subsequently confirmed. This was published in abstract only in *Proceedings of the Royal Medico-chirurgical Society, London*, 1897, 9, 110. Carr was a Freeman of the City of London and served in 1914 on the court of the Haberdashers' Company and as Master in 1929. He took an active interest in the Drapers' and Haberdashers' schools and served on the council of Epsom College. He was a strong walker both at home and in Switzerland. At the age of forty he was attacked by writer's cramp, and towards the end of his life was crippled by severe multiple arthritis. Carr married in 1895 Jessie, daughter of Walter Griffith of Streatham Hill. Mrs Carr died in 1937. He practised at 10 Cambridge Terrace and later at 10 Ferncroft Avenue, Hampstead, NW3, where he died on 29 September 1942, aged 80, survived by a son and three daughters, two of whom were married to medical men.
