The son of Benjamin North, of Woodstock, and Mary, daughter of Bartholomew Churchill, of Todmorden. He began his professional career as Assistant Surgeon in the Oxfordshire Militia. This was at the close of the Peninsular War, and when stationed at Bristol he had charge of a large number of recruits and French prisoners. After two or three years he left the Army and began to practise in London, becoming in time well known as a specialist in midwifery and the diseases of women and children. Later he was appointed Lecturer in these subjects at the Westminster Hospital School, and then at the Middlesex Hospital, where he succeeded Dr Sweatman in 1838. His lectures were remarkable for careful preparation, lucidity, and often eloquence of expression, as well as for the practical advice they contained. He married: (1) Miss Lyster, of Dublin, and (2) Miss Karie, of London who survived him. He died on March 6th, 1873, after his retirement, at his residence, 9A Gloucester Place, W.
