Born in Tavistock Place, London, on Jan. 1st, 1811, the son of Daniel Curling, F.S.A., Secretary to the Commissioners of His Majesty's Customs, and Elizabeth, daughter of William Blizard and sister of Sir William Blizard. He was educated at The Manor House, Chiswick, and was afterwards apprenticed to his uncle Sir William Blizard (1743-1835), Surgeon to the London Hospital. During his apprenticeship he was a student at the London Hospital and attended the lectures of Edward Stanley (q.v.) and Sir William Lawrence (q.v.) at St. Bartholomew's Hospital, where Blizard, his master, had himself been educated. Curling began to write before he was qualified, and communicated an article on the cranium to Partington's *Cyclopoedia*, and another, on cases he had observed at the London Hospital, to the Hospital Reports in the *London Medical Gazette*. Sir William Blizard resigned his office of Surgeon to the London Hospital in 1833, James Luke (q.v.) was promoted, and Curling was elected Assistant Surgeon in January 1834, after a severe contest with William Coulson (q.v.). In the same year he gained the Jacksonian Prize at the Royal College of Surgeons for his essay "On Tetanus", which was published in 1836. About a year after his election Curling was required to reside in the immediate neighbourhood of the hospital, and for seven years he occupied a place called 'The Mount', in the Whitechapel Road, a name given, it is said, because of the accumulated rubbish carted there after the Great Fire of London. He devoted much time to surgical pathology whilst acting as Assistant Surgeon, made the post-mortem examinations, and lectured on morbid anatomy. In 1841 he was appointed, in conjunction with James Luke, Lecturer on Surgery at the London Hospital, and in 1849 was appointed Surgeon in the place of John Goldwyer Andrews (q.v.). He was admitted a F.R.S. on June 6th, 1850, and bequeathed at his death the sum of £200 to the Scientific Relief Fund of the Royal Society. Curling was Consulting Surgeon to the Jewish, to the German, and to the Portugese Hosptials: he was also Consulting Surgeon to the London Orphan Asylum and a member of the Medical Board of the Royal Sea-Bathing Hospital at Margate, in the affairs of which he took an active interest. At the Royal Medico-Chirurgical Society he filled the office of Surgical Secretary in 1845-1846 and President in 1871-1872. At the Royal College of Surgeons he was a Member of Council from 1864-1880, a Member of the Court of Examiners from 1871-1879, Chairman of the Midwifery Board in 1872, Vice-President in 1871 and 1872, and President in 1873. He discovered during his long tenure of office in the out-patient room of the London Hospital that the diagnosis and treatment of diseases of the testicle needed revision. He published a paper in 1841, "Some Observations on the Stucture of the Gubernaculum and the Descent of the Testis in the Foetus", and in 1843, *A Practical Treatise on the Diseases of Testicle, Spermatic Cord, and Scrotum. *The book met with a hearty reception, ran through many editions, and was translated into foreign languages, the Chinese version being made by Sir Patrick Manson in 1866. Curling published in 1851 *Observations on the Diseases of the Rectum*, which also had a large sale, and, like "Curling on the Testis", became a standard work. His paper at the Royal Medico-Chirurgical Society seems to have been the first to draw attention to the occurrence of duodenal ulcer after burns of the skin. He died at Cannes on March 4th, 1888. Curling's punctuality at the London Hospital was proverbial; he entered the gates as the clock struck the hour. In the wards he was exact and conscientious to a degree, his strong sense of duty to the patient leading him into the minutest supervision of the dresser's work. His sound judgement was grounded on vast clinical experience; he was consequently opposed to fanciful inductions. "His practice and his teaching were not at variance; both were sound, upright, and just." He was not personally popular, for his manner was cold, yet he was a staunch and sincere friend, whom to know was to trust and to honour. He was punctual in the performance of his duty in a remarkable way. He was not a good speaker, and instructed his pupils rather by what he did than by what he said. They could readily perceive that Curling's treatment of his patients was guided by fixed princicples, and that they could gain from him much valuable information. He was a careful and cautious operator, whose first consideration was a regard for the good of the individual patient. At the College he enjoyed the complete confidence of his colleagues on account of his zeal and the great interest he took in his work. The estimation in which his judgement was held by his contemporaries was shown by the fact that he was appointed five times to the important post of Surgical Referee at the Royal Medico-Chirurgical Society, the last time succeeding the period of his Presidency. Curling was a man of commanding stature. There is an engraving of him from a daguerrotype in the *Medical Circular*, a photograph in the Fellows' Album, and another in *Photographs of Eminent Medical Men* (Barker and Edwards, 1867, i), and there is an engraving in the possession of the London Hospital. In later life he is described as a gentleman, tall, erect with white hair, pale complexion, and an inheritor of the large nose which marked the Blizard family.
