Peel trained for the medical profession in England and had some experience as ship's surgeon on immigrant ships. Around 1865 he was recommended by Colonial Surgeon Dr.
R. W. Moore to a vacancy as house surgeon at the
Adelaide Hospital. In 1866 he was appointed Assistant Colonial Surgeon in charge of the
Mount Gambier district. While there where he was involved in local affairs: he was active in the formation of the Mount Gambier Institute, to which body he later donated specimens and curios collected in the Northern Territory, and was a Past Master of the Mount Gambier Lodge of Freemasons. In 1868, a year or so prior to the long-awaited opening of the Mount Gambier Hospital, he accepted an invitation to join
George Goyder's surveying expedition to
Darwin, Northern Territory, which left Port Adelaide on the
Moonta around 26 December 1868. Peel's successor at Mount Gambier was Dr. James Jackson MD. On his return to Adelaide on the barque
Kohinoor in April 1870, he started practising on his own account, with a surgery on
North Terrace, partly in conjunction with Dr. Thomas Cawley, with whom he shared an interest in thoroughbred racing. Dr. Peel served as surgeon to the racing clubs, and was a committeeman of the Licensed Victuallers' Racing Club, which afterwards amalgamated with the
Adelaide Racing Club. In 1880, following a journey to England, he joined in partnership with Dr. Beaney of
Collins Street, Melbourne. Around 1891 he returned to Adelaide, where on 26 June 1891 Peel was a passenger on the Hindmarsh tram, when he was thrown off after the tram jumped the points, landing on his back. His injuries were judged as slight, but he never recovered his accustomed fitness, and four years later died suddenly in a fit at the General Havelock Hotel. His remains were buried in the
West Terrace Cemetery. Among the small group of mourners were Dr. Cawley, also
S. King and
J. Le M. F. Roberts, fellow members of the Goyder expedition. He had no relatives in Australia; a brother, who predeceased him, was a physician at the Children's Hospital,
Dublin. ==Recognition==
