He was born in the manse at Sanquhar in south-west Scotland on 15 January 1847, the son of Janet and Rev. David Murray Croom of the United Presbyterian Church. The family moved to Edinburgh around 1855, where his father preached at the Lauriston Place church. In 1860, they were living at 1 Upper Gilmore Place in the Tollcross district. He attended the Royal High School in Edinburgh and studied medicine at the University of Edinburgh, graduating MD in 1868. He also studied in London and Paris. In 1870, he began lecturing in midwifery at Minto House on Chambers Street in Edinburgh and in 1878 became the Senior Lecturer. He became an assistant to Prof Thomas Laycock around 1880. In 1883 he became assistant gynaecologist at the Edinburgh Royal Infirmary. He ran the maternity wards from 1885 to 1900. His assistant from 1890 to 1894 was Dr James Lamond Lackie. A manuscript copy of lectures given by Croom and Lackie on midwifery and gynaecology taken down by a student survives as part of the Manchester Medical Manuscripts Collection, held by special collections at the University of Manchester. In 1886, he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Sir John Murray, John Batty Tuke, Sir William Turner and John Chiene. The latter is said to have been his lifelong friend. He was knighted for services to medicine in the 1902 Coronation Honours, receiving the accolade from King Edward VII at Buckingham Palace on 24 October that year. In the same year he was elected President of the Royal College of Surgeons of Edinburgh. From 1905 to 1921 he was Professor of Midwifery at the University of Edinburgh. In his later years he lived at 25 Charlotte Square one of Edinburgh’s most prestigious addresses. His friend John Chiene lived next door at 26 Charlotte Square. He died of congestion of the lungs at home in Edinburgh on 27 September 1923. He was buried in Dean Cemetery on Saturday 29 September. The grave lies towards the western end of the main east-west path, on its south side.
He married Anna Isabella Walker in 1875. She died in 1898. They had one son, Dr David Halliday Croom FRCPE and three daughters. David married Eleanor Addey Blair Cunynghame, daughter of the surgeon Robert James Blair Cunynghame. His eldest daughter had married Dr A J Beattie but happily also took on Croom’s domestic duties, so it was a double blow when she also died, in 1913. His brother was the civil engineer, James Murray Croom.
