James Gregory was born in January 1753 in Aberdeen, the son of John Gregory, professor of medicine at Edinburgh University. He was educated at Aberdeen and Edinburgh, and studied for a short time at Christ Church, Oxford. During the winter of 1773-74 he studied at St George's Hospital, London. His father died suddenly in the winter of 1773 whilst he was still a medical student, and he completed his father's course of lectures at Edinburgh University. He did this with such success that his father's chair, the professorship of practice of medicine, was left open to Gregory. He graduated MD in 1774 and spent the following two years studying medicine abroad.
In 1776, at the age of 23, he was appointed professor at Edinburgh University. The following year he began giving clinical lectures at the Royal Infirmary. In 1780-82 he published his Conspectus Medicinae Theoreticae, which established his position in medicine. Although there was little original work in his Conspectus, it was valuable for what he wrote on therapeutics. In 1790 he succeeded to the chair of the practice of medicine at the university. From this point he was chief of the Edinburgh Medical School. Gregory attained a high reputation and had the leading consulting practice in Scotland, until his death. He was a friend of the poet Robert Burns.
He was widely popular as a teacher, particularly for his command of language, his excellent recollection of cases, his outspokenness, energy and humour. He was very practical in his approach, and advocated temperance, bodily exertion without fatigue, and mental occupation without anxiety, although he `by no means followed his own prescription' (DNB, 1890, p.100).
Gregory was a keen controversialist, and was keen-witted and sarcastic, but wasted his great powers on temporary and irritating controversies' (ibid). His controversy with the physician James Hamilton led to him severely beating Hamilton with a stick, for which he was fined £100 and costs for defamation. He then attacked, in his
Memorial to the Managers' of 1800, the practice of allowing all surgeons in Edinburgh to officiate at the Royal Infirmary in turn.
Gregory spoke out vehemently in opposition to the Edinburgh College of Physicians' recommendation to relax its regulations against the dispensing of medicines by members. The College charged him with violating his oath not to divulge its proceedings and having made false statements. He was found guilty by the College in September 1803, and was suspended from the rights and privileges of the fellowship in May 1809.
Gregory died on 2 April 1823, and was buried in Canongate churchyard, Edinburgh. Five sons and two daughters, by his second wife a Miss McLeod, survived him.
