Born on Christmas Day 1728 at
Anjengo,
Travancore State, India, he was the second son of Alexander Orme, a physician and surgeon in the service of the East India Company. His mother's maiden name was Hill. He was sent when about two years old to the house of his aunt, Mrs. Robert Adams, in
Cavendish Square, London. From about 1734 to 1741 he was educated at
Harrow School under Dr James Cox, and was then placed for a year in the office of the accountant-general of the
Royal African Company. In 1742 Orme went to Calcutta, where his elder brother William was a
Writer in the East India Company. Orme engaged himself in the mercantile house of Jackson & Wedderburn at Calcutta, and made a voyage to
Surat. On returning to Calcutta in 1743 he was himself appointed a Writer in the East India Company's service. He acquired a reputation for knowledge of Indian customs, and in 1752 was asked to state his opinion on the regulation of the police in Calcutta. In 1753 he visited England, and during his absence in 1754 was appointed by the court of directors a member of the council at Madras. Returning to India, he arrived at Madras on 14 September 1754. He took an active part in the deliberations of the council respecting the military operations in the
Carnatic, 1754–8, and recommended the appointment of Clive to command the expedition against
Suráj-ud-Dowlah. Orme was for some years close to Clive, but the friendship was broken off about 1769. From 1757 to 1758 Orme was commissary and accountant-general. At the end of 1758, his health being poor, he left India with a small fortune. The
Grantham, the ship in which he sailed, was captured by the French on 4 January 1759 and taken to
Mauritius. Orme ultimately reached
Nantes in France in the spring of 1760. In the autumn of 1760 Orme bought a house in
Harley Street, London. He was elected fellow of the
Society of Antiquaries of London on 8 November 1770, and from about 1769 till his death was salaried historiographer to the East India Company. In 1792 Orme retired to
Great Ealing,
Middlesex, where he died on 13 January 1801, in his 73rd year. He was buried on 21 January in the churchyard of St. Mary's, Ealing where there was a memorial tablet. He was an admirer of
Samuel Johnson. ==Works==
