Spens family who owned the estate of Lathallan in Fife. He was the son of Thomas Spens, 15th Laird of Lathallan and his wife Janet (née Douglas). He was admitted into the
Incorporation of Surgeons of Edinburgh on 24 July 1751. He obtained the degree of MD from the
University of St Andrews. After practising as a surgeon in Edinburgh, he increasingly became more interested in the practice of physic, becoming a Licentiate of the
Royal College of Physicians of Edinburgh in 1773 and fellow of that college the following year. He went on to become treasurer of the college and its
president in 1794. In 1773 he was elected a member of the
Aesculapian Club. On 12 April 1782 Spens was one of the founding members of the
Harveian Society of Edinburgh and served as President in 1789. He purchased in 1792, the estate of Craigsanquhar, in Fife which had once been part of the family estate of Lathallan, but had been sold in 1524. ==Archer==
