James Hamilton, 7th Earl of Abercorn
James Hamilton, 7th Earl of Abercorn FRS PC (22 March 1686 – 11 January 1744), styled Lord Paisley from 1701 to 1734, was a Scottish and Irish nobleman and peer. An amateur scientist and musician, he published a book on magnetism in 1729 and a treatise on musical harmony in 1730, which was subsequently emended and re-issued by his teacher, Dr. Pepusch.
Hamilton was born on 22 March 1686 to James Hamilton and his wife Elizabeth Reading. His elder brother Robert was baptized on 12 July 1687 but died shortly afterwards, making James the heir apparent, with the style of "Lord Paisley", when his father succeeded as 6th Earl of Abercorn in 1701.
A scientist, Hamilton became a Fellow of the Royal Society on 10 November 1715, and published Calculations and Tables on the Attractive Power of Lodestones, a book on magnetism, in 1729. Lord Paisley also studied music under Johann Christoph Pepusch, and in 1730 published "A Short Treatise on Harmony", apparently without Pepusch's assent, and handling the subject in such a manner as to injure his reputation. However, the breach between them was apparently mended, as Pepusch paid a congenial visit to Paisley at his seat in Witham, Essex in 1733, and recovered his reputation by publishing a new edition of the treatise, revised and improved.
Hamilton succeeded as 7th Earl of Abercorn at his father's death in 1734. He was sworn a Privy Counsellor in Great Britain on 20 July 1738 and a Privy Counsellor in Ireland on 26 September 1739. On 17 October of that same year, George II issued a royal charter to the nation's first orphanage for abandoned children, the Foundling Hospital, of which Abercorn was a founding Governor.
