Carter came of a Portsmouth burgess family that had intermarried with well-to-do dissenting merchant stock there for the past century.
John Carter, the only surviving heir to this tradition, a delicate, accident-prone, studious child, whose one ambition was to be top of his class, went up to Cambridge, the first of the family to do so (he conformed). While he was there his father died, writing a benediction not long before his death (21 Mar. 1808): ‘I know that if you do not succeed to your wishes it makes you uneasy ... Various reasons may prevent your always succeeding—our abilities may not be the same at all times. I am sure it will not be for want of application.’
In October 1816 Carter was returned for Portsmouth unopposed on the death of Sir Thomas Miller. His election was a foregone conclusion; he simply had to decide whether he wanted the seat ‘at this early period of my professional career’ as he informed William Smith, who had become his father-in-law.
Carter, who had only £600 a year at his marriage plus £200 a year as a special pleader, lived in a house provided by his brother-in-law until in 1819 he was called to the bar, earned £750 a year and eventually gave up advocacy and £1,850 a year in 1826, when he inherited an estate worth £4,000 a year. He had practiced on the western circuit from the spring of 1819. Now he was able to devote himself to Parliament, but he scarcely ever spoke, ‘and when speaking on the hustings, at meetings, and elsewhere, he spoke tersely, and to the point, without hesitation, but in rather a curt and severe style, and without any attempt at oratory’. ‘A thorough man of business ... he required some constant object ... His conversation was always manly, sound and to the point. No one presided so well at table: he was never frivolous or loose, often playful and jocose ... always replete with sound information.’
Carter four times ‘resisted the temptation’ of office under the Whigs, and died a diabetic, 17 Feb. 1838, aged 49.
