He was the illegitimate son of Levi the Jew, well known in the City and on the Exchange. His father had given Mr Thompson an excellent education; his genius was sprightly; and his taste in the arts, refined: but he was to be classed rather among the belle-lettres, than the well-informed men; for though he knew a little of most things, he was profound in none. Plunged, unhappily, in early manhood, into the vortex of fashionable dissipation, the most precious period of his life had been wasted in worse than idleness: and he had to lament, and frequently did he lament, that the only ‘wages’ he had earned from a wild course of lavish expenditure, were an injured fortune, and a broken constitution. The munificence of his father to him, had been princely: but, it could not keep pace with his extravagance; for play was one among the many modes, by which he ruined his finances ... He had seen and deplored his error, ere I became acquainted with him: and, I believe, nothing would have tempted him, to have touched again a card or a die. From the period of this loss, he devoted himself, as far as his shattered health would allow, to some of the higher species of literature.
This was the account of Thompson given by Rev. Richard Warner, who added that he was the illustrator of Pennant’s London. The ‘John Thompson’ described as his father on his admission to Cambridge and Lincoln’s Inn was ‘deceased’ by 29 Dec. 1785.
Thompson’s finances can scarcely have been helped by his parliamentary venture. In 1790, at the instigation of the Whig election managers, he successfully contested Evesham, retaining his seat after another contest in 1796, though he appears to have contemplated retiring then.
Thompson’s attendance fell off in the Parliament of 1796, after his appearance in the minorities of 8 and 30 Dec. 1796. He was a defaulter on 3 Apr. 1797 and absent ill on Grey’s reform motion, 26 May. He had been a steward for the reform meeting at the Crown and Anchor on 18 May.
On 25 Jan. 1802 Thompson wrote to a friend from Orléans that he had come abroad for health reasons, intending to winter at Nice, but had decided to stay where he was. By March it was known that he would not contest Evesham at the general election.
I trust your lordship will pardon my zeal to serve a particular friend for whom I feel most warmly interested, Mr Thomas Thompson, lately returned from France after having been detained by Bonaparte during the whole of the last war. His conduct to his countrymen who passed as prisoners from Spain thro’ Orléans (where he resided) is the subject of general admiration ... his knowledge of the language, character and intrigues of that nation fully qualifies him for the office of superintendent of aliens ... [he is] a perfect man of business ... it was with the passport of Mr Thompson that Col. Jenkinson was enabled to quit Paris with dispatches (announcing Bonaparte’s arrival) when orders were given to refuse leave to all attached to the Embassy.
Sidmouth mss.
Thompson died at Kensington Gravel Pits, 29 July 1818. Administration of his effects, valued below £1,000, was granted on 23 Sept. to Martha his widow, formerly of Portsea, lately of Newcastle-upon-Tyne.
