Fanny d’Arblay wrote of Strahan in 1798: ’He has all the appearance of a very worthy, sensible, unpretending man, well-bred and good natured’. He had ’inherited his father’s professional enimence, his political attachments, his consistency of public conduct and his private virtues’, according to an obituary. Like his father he purchased close borough seats in Parliament, but had no political ambitions. Writing to Lord Wellesley in 1810 in pursuit of the renewal of a contract to print the London Gazette awarded him by Canning as Foreign secretary, he referred to his ’unalterable attachment to his Majesty’s government’. In nearly 24 years at Westminster he is known to have contributed to debate only once, and then on the distribution of state papers, 19 May 1803. He was however of material assistance to the select committee on the promulgation of the statutes, 1796-7.
Strahan, who invested in East India Company stocks and subscribed £5,000 to the loyalty loan for 1797, is not known to have voted against Pitt’s or Addington’s administrations. He was listed ’Pitt’ in September 1804 and, after voting against the censure of Melville on 8 Apr., in July 1805. In May 1807 he obtained, for £4,500, a borough seat, placed by Lord Charleville at the disposal of the Irish government at the instigation of Charles Long.
The Treasury found another seat for Strahan in 1812, this time on the Crespigny interest. To their embarrassment he offered 6,000 guineas for it, obliging his colleagues to pay the same.
’Equally eminent for the correctness of his typography and the liberality of his dealings’, his modest way of life enabled him to act as patron to aspiring men of letters. He presented £1,000 each to the Literary Fund and to six other charities and £1,225 to the Stationers’ Company, of which he was a member. ’He acquired great literary property and influence in the learned world of purchasing the copyrights of the most celebrated authors of his time.’ At his death, 25 Aug. 1831, he left his nephews and successors, Andrew and Robert Spottiswoode, property valued at ’more than a million of money’.
