Cowper’s father, the connoisseur 3rd Earl, resided most of his life at Florence, being ‘the first Prince of the Holy Roman Empire in the Cowper family’
‘As I did not wish to be considered one of those Members whose mouths were to be hermetically sealed’, he informed his brother, ‘I determined to break the ice the first convenient opportunity’: his was ‘the first oratorical maidenhead lost this Parliament’. He spoke for about ten minutes in favour of the inquiry into naval abuses, 14 Dec. 1802, ‘with very little hesitation and without betraying any great symptoms of being in a funk’. Lady Melbourne assured Lord Cowper that the speech was received with
great encomiums from all parties; they say his manner was uncommonly pleasing and gentlemanlike, and the matter very sensible and well expressed. I wish I had not to add that he spoke with great approbation of the present ministry and concluded with promises of support; indeed this seems to have been his principal reason for speaking as there was no question before the House.
Fox reported, 1 Jan. 1803, ‘There have been two young speakers, Kinnaird and Lord Cowper’s brother, by what I hear the latter the most promising’.
Unless he was the ‘Mr Cooper’ who in a speech of 10 May 1803 was critical of the effects of long delays in the hearing of election petitions, Cowper did not again feature as an orator. He voted with the minority for inquiry into the Prince of Wales’s finances, 4 Mar. 1803. On 3 June he supported Pitt’s question for the orders of the day and on 8 Mar. 1804 was listed as one of Pitt’s friends who stayed away on the previous night’s divisions on the Irish government’s handling of Emmet’s rising.
Cowper was reported to be one of those Pittites disgruntled at their exclusion from the Grenville ministry in February 1806.
Cowper was not listed as a supporter of theirs by Liverpool’s government. He voted for Catholic relief throughout in 1813 and for Christian missions to India, 22 June 1813. (In 1806, as an East India Company stockholder, he was entitled to three votes for the directorate.) Afterwards he sank without trace, except for a grant of leave of absence for ill health, 22 May 1815. Early in 1817 he vacated his seat, letting in his ministerial opponent of 1812, Viscount Cranborne. He died at Nice, ‘where he had gone for the recovery of his health’, 1 Feb. 1823, He left a connoisseur’s collection of drawings and engravings.
