Returned to the Commons as a Conservative on no fewer than thirteen occasions, Mowbray was a dedicated parliamentarian. Though he addressed the House only occasionally – at most half-a-dozen times a year – he was very conscientious in his attendance, sitting through hundreds of hours of debates each session. A committee man, who often quoted the advice of Sir Robert Peel, ‘Stick to committees’,
Though Mowbray was a very rich man, having married into considerable wealth and assumed the name of his father-in-law George Isaac Mowbray by royal licence in 1847, his own origins were less elevated. He was born John Cornish, the only son of a rising Exeter architect and builder, who in 1852-3 became mayor of his city.
From Westminster Mowbray went up to Christ Church, Oxford, obtaining a second class BA in 1837 and an MA in 1839. Strongly attached to Oxford, he would regularly return, and later in life, when he was an MP for the University, secured a number of honorary academic conferments. As president of the Oxford Union in 1836, Mowbray admitted spending more of his time debating than studying; he told his mother that he was regarded as ‘a promising speaker’.
When the corn laws were repealed in 1846, Mowbray had believed that ‘the game was up’ and remained loyal to Peel; he returned to Oxford in 1847 and 1852 to actively support Gladstone against protectionist candidates in the representation of the University.
It was usually on ecclesiastical or university matters that Mowbray contributed to debate. He began well: his objection to the treatment of the University of Durham under the provisions of the charitable trusts bill was upheld, 8 Aug. 1853. ‘I came home at 4am not a little elated’, Mowbray informed his wife, ‘because it was good fun to beat the ministers, who had behaved in a mean, shabby way, and it will be a feather in my cap at Durham’.
Mowbray expressed clear opinions about the leading statesmen of the 1850s and 1860s. He might have profoundly disagreed with John Bright, but he admired the speeches he made during the Crimean War. He liked Palmerston, but did not consider him much of a debater and, in February 1858, worried that ‘a radical Reform Bill … is just the course such a reckless gamester as Pam is likely to adopt’.
Out of office after Palmerston’s accession to office in June 1859, Mowbray remained busy, often chairing committees on private bills. He found this work very congenial; never a factional politician, he enjoyed working with MPs of whatever political hue (later in his career having cordial relations with Labour members). Not that he always got his own way: at one committee meeting for the qualifications for office bill in March 1865, ‘Bright entered the room late … &, with a few telling interrogatives, to which no consistent or tenable reply was forthcoming, reduced Mowbray to absolute silence’.
Only in 1853 had Mowbray faced a contest at Durham; at every subsequent election he was returned unopposed. In 1868, however, his connection with Durham came to an end. At the general election of that year he was returned, after the Liberal politician Sir Roundell Palmer had withdrawn, as one of the MPs for the University of Oxford, alongside his old friend Gathorne Hardy. The bells of Christ Church rang out to celebrate his return, apparently, Mowbray was informed, as they had for Sir Robert Inglis, the famed ultra-Tory MP for the University, 1829-54.
Mowbray remained in the House until his death. He was, to use his own phrase, ‘a thorough House of Commons man’
