A scion of a copper manufacturing dynasty who was later a distinguished City banker, the Liberal Grenfell made succinct, informed contributions in a number of areas during his brief parliamentary career. His family’s fortunes had been founded by his grandfather Pascoe Grenfell (1761-1838), of St. Just, Cornwall, a leading copper merchant and partner in a copper smelting business known after 1829 as Pascoe Grenfell & Sons, who had been one of the early industrialists to serve in the late Hanoverian Commons, representing Great Marlow, 1802-20, and Penryn, 1820-26.
Although Grenfell was a partner in the copper business, from the 1840s he pursued a career in the City in the family’s banking house.
Grenfell’s government connections meant that when he was invited to contest the Stoke by-election in September 1862, a rival Liberal candidate denounced him as a ‘placeman’, ‘nominee’ and a ‘creature of a Reform Club coterie’.
A Liberal loyalist, Grenfell supported the government’s redistribution of seats bill, 4 June 1866, although he admitted that it had been produced in a ‘hurry’. He challenged Robert Lowe’s defence of small boroughs as havens for young talented individuals, noting that few of these constituencies had recently returned MPs ‘who could be compared to Pitt, Fox, Burke or Canning’.
Grenfell unsuccessfully stood as William Gladstone’s running mate in South West Lancashire at the 1868 general election, and further attempts to return to the Commons at Truro in 1874 and Barnstaple in 1880 met with defeat.
