Edward Grenfell, 1st Baron St Just
Edward Charles Grenfell, 1st Baron St Just, was a British banker and politician.
His father, Henry Riversdale Grenfell, was Governor of the Bank of England between 1881 and 1883. William Grenfell, 1st Baron Desborough, was his first cousin.
He was educated at Harrow School and Trinity College, Cambridge, where he was secretary of the Pitt Club. On graduation, he immediately entered a career in banking with a position in Brown Shipley, and subsequently with Smith Ellison, moving to J. S. Morgan & Co. in 1900. In 1904 Grenfell became a partner in the bank and in 1910, when J. P. Morgan restructured his London bank, it was renamed Morgan, Grenfell & Co. to reflect his position as senior partner. He was a director of the Bank of England from 1905 to 1940.
Grenfell married Florence Emily Henderson in 1913. In May 1922 he was elected a Unionist Member of Parliament for the City of London in a by-election and held the seat until 1935, when he was raised to the peerage as Baron St Just, of St Just in Penwith in the County of Cornwall. Lord St Just died on 26 November 1941, aged 71, and was succeeded in the barony by his only child Peter George Grenfell.
