Faber was the eldest son of Charles Wilson Faber, of Northaw, a Deputy Lieutenant of Hertfordshire and Mary Beckett, daughter of Sir Edmund Beckett, 4th Baronet, and thus sister of the 1st Baron Grimthorpe.
Faber was educated at Eton and Trinity College, Cambridge, and was a senior partner in Beckett's Bank, Leeds and York.
[3][2] On 29 December 1905 he was raised to the peerage as Baron Faber, of Butterwick in the County of Lincoln,[4] and thus did not stand for re-election in the January 1906 general election.
Faber died in Marylebone, London, on 17 September 1920, aged 73, and is buried in Brompton Cemetery.
The grave lies to the east side of the main north approach path and is visible only through a low tunnel in the shrubbery.
