Sir Bruce Lyttelton Richmond (12 January 1871 – 1 October 1964) was a British editor and journalist who was the editor of the weekly literary review the Times Literary Supplement (TLS) for 35 years from a few months after its founding in 1902, to his retirement in 1937. His period of editorship is the longest to date, and during his time well over 1600 issues were produced with numerous reviews contributed by many literary figures. Richmond's obituary in The Times in 1964 described him as "The Architect of the Times Literary Supplement", while the authors of the introduction to the TLS Centenary Archive stated in 2001 that Richmond had "created and sustained one of the most durable of modern British institutions".
Richmond was born in Kensington, London on 12 January 1871. His maternal grandfather was Henry Bruce, 1st Baron Aberdare. He was educated at Winchester College and New College, Oxford. While at Oxford, he represented the university in two first-class cricket matches. He graduated from Oxford in 1894, and then studied law, being called to the bar in London (Inner Temple) in 1897.
In 1899, Richmond, at the request of the editor George Earle Buckle, became an assistant editor at The Times newspaper. In 1902, in addition to his existing editorial duties, Buckle appointed Richmond as editor of the Times Literary Supplement (TLS), a weekly literary review which at that time was a supplement to the parent newspaper. Richmond took over the editorship of the TLS from James Thursfield at a time when the TLS was only a few months old and when the publications were still owned by Arthur Fraser Walter. In 1908, ownership changed to Lord Northcliffe, who eventually forced Buckle's resignation in 1911. The new editor was George Geoffrey Dawson, and further change followed three years later in 1914 when the TLS became a separate publication. Richmond remained at the helm of the TLS and steered it through both these changes and later challenges.
