Leonard Sidney Woolf was a British political theorist, author, publisher and civil servant, and husband of author Virginia Woolf.
Woolf was born in London, the third of ten children of Solomon Rees Sidney Woolf (known as Sidney Woolf), a barrister and Queen's Counsel, and Marie. His family was Jewish. After his father died in 1892 Woolf was sent to board at Arlington House School near Brighton, Sussex. From 1894 to 1899 he attended St Paul's School, and in 1899 he won a classical scholarship to Trinity College, Cambridge, where he was elected to the Cambridge Apostles. Other members included Lytton Strachey, John Maynard Keynes, G. E. Moore and E. M. Forster. Thoby Stephen, Virginia Stephen's brother, was friendly with the Apostles, though not a member himself. Woolf was awarded his BA in 1902, but stayed there for another year to study for the Civil Service examinations held then.
In October 1904 Woolf moved to Ceylon to become a cadet in the Ceylon Civil Service, in Jaffna and later Kandy, and by August 1908 was named an assistant government agent in the Southern Province, where he administered the District of Hambantota. Woolf returned to England in May 1911 for a year's leave. Instead, however, he resigned in early 1912 and that same year married Virginia Stephen.
Leonard and Virginia Woolf lived at 17 The Green Richmond starting from October 1914. In early March 1915 the couple moved to nearby Hogarth House, Paradise Road. In 1919, the Woolfs purchased the Round House in Pipe Passage, Lewes. The same year they discovered Monk’s House in nearby Rodmell, which both she and Leonard favored because of its orchard and garden. She then bought Monk’s House and sold the Round House.
Together Leonard and Virginia Woolf became influential in the Bloomsbury Group, which also included various other former Apostles. In December 1917 Woolf became one of the co-founders of the 1917 Club, which met in Gerrard Street, Soho.
After marriage, Woolf turned his hand to writing and in 1913 published his first novel, The Village in the Jungle, which is based on his years in Sri Lanka. A series of books followed at roughly two-yearly intervals.
On the introduction of conscription in 1916, during the First World War, Woolf was rejected for military service on medical grounds, and turned to politics and sociology. He joined the Labour Party and the Fabian Society, and became a regular contributor to the New Statesman. In 1916 he wrote International Government, proposing an international agency to enforce world peace.
As his wife's mental health worsened, Woolf devoted much of his time to caring for her (he himself suffered from depression). In 1917 the Woolf’s bought a small hand-operated printing press and with it they founded the Hogarth Press. Their first project was a pamphlet, hand-printed and bound by themselves. Within ten years the Press had become a full-scale publishing house, issuing Virginia's novels, Leonard's tracts and, among other works, the first edition of T.S. Eliot's The Waste Land. Woolf continued as the main director of the Press until his death. His wife suffered from severe bouts of mental illness throughout her life, until her suicide by drowning in 1941. Later Leonard fell in love with a married artist, Trekkie Parsons.
In 1919 Woolf became editor of the International Review. He also edited the international section of the Contemporary Review from 1920 to 1922. He was literary editor of The Nation and Atheneum, generally referred to simply as The Nation, from 1923 to 1930), and joint founder and editor of The Political Quarterly from 1931 to 1959), and for a time he served as secretary of the Labour Party's advisory committees on international and colonial questions.
In 1960 Woolf revisited Sri Lanka and was surprised at the warmth of the welcome he received, and even the fact that he was still remembered. Woolf accepted an honorary doctorate from the then-new University of Sussex in 1964 and in 1965 he was elected a Fellow of the Royal Society of Literature. He declined the offer of Companion of Honour in the Queen's Birthday honours list in 1966.
Woolf died on 14 August 1969 from a stroke.
