Editor and novelist
Having lived for a period at Oxford, where he spent more time visiting literary friends than studying, he dabbled briefly in the politics of the Labour movement, and in 1919 took up a post as literary editor of the socialist Daily Herald. He lived at 54 Tufton Street, Westminster from 1919 to 1925; the house is no longer standing, but the location of his former home is marked by a memorial plaque.
During his period at the Herald, Sassoon was responsible for employing several eminent names as reviewers, including E. M. Forster and Charlotte Mew, and commissioned original material from "names" like Arnold Bennett and Osbert Sitwell. His artistic interests extended to music. While at Oxford he was introduced to the young William Walton, to whom he became a friend and patron. Walton later dedicated his Portsmouth Point overture to Sassoon in recognition of his financial assistance and moral support.
Sassoon later embarked on a lecture tour of the USA, as well as travelling in Europe and throughout Britain. He acquired a car, a gift from the publisher Frankie Schuster, and became renowned among his friends for his lack of driving skill, but this did not prevent him making full use of the mobility it gave him.
Sassoon was a great admirer of the Welsh poet Henry Vaughan. On a visit to Wales in 1923, he paid a pilgrimage to Vaughan's grave at Llansantffraed, Powys, and there wrote one of his best-known peacetime poems, "At the Grave of Henry Vaughan". The deaths of three of his closest friends - Edmund Gosse, Thomas Hardy and Frankie Schuster (the publisher) - within a short space of time, came as another serious setback to his personal happiness.
At the same time, Sassoon was preparing to take a new direction. While in America, he had experimented with a novel. In 1928, he branched out into prose, with Memoirs of a Fox-Hunting Man, the anonymously-published first volume of a fictionalised autobiography, which was almost immediately accepted as a classic, bringing its author new fame as a humorous writer. The book won the 1928 James Tait Black Award for fiction. Sassoon followed it with Memoirs of an Infantry Officer (1930) and Sherston's Progress (1936). In later years, he revisited his youth and early manhood with three volumes of genuine autobiography, which were also widely acclaimed. These were The Old Century, The Weald of Youth and Siegfried's Journey.
