George Bernard Shaw (26 July 1856 – 2 November 1950) was an Irish playwright. Although his first profitable writing was music and literary criticism, in which capacity he wrote many highly articulate pieces of journalism, his main talent was for drama, and he wrote more than 60 plays. Nearly all his writings deal sternly with prevailing social problems, but have a vein of comedy to make their stark themes more palatable. Shaw examined education, marriage, religion, government, health care and class privilege.

He was most angered by what he perceived as the exploitation of the working class, and most of his writings censure that abuse. An ardent socialist, Shaw wrote many brochures and speeches for the Fabian Society. He became an accomplished orator in the furtherance of its causes, which included gaining equal rights for men and women, alleviating abuses of the working class, rescinding private ownership of productive land, and promoting healthy lifestyles. Shaw married Charlotte Payne-Townshend, a fellow Fabian, whom he survived. They settled in Ayot St. Lawrence in a house now called Shaw's Corner. Shaw died there, aged 94, from chronic problems exacerbated by injuries he incurred by falling. He is the first person to have been awarded both a Nobel Prize for Literature (1925) and an Oscar (1938), for his contributions to literature and for his work on the film Pygmalion (adaption of his play of the same name), respectively. Shaw wanted to refuse his Nobel Prize outright because he had no desire for public honors, but accepted it at his wife's behest: she considered it a tribute to Ireland. He did reject the monetary award, requesting it be used to finance translation of Swedish books to English.

George Bernard Shaw was born in Synge Street, Dublin in 1856 to George Carr Shaw (1814–85), an unsuccessful grain merchant and sometime civil servant, and Lucinda Elizabeth Shaw, née Gurly (1830–1913), a professional singer. He had two sisters, Lucinda Frances (1853–1920), a singer of musical comedy and light opera, and Elinor Agnes (1855–76). Shaw briefly attended the Wesleyan Connexional School, a grammar school operated by the Methodist New Connexion, before moving to a private school near Dalkey and then transferring to Dublin's Central Model School. He ended his formal education at the Dublin English Scientific and Commercial Day School. He harbored a lifelong animosity toward schools and teachers, saying: "Schools and schoolmasters, as we have them today, are not popular as places of education and teachers, but rather prisons and turnkeys in which children are kept to prevent them disturbing and chaperoning their parents". In the astringent prologue to Cashel Byron's Profession young Byron's educational experience is a fictionalized description of Shaw's own schooldays. Later, he painstakingly detailed the reasons for his aversion to formal education in his Treatise on Parents and Children. In brief, he considered the standardized curricula useless, deadening to the spirit and stifling to the intellect. He particularly deplored the use of corporal punishment, which was prevalent in his time.

When his mother left home and followed her voice teacher, George Vandeleur Lee, to London, Shaw was almost sixteen years old. His sisters accompanied their mother but Shaw remained in Dublin with his father, first as a reluctant pupil, then as a clerk in an estate office. He worked efficiently, albeit discontentedly, for several years. In 1876, Shaw joined his mother's London household. She, Vandeleur Lee, and his sister Lucy, provided him with a pound a week while he frequented public libraries and the British Museum reading room where he studied earnestly and began writing novels. He earned his allowance by ghostwriting Vandeleur Lee's music column, which appeared in the London Hornet. His novels were rejected, however, so his literary earnings remained negligible until 1885, when he became self-supporting as a critic of the arts.

Influenced by his reading, he became a dedicated Socialist and a charter member of the Fabian Society, a middle class organization established in 1884 to promote the gradual spread of socialism by peaceful means. In the course of his political activities he met Charlotte Payne-Townshend, an Irish heiress and fellow Fabian; they married in 1898. In 1906 the Shaws moved into a house, now called Shaw's Corner, in Ayot St. Lawrence, a small village in Hertfordshire; it was to be their home for the remainder of their lives, although they also maintained a residence at 29 Fitzroy Square in London.

Shaw's plays were first performed in the 1890s. By the end of the decade he was an established playwright. He wrote sixty-three plays and his output as novelist, critic, pamphleteer, essayist and private correspondent was prodigious. He is known to have written more than 250,000 letters. Along with Fabian Society members Sidney Webb and Beatrice Webb and Graham Wallas, Shaw founded the London School of Economics and Political Science in 1895 with funding provided by private philanthropy, including a bequest of £20,000 from Henry Hunt Hutchinson to the Fabian Society. One of the libraries at the LSE is named in Shaw's honor; it contains collections of his papers and photographs.

During his latter years, Shaw enjoyed attending to the grounds at Shaw's Corner. He died at the age of 94, of renal failure precipitated by injuries incurred by falling while pruning a tree. His ashes, mixed with those of his wife, were scattered along footpaths and around the statue of Saint Joan in their garden.
