When a Salvation Army officer learns that her father, a wealthy armaments manufacturer, has donated lots of money to her organization, she resigns in disgust but eventually sees the truth of her father's reasoning that social iniquity derives from poverty; it is only through accumulating wealth and power that people can help each other.

George Bernard Shaw (1856–1950) is one of the world’s greatest literary figures. Born in Dublin, Ireland, he left school at fourteen and in 1876 went to London, where he began his literary career with a series of unsuccessful novels. In 1884 he became a founder of the Fabian Society, the famous British socialist organization. After becoming a reviewer and drama critic, he published a study of the Norwegian dramatist Henrik Ibsen in 1891 and became determined to create plays as he felt Ibsen did: to shake audiences out of their moral complacency and to attack social problems. However, Shaw was an irrepressible wit, and his plays are as entertaining as they are socially provocative. Basically shy, Shaw created a public persona for himself: G.B.S., a bearded eccentric, crusading social critic, antivivisectionist, language reformer, strict vegetarian, and renowned public speaker. The author of fifty-three plays, hundreds of essays, reviews, and letters, and several books, Shaw is best known for Widowers’ Houses, Mrs. Warren’s Profession, Arms and the Man, Caesar and Cleopatra, Man and Superman, Major Barbara, Pygmalion, Heartbreak House, and Saint Joan. He was awarded the Nobel Prize in Literature in 1925.
