Currently and for many years, one of the leading playwrights and directors of the New York stage, Moss Hart here tells, with considerable introspection and at times almost total recall, the story of his early years and the breaks that led to Broadway. Born of a crushingly poor family in the Bronx, early fired to a love of the theatre by the vagaries of an aunt with pitiful delusions of grandeur, sustained- through gruelling ears as ""social director"" in adult summer camps- by the desire to escape from his background through the medium of the theatre, Mr. Hart writes with much understanding of his family, and with devastating effect when he tackles dishonest or incompetent camp managers. The heart of the book tells in exhaustive detail the story of his first collaboration with George Kaufman on Once in a Lifetime and provides good long, and fascinating look at the machinery of hit-making, made the more palatable by the fact that this particular agony ended in triumph. Affecting and appealing this should create a waiting market for Act Two.
