Eva Smith character description
Eva Smith is a sort of "everyman". Her first name "Eva" is similar to the first woman of the world (Eve) and is therefore symbolic of all women. Her second name "Smith" is an extremely common surname. It comes from the word for a tradesman. This shows that she is not an individual case, but rather an example of several other working class people who were terrorised by the carelessness of the higher classes.
Eva is a silent, offstage character. In the play, she represents the silent, invisible and powerless members of society. She dominates the action of the play invisibly.
The inspector speaks for Eva and uses her as a symbol of the powerless working class to teach the Birlings about social responsibility and to make them realise their mistakes.
The inspector says there are "millions of Eva Smiths and John Smiths still left" and their chances of happiness are "intertwined with our lives", making Eva Smith the central character.
The inspector tells the Birlings, and the audience, to behave responsibly towards other (Priestley's Message).
J.B Priestley uses her to make us think about our responsibility towards others.
