Arthur Miller is universally recognized as one of the greatest dramatists of the 20th century.(22)Miller’s father had moved to the USA from Austria, Hungary, drawn like so many others by the " Great American Dream". However, he experienced severe financial hardship when his family business was ruined in the Great Depression of the early 1930s.
     (23)Miller’s most famous play, Death of a Salesman, is a powerful attack on the American system, with its aggressive way of doing business and its insistence on money and social status as an index of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with this system. Willy is "burnt out" and in the cruel world of business there is no room for emotion: if he can’t do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success.(24)He refuses to face the fact that he has failed and kills himself in the end.
    When it was first staged in 1949, the play was greeted with good reviews, and it won the Tony Award for Best Play, the New York Drama Critics’ Circle Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards.(25)Miller died of heart failure at his home in Roxbury, Connecticut, on the evening of February 10, 2005.
