     Arthur Miller (1915-2005) is universally recognized as one of the greatest dramatists of the

20th century. 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 l930s.

     Miller's most famous play, Death of a Salesman, is a powerful attack on the American system,

with its aggressive (有进取心的) way of doing business and its insistence on money and social

status as indicators of worth. In Willy Loman, the hero of the play, we see a man who has got into

trouble with his worth. Willy is "burnt out" and in the cruel world of business there is no room for

sentiment (多愁善感): 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. 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 enthusiastic 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.

     Miller died of heart failure at his home in Roxbury, Connecticut, on the evening of February

10, 2005, the 56th anniversary of the first performance of Death of a Salesman on Broadway.
