Things started out a bit rocky: His 1940 play, The Man Who Had All the Luck, garnered precisely the antithesis of its title, closing after just four performances and a stack of woeful reviews. Six years later, however, All My Sons achieved success on Broadway, and earned him his first Tony Award (best author). Working in the small studio that he built in Roxbury, Connecticut, Miller wrote the first act of Death of Salesman in less than a day. It opened on February 10, 1949 at the Morosco Theatre, and was adored by nearly everyone. Salesman won him the triple crown of theatrical artistry: the Pulitzer Prize, the New York Drama Critics' Circle Award and a Tony.
In 1956, Miller left his first wife, Mary Slattery. Shortly thereafter, he married famed actress Marilyn Monroe. Later that year, the House of Un-American Activities Committee refused to renew Miller's passport, and called him in to appear before the committee—his play, The Crucible, a dramatization of the Salem witch trials of 1692 and an allegory of McCarthyism, was the foremost reason for their strong-armed summons. However, Miller refused to comply with the committee's demands to "out" people who had been active in certain political activities.
In 1961, Monroe starred in The Misfits, a film for which Miller supplied the screenplay. Around the same time, Monroe and Miller divorced.
Within several months, Miller married Austrian-born photographer Inge Morath. The couple had two children, Rebecca and Daniel. Miller insisted that their son, Daniel, who was born with down syndrome, be completely excluded from the family's personal life. Miller's son-in-law, actor Daniel Day-Lewis, visited his wife's brother frequently, and eventually persuaded Miller to reunite with his adult son.
