Arthur Miller was first considered a success as a writer with his play "All My Sons" in 1947, which was a hit on Broadway and earned him his first Tony Award for Best Author. His major peak of success followed quickly with "Death of a Salesman" in 1949, which won multiple awards, including the Pulitzer Prize for Drama, several Tony Awards, and became an iconic American play. These works established him as a leading figure in American theater by the late 1940s.

Key Milestones in Miller's Success

• 1947 : "All My Sons" became a Broadway hit, ran for 328 performances, won the New York Drama Critics’ Circle Award, and earned Miller his first Tony Award.

• 1949 : "Death of a Salesman" opened on Broadway, won the Pulitzer Prize, Tony Awards (including Best Play, Best Direction, and Best Author), and the New York Drama Critics’ Circle Award, solidifying his national fame.

• 1953 : "The Crucible" premiered and also won a Tony Award, continuing his success in American theater.

Before these successes, Miller had some early works with mixed results, such as his 1944 debut "The Man Who Had All the Luck," which was poorly received, but he persisted and rose to acclaim starting in the mid-1940s.

Thus, Arthur Miller was considered a success primarily starting in 1947 with "All My Sons" , fully cemented by 1949 with "Death of a Salesman".
