Miller died on Thursday evening after a battle with pneumonia, cancer and a heart condition, according to his assistant Julia Bolus.
A statement reads, "Mr. Miller passed away at his home in Roxbury, Connecticut, last night at 9.17 p.m. of congenital heart failure."
Most famous for his Pulitzer Prize-winning play Death of a Salesman, Miller's works criticized the growing fragmentation of American society and concentrated heavily on morality and the family.
In an interview in 1992, Miller described Monroe--whom he divorced in 1961--as "highly self-destructive" adding of their marriage, "All my energy and attention were devoted to trying to help her solve her problems. Unfortunately, I didn't have much success."
British contemporary playwright Harold Pinter has paid tribute to his friend. Describing Miller as a "wonderful chap", Pinter was "absolutely flabbergasted" to learn of his death.
He adds, "He was a great playwright and a great man--and a great friend of mine. His plays are among the finest works that have been produced in the 20th Century.
"But he was also a highly dignified and an extraordinarily formidable man, an independent man. He was so honest and a man of rare integrity in his writing."
