Stacy Keach, the stage and screen actor best known as television detective Mike Hammer, has died aged 85 at his home in Magdalenka, Poland. His wife, Malgosia Tomassi Keach, announced the death in a statement on Tuesday, saying he died after a long and difficult battle with a serious heart condition and heart failure.

Born Walter Stacy Keach Jr. on 2 June 1941 in Savannah, Georgia, Keach grew up in a theatrical family and built a career spanning more than six decades across theatre, television and film. He became widely known for playing hard-boiled private eye Mickey Spillane's Mike Hammer on television, a role he returned to across several series and films.

A career across stage and screen

Keach was admired as much for his stage work as for his screen roles. He played Shakespearean leads on both sides of the Atlantic, took the title role in the film Fat City, and later played the novelist Ernest Hemingway. Younger audiences knew him from Prison Break, The Blacklist and Blue Bloods. He had become a Polish citizen in 2015.

His health had been fragile for years. Keach suffered a heart attack on stage in Chicago in June 2017, and his wife said his final years were marked by a serious heart condition and heart failure. He died peacefully at home, his wife said.

Tributes to a working actor

Keach is survived by his wife, Malgosia Tomassi, a Polish-born actress who appeared alongside him in several of his Hammer productions. Colleagues and fans remembered him as a versatile character actor equally at home in classical theatre and in tough-guy screen roles, with a career that ran from the stages of New York and London to some of American television's most familiar dramas.
