Ramón Gerard Antonio Estévez, known professionally as Martin Sheen, American actor of Spanish/Irish descent, is born in Dayton, Ohio on August 3, 1940. He first becomes known for his roles in the films The Subject Was Roses (1968) and Badlands (1973), and later achieves wide recognition for his leading role in Apocalypse Now (1979) and as President Josiah Bartlet in the television series The West Wing (1999-2006).

Sheen is born to immigrant parents, a first-generation Irish mother, Mary-Anne Phelan from Borrisokane, County Tipperary, and a Galician father, Francisco Estévez from Vigo in Galicia (Spain). He adopts the stage name Martin Sheen to help him gain acting parts from a combination of the CBS casting director Robert Dale Martin, who gives him his first big break, and the televangelist archbishop, Fulton J. Sheen. He is the father of four children (Emilio, Ramón, Carlos and Renée), all of whom are actors.

In film, Sheen has won the Best Actor award at the San Sebastián International Film Festival for his performance as Kit Carruthers in Badlands. Sheen’s portrayal of Capt. Willard in Apocalypse Now earns a nomination for the BAFTA Award for Best Actor in a Leading Role.

Sheen has worked with a wide variety of film directors, including Richard Attenborough, Francis Ford Coppola, Terrence Malick, David Cronenberg, Mike Nichols, Martin Scorsese, Steven Spielberg and Oliver Stone. He receives a star on the Hollywood Walk of Fame in 1989. In television, he has won a Golden Globe Award and two Screen Actors Guild Awards for playing the role of President Josiah Bartlet in The West Wing, and an Emmy Award for guest starring in the sitcom Murphy Brown.

Although known as an actor, Sheen also has directed one film, Cadence (1990), appearing alongside sons Charlie and Ramón. He has narrated, produced, and directed documentary television, earning two Daytime Emmy Awards in the 1980s. In addition to film and television, he has been active in liberal politics.
