Biography: Martin Sheen (born August 3, 1940) is an American actor. Sheen was born Ramón Estévez in Dayton, Ohio. He lived on Brown Street in the South Park neighborhood, and was one of 9 brothers. He attended Chaminade High School. A Roman Catholic, he adopted the stage name Sheen in honor of priest and theologian Fulton J. Sheen. Martin Sheen is of Irish and Spanish descent.
Sheen had wanted to act since he was very young, but his father disapproved. He deliberately flunked out of the University of Dayton so that he could pursue his goal. (He has, however, credited the Marianists at that university as a major influence on his public activism.) His first major role was on Broadway, in The Subject Was Roses, which he recreated in the 1968 film of the same name. He did not receive another important part until 1973, when he starred with Sissy Spacek in the crime drama Badlands.
In 1974, Sheen received an Emmy Award nomination for Best Actor in a televsion drama for his portrayal of Pvt. Eddie Slovik in the made-for-television film, The Execution of Private Slovik. The film told the World War II story of the last American soldier to be executed for desertion. It was his performance in this film that ultimately led to Francis Ford Coppola choosing him for a starring role in 1979's Apocalypse Now which gained him wide recognition. On the set of Apocalypse Now, Sheen admitted that he wasn't in the greatest shape and was using drugs heavily. On location Sheen had a heart attack and crawled out to a road for help.
Sheen married fellow actress Janet Templeton in 1961, and the two have four children, all actors:
Ramón Estevez Jr.
Martin Sheen is no stranger to politics, both professionally and in real life. He has played U.S. President John F. Kennedy (in the miniseries Kennedy - The Presidential Years) and fictional Democratic president Josiah Bartlet in the acclaimed television drama The West Wing. Sheen is known for his robust support of "liberal" political causes, and has been arrested 63 times for protesting against issues such as United States military actions. Sheen has resisted calls to stand for office, saying "There's no way that I could be the president. You can't have a pacifist in the White House ... I'm an actor. This is what I do for a living."
Although generally liberal in his political beliefs Sheen is in fact pro-life and is a member of Consistent Life, a group promoting the Consistent Life Ethic which speaks out against abortion, the death penalty, euthanasia and war. He has also supported causes for PETA.
In 2004, Sheen campaigned for Democratic presidential candidate Howard Dean along with fellow actor Rob Reiner.
Sheen has a star on the Hollywood Walk of Fame, at 1500 Vine Street.
Sheen recently expressed a wish to return to education. "My plan is to read English literature, philosophy and theology in Galway, Ireland, where my late mother came from and where I'm also a citizen.", he said.  A spokeswoman for National University of Ireland (NUI), Galway, said: "Obviously we would be quite happy to accommodate him. This is the first I have heard of it."
He has said that he was greatly influenced by the actor James Dean.
Actor Joe Estevez is the younger brother of Martin Sheen.
