Alan Alda (born January 28, 1936 as Alphonso Joseph D'Abruzzo) is an American actor, writer, director and sometime political activist.
He is most famous for his role as Hawkeye Pierce in the television series M*A*S*H. In the 1970s and 80s he was viewed as the archetypal "sensitive male", though in recent years he has appeared in roles which counter that image.
