Irish playwright whose innovative plays captured the human dimension of the religious conflict in Northern Ireland.

Born into a working-class Protestant family, Parker won a scholarship to Queen's University, Belfast (B.A., 1963; M.A., 1965), where he studied poetic drama. He taught English in the United States at Hamilton College, Clinton, N.Y. (1964–67), and at Cornell University (1967–69). In 1969 he returned to Belfast and was a rock-music columnist for The Irish Times while writing plays for the theatre, for radio—including Minnie and Maisie and Lily Freed (1970) and The Iceberg (1975)—and for television—including Catchpenny Twist (1977) and Iris in the Traffic, Ruby in the Rain (1981). His first popularly received work for the stage, Spokesong, opened at the 1975 Dublin Theatre Festival and was produced in London (1976) and in New York City (1979). Parker's later plays included Northern Star (1984), Heavenly Bodies (1986), and Pentecost (1987).
