Dr. Eric Gallagher was the head of the Methodist Church in the Republic of Ireland, who was one of the group of Protestant churchmen who met with IRA/Sinn Féin representatives in Feakle, County Clare in the 1970s to unsuccessfully try to broker a peace. The meeting was broken up by the Irish Police, but the fugitive IRA men had already left. He is the subject of "Peacemaker" by author Dennis Cooke. Wikipedia
