Born in 1887. Plunkett was the youngest of the signatories of the Proclamation. A poet of distinction and a close associate of Thomas Mac Donagh, with whom he founded the Irish Theatre, Plunkett devoted himself unsparingly to the independence movement. He was a founder member of the Irish Volunteers and the military plans for the Rising are believed to have been largely his work. He left his sick bed to take part in the fighting in the General Post Office. He was executed on 4th May 1916.
