Born Elizabeth Anne Kempson in County Wicklow, Ireland, she is remembered as a trade union activist and lecturer, as well as an insurrectionist in the Irish Citizen Army.

During the siege of Dublin, which lasted a week, Kempson served as a courier for Padraic Pearse and the others insurrectionists inside the General Post Office, risking her life as she dodged snipers.
