Éamonn Mac Thomáis was an author, broadcaster, historian, Irish Republican, advocate of the Irish language and lecturer. He presented his own series on Dublin on RTÉ during the 1970s and was well known for guided tours and lectures of his beloved Dublin. He is buried in Dublin's Glasnevin Cemetery, next to Frank Ryan.

Frank Ryan was an Irish politician, journalist, intelligence agent and paramilitary activist. He first came to prominence as an Irish republican activist at University College Dublin and fought for the Irish Republican Army during the Irish Civil War. Ryan fell under the influence of Peadar O'Donnell, an advocate of socialism within Irish republicanism, which resulted in him breaking with the IRA and becoming involved with founding a new political organisation, the Republican Congress, and editing its associated newspaper, An Phoblacht.
