Broadcaster and author Joe Duffy was the presenter of Ireland's most popular daily radio programme, Liveline, on RTÉ Radio 1 for more than 25 years. He also presented Liveline: Callback and latterly The Meaning of Life on RTÉ One Television.

Born in Dublin's Mountjoy Square and reared in Ballyfermot, he published his bestselling memoir, Just Joe, in 2011.

In 2015, his original research on the children killed during the Easter Rising of 1916 unearthed, for the first time, information on the forty children who died violently that week. His books have been critically acclaimed: Children of the Rising won the Non-Fiction Book of the Year award at the Irish Book Awards in 2015, and Children of the Troubles, co-authored with Freya McClements, won Best Irish-Published Book of the Year at the Irish Book Awards in 2019.

Following a distinguished career in broadcasting, Duffy retired from RTÉ in 2025, having become one of Ireland's best-known and most trusted broadcasters.
