Lorcan Collins was born and raised in Dublin. A lifelong interest in Irish history led to the foundation of his hugely-popular 1916 Walking Tour in 1996. He co-authored The Easter Rising: A Guide to Dublin in 1916 (O'Brien Press, 2000) with Conor Kostick. His biography of James Connolly was published in the 16 Lives series in 2012. He is also a regular contributor to radio, television and historical journals. 16 Lives is Lorcan's concept and he is co-editor of the series with Ruan O'Donnell.
