The unknown voice of Seán Lemass - 22 hours of lost interviews unveil the private thoughts of Ireland's most transformative taoiseach.

Lemass left no documents or autobiography. Instead, he gave 22 hours of interviews to Irish businessman Dermot Ryan in 1967 and 1968. The transcripts were handed over to The Irish Times newspaper, and excerpts from these interviews were published as a supplement in May 2018.

These revelations uncover the tensions in his relationship with long-serving Taoiseach de Valera, his aversion to the IRA, his complex relationship with Great Britain, and much more.
