He was born 25 December 1924 in
Finglas, Dublin, the fourth child among three sons and five daughters of
James Tunney, a farmer and Labour Party TD and senator, and M. Ellen Tunney (née Grimes), who both came from outside
Westport, County Mayo. He was educated at
St. Vincent's C.B.S. in
Glasnevin. He worked in the
Department of Agriculture from 1943 to 1955 and it was in this period that he studied part-time at
University College Dublin, where he took a BA in drama, English, and Irish before studying for a postgraduate qualification in Irish. From 1955 to 1962 he taught drama at
VECs in Lucan, Balbriggan, and Garretstown, before being appointed headmaster of Blanchardstown VEC in 1962. He also played at senior level for the
Dublin county team. He was on the winning side for Dublin in the 1948
All-Ireland Junior Football Championship. A snappy dresser who earned the nickname –
the yellow rose of Finglas, he was sometimes seen as pompous, a perception possibly attributable to his acting background, which once led to an audition for Dublin's
Abbey Theatre. ==Politics==
