[1] He was born in Dublin, and joined Sinn Féin and Fianna Éireann while still at school.
In 1924 he was the first Administrative Officer appointed by the new Free State civil service, where he worked mainly in the Department of Finance.
Together with Frank Duff he formed the Pillar of Fire Society in 1942, for Catholic-Jewish dialogue, after rumours about the killing of Jews in Europe starting coming through to Ireland.
He presented a paper at the first meeting, helped by a Jewish colleague and friend, Laurence Elyan.
