He was born 1 February 1919 in Church Street, Dublin, the son of John Mullen, a glassblower, and Martha Smith. He was educated at St Michan's school in Halston St., but left school at 14 to work in a butcher's after his father's death. At 16 he got a job in the Ever Ready battery factory in Portobello, where he joined the Irish Transport and General Workers' Union (ITGWU), and was elected a shop steward the following year. He was a member of the Irish Republican Army during the 1940s, but left in 1945 to join the Labour Party.[1]
He was an unsuccessful candidate at the 1951 and 1957 general elections. He was elected to Dáil Éireann as a Labour Party Teachta Dála (TD) for the Dublin North-West constituency at the 1961 general election[2] and was re-elected at the 1965 general election.[3] He did not contest the 1969 general election. He was nominated by the Taoiseach Liam Cosgrave in 1973 to the 13th Seanad.
He was a member of Dublin Corporation from 1960 to 1969. He was general secretary of the ITGWU from 1969 to 1982.[1]
