Cronin retired from domestic politics at the 1981 general election, having been elected to the European Parliament for Munster, for a five-year term in 1979.
He was born in Currabeha, Fermoy, County Cork, the son of Alice Mulcahy and Sean Cronin.[3] His uncle, Arthur Mulcahy, was a member of the Irish Republican Army, and was shot by British forces during the Irish War of Independence on 22 March 1921.[4] Jerry Cronin died on 19 October 1990, having suffered with Parkinson's disease.
