Biographical History

Born in Waterford, Ireland, Hearne studied at University College Dublin where he was awarded a Bachelor of Arts in 1915 and his LLB (Bachelor of Laws) in 1919. Called to the Bar in 1919, Hearne began his legal career practicing on the Leinster Circuit, which included his home county.

After the end of the Irish Civil War in 1923 he entered the Attorney General’s office as Assistant Parliamentary Draftsman, working there until he joined the Department of External Affairs as its first legal advisor in 1929. For the next decade Hearne was a participating member of many delegations to international conferences on law and a regular member of Ireland’s delegation to the League of Nations’ annual assembly. Hearne’s lasting contribution to modern Ireland is his participation in the drafting of the Irish Constitution of 1937.

His career as diplomat continued in 1939 with his appointment to Canada as Ireland’s first High Commissioner to Ottawa. There he defended Ireland’s neutral position in World War II through his high-level contacts with Canadian politicians, including the Prime Minister, William MacKenzie King.

In March 1950 Hearne was appointed Ireland’s first Ambassador to the United States of America, a post he held until his retirement in November of 1960. As a critic of the partition of Ireland, Hearne used his tenures in the United States and Canada to inform and educate audiences on Ireland’s domestic and international affairs.

Hearne’s final international role was in Nigeria and Ghana, serving as a parliamentary draftsman and legal consultant to the governments of both states from 1960-1969.

John Hearne married Monica Mary Martin (1908–1979) in 1930.

John Hearne died in Dublin, Ireland on 29 March 1969.
