Lieutenant General Dermot Earley DSM, high-ranking military official in Ireland and with the United Nations, is born on February 24, 1948, in Castlebar, County Mayo. He is the Chief of Staff of the Defence Forces from 2007 to 2010.

Earley is educated at Gorthaganny National School, where his father Peadar is a principal teacher, and later attends St. Nathy’s College in Ballaghaderreen, County Roscommon.

Earley first joins the Roscommon minor football team in 1963, at the age of fifteen. In that year, his side reaches the Connacht minor final, losing to Mayo. Two years later, in 1965, he lines out in a second Connacht minor decider. Five-in-a-row hopefuls Mayo are beaten by Roscommon, giving him a Connacht Minor Football Championship title. Roscommon are later defeated in the All-Ireland semi-final. He also plays under-21 hurling with Roscommon. In 1969, he plays in the All-Ireland under-21 final where Roscommon faces Kildare, however Kildare wins on the day.

Earley is only seventeen years-old when he makes his senior debut for Roscommon in 1965. Over the next fifteen years, Roscommon wins four Connacht Senior Football Championship titles. In 1985, he sustains a fractured jaw in the Connacht semi-final against Galway, with many expecting it to end his career. He confounds everybody and lines out in the Connacht final against Mayo two weeks later. In spite of kicking six points, Mayo still triumphs by 2–11 to 0–8. At the age of thirty-seven, he decides to retire from inter-county football.

During the 1990s, Earley manages both the Roscommon county football team (1992-94) and the Kildare county football team (1994-96).

After completing his Leaving Certificate in 1965, Earley joins the Defence Forces as a cadet and is commissioned in 1967. His first posting is as a platoon commander in the Recruit Training Depot at the Curragh Camp and, in 1969, he is appointed an Instructor at the Army School of Physical Culture (ASPC). Two years later, in 1971, he obtains a specialist diploma in physical education at St. Mary’s College, Twickenham.

Earley’s service record includes overseas service with the United Nations Truce Supervision Organization (UNTSO) in 1975, Adjutant to the 52nd Infantry Battalion of the United Nations Interim Force in Lebanon (UNIFIL). From 1987 to 1991, he serves as deputy military adviser to UN secretary general Javier Pérez de Cuéllar and Battalion Commander of the 81st Infantry Battalion UNIFIL in 1997. While serving with the UN up to 1991 he is a member of negotiating teams dealing with the Iraqis and Kuwaitis and is a key adviser during the setting up of the UN’s mission in Kuwait – Unikom. He is involved in negotiating an end to the Angolan Civil War. He is a graduate of the Royal College of Defence Studies, London (2001), and holds a Master of Arts (Hons) in peace and development studies from the University of Limerick (1999). He undertakes the Ranger Course in the Defence Forces, which leads to the establishment of special operations training and the establishment of the Army Ranger Wing (ARW). He is the last serving member of that course.

Earley is appointed school commandant of the ASPC. In 1991, he is appointed an instructor at the Command and Staff School of the Military College and in 1994-95 he helps establish the United Nations Training School Ireland (UNTSI) in the Military College.

On April 18, 2010, Earley indicates he plans to retire from the Defence Forces due to ill health. He is awarded a Distinguished Service Medal with Honour from Taoiseach Brian Cowen. His resignation is accepted on June 9, 2010, and one of his previous deputies, Major General Sean McCann, is appointed Chief of Staff.
