Source-derived summary

Rúaidhrí de Valera (3 November 1916 – 28 October 1978) was an Irish archaeologist most known for his work on the megalithic tombs of his country. He was the son of Éamon de Valera and Sinéad de Valera.

Early studies

De Valera took a Bachelor of Arts degree in Celtic studies from University College Dublin in 1939, before serving briefly in the Irish Army and then lecturing at the National University of Ireland at Maynooth for one year until 1943. He then studied for an MA in archaeology, writing his thesis on the prehistoric tombs of County Clare.

Work

In 1947, de Valera became the Archaeological Officer for Ordnance Survey Ireland which permitted him to develop the Survey of the Megalithic Tombs of Ireland project. He went on to write significant papers on Irish prehistory which contributed to his doctorate, awarded in 1954.

In 1957, de Valera was appointed Chair of Celtic Archaeology at University College Dublin where he worked to enlarge the department whilst continuing to publish on Irish chamber tombs, especially the Court cairns which he proposed first developed in the west of the country.

De Valera later excavated at the Mound of the Hostages at Tara.

He died suddenly on 28 October 1978, while visiting the Fermanagh County Museum in Enniskillen, Northern Ireland.

Editorial summary

Begin with the source’s own compact description: “Rúaidhrí de Valera” is irish archaeologist (1916-1978). The dossier treats that line as a proposition to test through Rúaidhrí, Valera and Irish, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1916, 1978, 1939, 1943—that can be checked directly. The authority record carries competing date values—1916-01-01, 1916-11-03—which should remain separate until their references and qualifiers are resolved. For this dossier, Rúaidhrí, Valera and Irish is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “irish archaeologist (1916-1978)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 31, 2026.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
