Source-derived summary

Edward (Éamon) T. Hanrahan (1917 – 30 November 2012) was an Irish civil engineer, Associate Professor of Civil Engineering, and Head of department in the School of Civil, Structural and Environmental Engineering at University College Dublin (UCD). Owing to his contributions to geotechnical engineering education and practice in Ireland, a biennial lecture at UCD's Geotechnical Society is named in his honour.

Hanrahan undertook studies and research on soil mechanics and foundation engineering, particularly on soft soils such as peat. In 1955, he created the first postgraduate soil mechanics course in for students in Ireland. He published work in Irish and British journals including Géotechnique, and published several works on peat and glacial tills which continue to be cited in soil mechanics and geotechnical engineering research.

Early life and education

Hanrahan was born in Limerick City in 1917. He attended local primary and secondary schools before studying engineering at UCD. He was awarded a BE degree in Civil Engineering in 1939.

Career

After working in England during the 1940s, Hanrahan returned to Ireland and joined the faculty at UCD in 1948, where he remained until his retirement in 1987. He pursued interests in soil mechanics and foundation engineering from early in his career. Hanrahan was awarded an ME degree in 1946, a PhD in 1954, and a DSc in 1983.

Editorial summary

“Éamon Hanrahan” enters the record as irish geotechnical engineer and professor of soil mechanics. Crown Archives preserves that source wording while asking what Éamon, Hanrahan and Irish can confirm, complicate or overturn.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1917, 2012, 1955, 1939—that can be checked directly. The linked authority record independently contributes the date 1917-01-01. Its strongest next move is a source search built around Éamon, Hanrahan and Irish.
Editorial analysis

Why this record matters

“Éamon Hanrahan” is worth following because a concise public description often conceals a longer documentary argument. Here, Éamon, Hanrahan and Irish provides the most credible route into that argument.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q124173117. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1917, 2012, 1955 and 1939.

Critical limits

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. 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.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
