Tomás de Bhaldraithe

Who was Tomás de Bhaldraithe?

Tomás de Bhaldraithe was an Irish language scholar and lexicographer born Thomas MacDonagh Waldron in Limerick. He moved to Dublin with his family at the age of five. He was named after Thomas MacDonagh one of the signatories of the Proclamation of the Irish Republic, who had been executed after the Easter Rising earlier that year. He adopted the use of the Irish language version of the name in both Irish and English. He received his second level education at Belvedere College in Dublin.

He is best known for his English-Irish Dictionary, published in 1959.

His stance on standard forms and spellings was supported by Éamon de Valera despite opposition from traditionalists in the Department of Education, and the work is widely seen as an important benchmark in Irish scholarship.

In 1960 he was appointed professor of modern Irish language and literature in University College Dublin, where he developed an impressive archive of material on Irish dialects. Much of the material in this archive was later used as the basis of Niall Ó Dónaill's Foclóir Gaeilge-Béarla, published in 1978, for which he was consulting editor. Also during the 1970s, de Bhaldraithe translated the Irish language diary of Amhlaoibh Ó Súilleabháin into English. It was then published by Mercier Press as, "The Diary of an Irish Countryman."
