(; commonly anglicised as Tomás O'Crohan and occasionally as Thomas O'Crohan; 1855 – 7 March 1937) was a native of the Irish-speaking Great Blasket Island near the coast of the Dingle Peninsula in Ireland. He wrote two Irish-language books, ("Island Cross-Talk"), written over the period 1918–23 and published in 1928, and ("The Islandman"), completed in 1923 and published in 1929. Both have been translated into English. He is known as the "godfather" of Blasket Island writers. The 2012 translation by Garry Bannister and David Sowby is to date the only unabridged version available in English. In addition to his writings, Ó Criomhthain also provided content for Father George Clune's lexicon of the Munster Irish dialect, Réilthíní Óir. Biography It is unclear precisely when Ó Criomhthain was born. In the first sentence of An tOileánach, he states that he was born on St. Thomas's Day in 1856. However, records indicate that he was baptised on 29 April 1855. Ó Criomhthain was the youngest of 10 siblings, only five of whom survived to adulthood: four sisters, Maura, Kate, Eileen, and Nora, and a brother, Pats. Ó Criomhthain received an intermittent education between the ages of 10 and 18 whenever a schoolteacher from the mainland spent time living on the island. He married Máire Ní Chatháin on 5 February 1878. Together they had ten children, but many died before reaching adulthood: one boy fell from a cliff while hunting for a fledgling gull to keep as a pet among the chickens; others died of measles and whooping cough; their son Domhnall drowned while attempting to save a woman from the sea; others died by various other means. Máire herself died while still relatively young. Their son Seán also wrote a book, Lá dar Saol ("A Day in Our Life"), describing the emigration of the remaining islanders to the mainland and America when the Great Blasket was finally abandoned in the 1940s and 1950s. He died on 7 March 1937 at the age of 81. Writings His books — An tOileánach in particular — are considered classics of Irish-language literature, and central texts of the corpus of the Gaelic Revival. Containing portrayals of a unique way of life, now extinct, they are of great human, literary, linguistic, and anthropological interest. He began to write down his experiences in diary-letters in the years after World War I, following persistent encouragement by Brian Ó Ceallaigh from
