Thomas Maguire was born into a Catholic merchant family in Dublin on 24 January 1831 and died in London on 26 February 1889. He entered Trinity College, Dublin in 1851, graduating in 1855 as Senior Moderator in classics and philosophy. In 1861 he obtained a law studentship at Lincoln's Inn and was called to the English Bar in 1862. He practised only for a short period before returning to academic life. He was appointed to the Professorship of Latin at Queen's College, Galway in 1869. In 1880 he had the distinction of being the first Catholic to be elected to a Fellowship in Trinity after Fawcett's Act of 1873 had removed ‘religious disabilities’ at the traditionally Protestant institution. He was appointed to the Professorship of Moral Philosophy there in 1882.
