James Clarence Mangan
Poet, born Dublin, Ireland, 1803; died there, 1849.
After working for several years as a clerk in a scrivener's office, and for an attorney, he began in 1831 to write verses for the Journal of the Comet Club.
He later contributed to the "Nation" inaugurated in 1842, to the "United Irishman," the "Irish Tribute," "The Irishman," and the "Dublin Irish Catholic Magazine," under fantastic signatures.
The chief editions of his poems (O'Donoghue ascribes between 800 and 900 to him) are Louise Guiney's (1897) and the Centenary edition (Dublin and London, 1903).
