Joseph Campbell, Irish poet and lyricist, is born in Belfast on July 15, 1879. He writes under the Gaelic form of his name Seosamh Mac Cathmhaoil (also Seosamh MacCathmhaoil), as Campbell is a common anglicisation of the old Irish name MacCathmhaoil. He is now remembered best for words he supplied to traditional airs, such as “My Lagan Love” and “Gartan Mother’s Lullaby.” His verse is also set to music by Arnold Bax and Ivor Gurney.

Campbell is born into a Catholic and Irish nationalist family from County Down. He is educated at St. Malachy’s College, Belfast. After working for his father he teaches for a while. He travels to Dublin in 1902, meeting leading nationalist figures. His literary activities begin with songs, as a collector in Antrim, County Antrim and working with the composer Herbert Hughes. He is then a founder of the Ulster Literary Theatre in 1904. He contributes a play, The Little Cowherd of Slainge, and several articles to its journal Uladh edited by Bulmer Hobson. The Little Cowherd of Slainge is performed by the Ulster Literary Theatre at the Clarence Place Hall in Belfast on May 4, 1905, along with Lewis Purcell’s The Enthusiast.

Campbell moves to Dublin in 1905 and, failing to find work, moves to London the following year where he is involved in Irish literary activities while working as a teacher. He marries Nancy Maude in 1910, and they move shortly thereafter to Dublin, and then later to County Wicklow. His play Judgement is performed at the Abbey Theatre in April 1912.

Campbell takes part as a supporter in the Easter Rising of 1916, doing rescue work. The following year he publishes a translation from Irish of the short stories of Patrick Pearse, one of the leaders of the Rising.

Campbell becomes a Sinn Féin Councillor in Wicklow in 1921. Later in the Irish Civil War he is on the Republican side, and is interned in 1922-23. His marriage breaks up, and he emigrates to the United States in 1925 where he settles in New York City. He lectures at Fordham University, and works in academic Irish studies, founding the University’s School of Irish Studies in 1928, which lasts four years. He is the editor of The Irish Review (1934), a short lived “magazine of Irish expression.” The business manager is George Lennon, former Officer Commanding of the County Waterford Flying Column during the Irish War of Independence. The managing editor is Lennon’s brother-in-law, George H. Sherwood.

Campbell returns to Ireland in 1939, settling at Glencree, County Wicklow. He dies at Lacken Daragh, Enniskerry, County Wicklow on June 6, 1944.
