Joan Denise Moriarty, Irish ballet dancer, choreographer, teacher of ballet and traditional Irish dancer and musician, dies on January 24, 1992. She is a key figure in the development of both amateur and professional ballet in Ireland.

Little is known of Moriarty’s early life. Her year of birth is estimated between 1910 and 1913 but no documentation has been found. The place of her birth is also unknown, and even the country is uncertain. She grows up as the daughter of Michael Augustus Moriarty, an alumnus of Stonyhurst College and contemporary of Sir Arthur Conan Doyle, and his wife, Marion (née McCarthy). The Moriartys are originally from Mallow, County Cork, where her grandfather John Moriarty was a successful solicitor.

Moriarty is brought up in England. She studies ballet until her early teens with Dame Marie Rambert. She is an accomplished Irish step-dancer and traditional musician, and becomes the champion Irish step-dancer of Britain on April 24, 1931. She also wins a swimming championship. She is a member of the Liverpool branch of the Conradh na Gaeilge.

In the autumn of 1933 Moriarty returns with her family to their native Mallow in County Cork. In 1934, she sets up her first school of dance there. From 1938 she also gives weekly classes in Cork in the Gregg Hall and Windsor School. During the 1930s she takes part in the Cork Feis, annual arts competitions with a focus on traditional dance and music, competing in Irish step-dancing, warpipes and operatic solo singing. She performs on the warpipes in various public concerts and gives at least two broadcasts. In 1938 she is invited by Seán Neeson, lecturer in Irish music at University College Cork, to perform at a summer school which the Music Department organises for primary school teachers.

Moriarty’s mother dies in February 1940. The following November she moves to Cork where she sets up the Moriarty School of Dancing. The early years during the war are very difficult financially. In the early 1940s she performs with her dancers in musicals and variety shows at the Cork Opera House.

In 1945 the composer Aloys Fleischmann invites Moriarty to perform in his Clare’s Dragoons for baritone, war pipes, choir and orchestra, which had been commissioned by the national broadcasting company, Radio Éireann, for the Thomas Davis centenary. Moriarty agrees, on condition that his Cork Symphony Orchestra would play for her Ballet Company’s annual performances, which marks the beginning of a lifelong collaboration.

Branches of the Moriarty School of Dance are established in Bandon, Clonmel, Fermoy, Killarney, Mallow, Tralee, Waterford, and Youghal. Moriarty bequeaths her Cork school to Breda Quinn, a long-standing member of the Cork Ballet Company, who runs it with another Moriarty student, Sinéad Murphy, who creates a new dance school, Cork School of Dance, after Breda’s death in 2009.

Moriarty founds the Cork Ballet Group in 1947, the members recruited from her school. It gives its first performance in June of that year at the Cork Opera House. In 1954 the group is registered as a company under the name “Cork Ballet Company.” The company’s final season is 1993, the year following Moriarty’s death.

Irish Theatre Ballet is founded by Moriarty in the summer of 1959, and gives its first performance in December 1959. It is a small touring company of 10 to 12 dancers, which travels all over Ireland, going to some 70 venues annually with extracts from the classical ballets, contemporary works and folk ballets. In an attempt to resolve the constant financial difficulties, the Arts Council in 1963 insists on a merger with Patricia Ryan’s Dublin National Ballet. The amalgamation does not bring a solution to the financial problems besetting both companies and, after one joint season, the amalgamated company, Irish National Ballet, has to be disbanded in March 1964.

In 1973, the Irish government decides to fund a professional ballet company, the Irish Ballet Company, and entrusts it to Moriarty. Like Irish Theatre Ballet, it is a touring company which travels all over Ireland in two annual seasons. The company has a number of striking successes between 1978 and 1981. In 1983 the name of the company is changed to Irish National Ballet. The severe recession in Ireland during the 1980s and shrinking funds force the Irish National Ballet to disband in 1989.

Moriarty spends almost 60 years working for ballet in Ireland. Her amateur Cork Ballet Company is still the longest-lasting ballet company the country’s history. Her two professional touring companies bring ballet to all parts of Ireland for 21 years. She receives numerous awards for her work, among them an honorary doctorate from the National University of Ireland in 1979.

During the last years of her life, Moriarty suffers ill-health, but continues her work with the Cork Ballet Company, bringing the shows to towns in the county. She dies on January 24, 1992 in Dublin.
