In 1929, the position of General Secretary of the G.A.A. became vacant for the first time in almost 30 years. The Governing Body of the GAA, the Central Council, decided that applicants must be members of the Association for a minimum of five years, must be under 40 years of age, and would have to undergo a qualifying examination consisting of Irish (oral and written), English, arithmetic and book-keeping. The chosen candidate would act as both the Secretary of the GAA and the Manager of Croke Park; be paid a salary of £300 (rising in annual increments of £10 to a maximum of £400), and be provided with a free house and electric light. There were a total of 11 applications for the post, only 9 of these attended the August 1929 examinations. After the examinations two rounds of votes were taken; on the final vote 31-year-old Padraig Ó Caoimh defeated F. Burke by 11 votes to 10. He resigned his positions at the Munster tobacco company and at the Cork County Board, and was appointed Secretary of the GAA. Within three years of his appointment his renowned organisational skills were put to the test. In 1932
Croke Park hosted both the Tailteann Games and the Eucharistic Congress. The Eucharistic Congress in particular required a great deal of organisation with Ó Caoimh responsible for up to 2,000 stewards. By far the most controversial episode in Ó Caoimh's 35-year career was the removal of
Douglas Hyde,
President of Ireland, as a Patron of the Association in 1938. Hyde broke the GAA's ban on "foreign games" by attending an international soccer match in Dublin. The question raised by
Éamon de Valera in 1946 was whether Ó Caoimh should have warned Hyde on the implications of attending a soccer match and thus allowing Hyde to retire quietly as a Patron. One of Ó Caoimh's key achievements was the staging of the 1947 All-Ireland Senior Football Final in the Polo Grounds, New York. One has to remember that in 1947 Europe, and America, were still recovering from
World War II, air travel was still relatively novel and communications were still primitive. In the space of five months Ó Caoimh oversaw the transfer of the All-Ireland Final to America and its radio broadcast back to Ireland. While the Polo Grounds Final achieved its ultimate aim of rejuvenating the Association in America, Ó Caoimh, for the rest of his tenure, had to spend a disproportionately high amount of his time organising the GAA in America. The post-1947 relationship between the GAA in Ireland and the GAA in New York was, at times, fragile. A number of experiments were tried such as the St. Brendan Cup Competition, the inclusion of New York in the National League Finals and the initiation of a World Championship Series. Yet there was a constant degree of disharmony either within the American GAA itself or between Ireland and America. Ó Caoimh patiently and diplomatically sought, and tested, solutions that would placate both parties. One lasting legacy of the Ó Caoimh era that is still evident today is the drive he initiated to have a GAA-owned pitch in every parish. In 1957 a Parks Committee (Coiste na bPáirc) was formed to advise on a unified plan for the development of grounds. From this Parks Committee came the 'Grounds Plan' which saw grounds being purchased and refurbished, with grants from the Central Council, on a phased basis i.e. Provincial Grounds in phase one of the plan, County Grounds in phase two etc. In paying tribute to O'Caoimh after his death Alf Ó Muiri, President of the Association, stated that "in 1929 there were 1,500 clubs, in 1963 there were more than 3,000…the number of grounds owned in 1929 must have been very few, there are now close on 400 grounds owned and properly vested in the Association". Ó Caoimh continued to work through a long period of poor health (he underwent four major operations between 1944 and 1963) and the Central Council acted to reduce his workload and employed new staff, including his successor-to-be
Seán Ó Síocháin. Ó Caoimh died in May 1964 (aged 66), a few months before completing 35 years as Secretary of the GAA. An obituary in
The Irish Times stated that "under his administrative genius the GAA became by far the strongest sports organisation in the country and reputedly the biggest amateur association of its kind in the world. During his term of office, its membership grew to the huge proportions of today, including powerful branches in the United States, Britain, Australia and Africa; imposing stadia, of which Croke Park was his special care. Without his ability to co-ordinate plan and inspire, only a fraction of this extraordinary progress could have been achieved." ==Páirc Uí Chaoimh==
