One of Ó Caoimh's key achievements was the staging of the 1947 All-Ireland Senior Football Final in the Polo Grounds, New York.
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 [REF].
