Séamus Ó Braonáin (Jimmy Brennan) (1881–1970) was an Irish sportsman and high-ranking public servant, founding father of the women’s team field sport of camogie in 1904 (based on the men's field sport of hurling), third Director General of Raidió Éireann 1940-47, and winner of four All-Ireland Senior Football Championship medals with Dublin in 1902, 1906, 1907 and 1908.
He went to school in Ballyouskill, near Ballyragget, County Kilkenny, where his teacher was the father of Pádraig Puirséil, and then came to Dublin to study in St Mary's College, Rathmines, captaining their Senior Cup side. He joined the Craobh Céitinn branch of the Gaelic League in 1902 and became branch secretary.
He was attached to the department of education until 1936 when he became secretary for the commission of Irish in the Civil Service and deputy director of broadcasting of Raidio Éireann and eventually succeeded TJ Kiernan as Acting Director in 1940 and Director of Broadcasting from May 1942, serving until 1947. When he retired Eamonn Andrews wrote:
At least one radio scribe will miss his consideration and his patience. I am wondering if he will now acquire the ability to listen with pleasure and detachment to Raidio Eireann without wondering if an announcer is going to develop convulsions or an artiste suddenly discard his script and talk chattily of things that must not be talked about chattily.”
