P. S. O'Hegarty

Patrick Sarsfield O'Hegarty (, 29 December 1879 – 17 December 1955) was an Irish writer, editor and historian and a member of the Supreme Council of the Irish Republican Brotherhood.

Life He was born at Carrignavar, County Cork, to John and Katherine (née Hallahan) Hegarty. His parents' families had emigrated to the United States after the Great Famine, and his parents married in Boston. His father was a member of the IRB.

He was educated at North Monastery CBS, where he formed an enduring friendship with Terence MacSwiney. In 1888 his father died of tuberculosis, aged 42. Left destitute, his mother pawned her wedding ring to pay for an advertisement looking for work, and eventually became a cook. In 1905, he was elected secretary of the local Dungannon Club, which drew in as members Robert Lynd, Herbert Hughes and George Cavan. In 1907, as Sinn Féin's London Secretary, he approved and signed the membership card of Michael Collins; he later became friend and mentor to Collins.

In 1913 he was re-posted to Queenstown (present-day Cobh) as postmaster. He continued editing nationalist newspapers such as Irish Freedom (founded in 1910, it was suppressed in December 1914 on account of its seditious content) and An tÉireannach (1913) and joined the Irish Volunteers. At the outbreak of war he was moved to Shrewsbury, probably on account of his political activities. In 1915 he married Wilhelmina "Mina" Smyth, a schoolteacher and suffragist, and was then moved to Welshpool, Montgomeryshire. In the aftermath of the 1916 Rising, he was opposed to physical force. In 1918 he refused to take the British Oath of Allegiance and resigned his position in the Post Office.

O'Hegarty felt that the Abbey Theatre was "doing good for Ireland" and supported W. B. Yeats against attacks from Arthur Griffith and like-minded Nationalists. He opposed the extremist views of D. P. Moran, who sought a Roman Catholic Irish-speaking Ireland.

He was Secretary of the Irish Department of Post and Telegraphs from 1922 to 1945. He was elected a member of the Irish Academy of Letters in 1954.

His son, Seán Ó hÉigeartaigh, was a founder of the Irish-language publishing house Sáirséal agus Dill. His daughter Gráinne, a harpist, married Senator Michael Yeats, son of W. B. Yeats.
