Donal O'Callaghan

Donal O'Callaghan (23 June 1891 – 12 September 1962) was an Irish Sinn Féin politician and Lord Mayor of Cork from 1920 to 1924.

He was born in Peacock Lane, Cork in 1891, and was educated at Eason's Hill primary school and the North Monastery secondary school. He was a member of several Irish republican organisations, including the Ancient Order of Hibernians, the Irish Volunteers, the Irish Republican Brotherhood and Sinn Féin.

After the Burning of Cork in December 1920, O'Callaghan who had received death threats, fled to America as a stowaway on board the steamship, West Cannon. O'Callaghan returned to Cork in August 1921.

He was elected unopposed as a Sinn Féin Teachta Dála (TD) to the Second Dáil at the 1921 elections for the Cork Borough constituency. He opposed the Anglo-Irish Treaty and voted against it.

At the 1921 elections, he was elected to the House of Commons of Southern Ireland, and as the Lord Mayor of Cork, he was automatically a member of the Senate of Southern Ireland. Article 18(4) of the Government of Ireland Act 1920 precluded anyone from sitting in both Houses at once, though O'Callaghan boycotted both, sitting instead in the Second Dáil.

He stood as an anti-Treaty Sinn Féin candidate at the 1922 general election but was not elected. In June 1923, Éamon de Valera appointed O'Callaghan as the Republican envoy to the US, replacing Laurence Ginnell.

On 25 January 1924, he resigned his position as Lord Mayor of Cork. Later in 1924, he married Eibhlín Ní Shuilleabháin in London. They lived in London and later in Strasbourg before returning to Ireland in 1929. O'Callaghan secured a job as an accountant for the ESB. He died in Dublin in 1962, and is buried in Deans Grange Cemetery, Blackrock, Dublin.
