Joseph McGrath (12 August 1888 – 26 March 1966) was an Irish politician and businessman. He was a Sinn Féin and later a Cumann na nGaedheal Teachta Dála (TD) for various constituencies; Dublin St James's (1918–1921), Dublin North West (1921–1923) and Mayo North (1923–1924), and developed widespread business interests. Political career McGrath was born in Dublin in 1888. By 1916 he was working with his brother George at Craig Gardiner & Co., a firm of accountants in Dawson Street, Dublin. He worked with Michael Collins, a part-time fellow clerk and the two struck up a friendship. In his spare time McGrath worked as secretary for the Volunteer Dependents' Fund. He soon joined the Irish Republican Brotherhood. He fought in Marrowbone Lane in the 1916 Easter Rising. McGrath was arrested after the rising, and jailed in Wormwood Scrubs and Brixton prisons in England. In the 1918 general election, he was elected as Sinn Féin TD for the Dublin St James's constituency, later sitting in the First Dáil. He was also a member of the Irish Republican Army, the guerrilla army of the Irish Republic, and successfully organised many bank robberies during the Irish war of Independence (1919–1921), where a small percentage of the proceeds was retained as a reward by him and his fellow-soldiers. During this time he was interred briefly at Ballykinlar Internment Camp. He escaped by dressing in army uniform and walking out of the gate with soldiers going on leave. He was eventually recaptured and spent time in jail in Belfast. In October 1921 McGrath travelled with the Irish Treaty delegation to London as one of Michael Collins' personal staff. When the Provisional Government of Ireland was set up in January 1922, McGrath was appointed as Minister for Labour. In the Irish Civil War of 1922–1923, he took the pro-treaty side and was made Director of Intelligence, replacing Liam Tobin. In a strongly worded letter, written in red ink, McGrath warned Collins not to take his last, ill-fated trip to Cork. He was later put in charge of the police Intelligence service of the new Irish Free State, the Criminal Investigation Department or CID. It was modelled on the London Metropolitan Police department of the same name, but was accused of the torture and killing of a number of republican (anti-treaty) prisoners during the civil war. It was disbanded at the war's end; the official reason given was
