Robert Briscoe (1894-1969) was born in Dublin to a Jewish family of Lithuanian extraction. He had begun a business career following his education but the events of the Easter Rising of 1916 radicalised him and compelled him to join the Irish Republican Brotherhood. Throughout the War of Independence he was a courier for Sinn Féin and the IRA shipping armaments back to Ireland where his fluency in languages and business contacts were an advantage. In addition as a Jew he was not suspected of involvement by the IRA. He opposed the Anglo-Irish Treaty and tried with greater difficulty to import arms into Ireland during the Civil War. In 1926 he became a founder member of Fianna Fáil and served as a TD from 1927 until 1965. He was also the first Jewish Lord Mayor of Dublin in 1956. His son, Ben, succeeded him as a politician upon his retirement.
