Sir Louis Cools-Lartigue, OBE (18 January 1905 – 21 August 1993[1]) was a Dominican politician.
Until 1955, Cools-Lartigue was the Chief Secretary of the Windward Islands, when on 9 May he was issued a Commission by George F. Holsten appointing him to the position of Governor's Deputy.[2]
From November 1967 to 3 November 1978, Cools-Lartigue was the last Governor of Dominica.[3] [4] He was then elected Interim President and served as such from 3 November 1978 to 19 January 1979,[3] until Fred Degazon was elected President of Dominica. During a constitutional crisis stirred by the desire for democratic socialist reforms, Degazon fled to England on 10 June 1979 and Cools-Lartigue was elected by the House of Assembly as his replacement on 15 June 1979.[5] Cools-Lartigue resigned as President either the following day under family pressure,[6] or due to rioters attacking his house on 17 June 1979.[7] He was replaced as President of Dominica by Jenner Armour.
