Ms. Louise Horne served as an Independent Senator from 1976 to 1991, making her one of the longest serving Senators in the history of the Republic of Trinidad and Tobago. Ms. Louise Horne was first appointed an Independent Senator in 1976 by His Excellency Sir Ellis Clarke. She was so successful a Senator that the President reappointed her for two further terms of office in the Senate.

Ms. Horne was awarded the honour of St. Gregory by Pope John Paul II and henceforth would carry the title Dame Louise Horne. Dame Louise was awarded the title on Sunday, November 07, 2004 for her service as a Roman Catholic to her parish community and the Catholic community of the Republic of Trinidad and Tobago.

Ms. Horne distinguished herself as a nutritionist and served as Chief Nutrition Officer in the government service, as well as in an earlier career as a teacher. In fact, one of her former pupils was calypsonian Lord Kitchener, Mr. Aldwyn Roberts.

Ms. Horne has been involved in several service organizations in Trinidad and Tobago, such as the Coterie of Social Workers, the Arima Community Welfare Council and the Trinidad and Tobago Blind Welfare Association. Dame Louise’s life has always been and continues to be oriented around service to her fellowman. In 1992 she was awarded the Trinidad and Tobago Medal of Merit—Gold, for her work in the field of dietetics and the public service. Dame Louise was also honoured on a postage stamp that commemorated the 1980s decade of women.

In her invaluable history book, the Evolution of Modern Trinidad and Tobago 2004, Dame Louise writes that she considers herself fortunate to be living during the most important era in the life of the country. At over 90 years of age she still lead an active life, which included participation at meetings of the Trinidad and Tobago Branch of the Commonwealth Parliamentary Association.

Ms. Horne passed away on March 28, 2021 aged 108.
