Ms. Marie-Marguerite B. Clérié
Institute of Personal and Organisational Development (IDEO) [Haiti]
Marie-Marguerite B. Clérié is a career educator who has been implementing the Montessori Method in Haiti for over forty years. She is increasingly convinced, as Maria Montessori so aptly put it, that "it is by helping to improve the individual that education can change society". In 2010, after the terrible earthquake that devastated Port-au-Prince, the capital of Haiti, destroying hundreds of schools and leaving thousands of schoolchildren homeless, she and a number of school principals founded the Association Professionnelle d'Ecoles Privées - APEP, whose acronym is FEV: Form - Educate - Live. Through this association, over forty heads of private schools have joined forces to work together to offer quality education for all, and to try to influence Haiti's education policies.
In 2013, fifty years after her father's death under the bloodthirsty dictatorship of François Duvalier, she and other sons and daughters of the victims of this dictatorship founded the Fondation Devoir De Mémoire-Haïti (FDDM-H), whose mission is to seek out the truth, denounce state violence and set the record straight on this little-known slice of Haiti's contemporary history. In addition, for almost a year now, Marie-Marguerite has been working with the Fondation IDEO to initiate training sessions for teachers and school administrators across the country, focusing on the development of a culture of love and peace in Haitian families and schools. Marie-Marguerite is, above all, a citizen committed to a just, united, generous, peaceful and unified Haiti.
