Sylvia Valentin Bongo Ondimba has been the wife of Ali Bongo Ondimba since 1989. She became the First Lady of Gabon following the inauguration of her husband as President of Gabon on 16 October 2009.[1] [2] She created the Sylvia Bongo Ondimba Foundation, "For the family", in January 2011 "to improve the plight of vulnerable and disadvantaged people around the world".[3] On August 30, 2023, her husband, Ali Bongo, was deposed after 14 years of rule, ending her term as First Lady and subsequently leading to her arbitrary detention.
Born in Paris on 11 March 1963, Sylvia Valentin was barely two months old when her parents were transferred to Douala for work. She is the daughter of Edouard Valentin (died 28 January 2019), a French businessman who headed the group called Omnium Gabonais d'Assurances et de Réassurances (OGAR, Gabonese Insurance and Reinsurance).[4] Edouard Valentin's wife, Evelyne Valentin, then became President Bongo Ondimba's secretary.[5]
Sylvia spent most of her childhood in Cameroon along with her siblings, before the family took up residence in Tunisia.
In 1974, after a long stay by the Valentin family in Tunisia, Sylvia and her parents decided to move to Gabon, where she received an academic and Christian education at the Libreville Immaculate Conception Institution.
In 1988, Sylvia met Ali Bongo Ondimba. They married in 1989. They have three children: Noureddin Edouard, Jalil, and Bilal, adopted by the couple in 2002. Malika is the president's first daughter from a previous relationship.
On 16 October 2009, as Ali Bongo Ondimba was elected president, Sylvia Bongo Ondimba became Gabon's First Lady.
Her grand-children are Elizabeth, Deborah and Dyah Bongo.
