A member of the Fang ethnic group,[5] born in Lambaréné,[2] Nan Nguéma studied in Paris and obtained a Ph.D. in economics; he also received degrees in political science and business and public administration.

Later, in 1968, Nan Nguéma was appointed as Gabon's permanent representative to the United Nations Office at Geneva, and he began working as an executive at the French oil company Elf Aquitaine in November 1970.[1]
Nan Nguéma was adviser to the executive director of the International Monetary Fund from 1972 to 1975. Subsequently, he was Gabon's representative to the OPEC Executive Commission Board from 1975 to 1976 and deputy director-General of the Elf Gabon oil company from 1976 to 1981.[1]

Amidst the wave of democratization that swept Africa beginning in 1990, Nan Nguéma joined the Gabonese opposition and became vice-president of the Gabonese Progress Party (PGP) when it was founded in March 1990.[12] [13] He subsequently left the PGP to found the Liberal Democratic Party (PLD) in mid-1992.[12] In late September 1993, he announced that he would stand as a candidate in the December 1993 presidential election.[14] In the election, he officially placed 10th with 0.86% of the vote.[15] [16] Nan Nguéma was subsequently the President of the Congress for Democracy and Justice (CDJ) until 2000, when the party was restructured at its Second Ordinary Congress and Jules-Aristide Bourdes-Ogouliguende assumed the leadership as its Secretary-General.[16]
Nan Nguéma was arrested on 29 November 2004[17] for illegal arms possession after assault rifles were allegedly found buried at his property in Port-Gentil.[18] According to Nan Nguéma and his lawyer, the weapons were legally obtained for protection during the turbulent political struggle of the early 1990s and he had no intent to use them aggressively.[10] [19] Bourdes-Ogouliguende denounced the arrest and alleged that it was part of an attempt to brand the CDJ as a terrorist organization.[18]
