Sony Lab'ou Tansi

Tansi soon discovered that he had contracted the AIDS virus, but Lissouba's travel restrictions prevented him from going abroad to seek treatment for himself and his wife. Tansi's partner, Pierrette, died from the disease on 31 May 1995 and Tansi followed 14 days later.

After teaching for many years, Tansi moved on to government work, serving as an administrator in several ministries in Brazzaville. In the late 1980s he allied with opposition leader Bernard Kolélas to found the Congolese Movement for Democracy and Integral Development (MCDDI), a political party acting against the communist regime of President Denis Sassou Nguesso and his Congolese Labour Party. Left-wing forces succeeded in pushing President Sassou toward democracy, and former Prime Minister Pascal Lissouba returned from an extended exile and was elected President in the August 1992 elections. In that same year, Tansi was elected to parliament as a deputy for the Makélékélé arrondissement of Brazzaville, but his participation in opposition politics angered President Lissouba, and his passport was withdrawn in 1994.

In the early part of his career, Tansi continued to support himself through teaching and he worked as an English instructor at the Collège Tchicaya-Pierre in Pointe Noire while working on his first two novels and several plays. In 1979 he founded the Rocado Zulu Theatre, which would go on to perform his plays in Africa, Europe, and the United States in addition to appearing regularly at the Festival International des Francophonies in Limoges.

The oldest of seven children, Tansi was born in the former Belgian Congo, in the village of Kimwaanza, just south of the city now known as Kinshasa in the modern day Democratic Republic of the Congo. He was initially educated in the local language, Kikongo, and only began speaking French at the age of twelve, when his family moved to Congo-Brazzaville, today known as the Republic of the Congo. He attended the École Normale Supérieure d'Afrique Centrale in Brazzaville where he studied literature, and upon completing his education in 1971, he became a French and English teacher in Kindamba and Pointe-Noire. When the young teacher began writing for the theatre later that year, he adopted the pen name "Sony La'bou Tansi" as a tribute to Tchicaya U Tam'si, a fellow Congolese writer who wrote politically charged poetry about oppressive nature of the state.

Sony Lab'ou Tansi (5 July 1947 – 14 June 1995), born Marcel Ntsoni, was a Congolese novelist, short-story writer, playwright, and poet in French language. Though he was only 47 when he died, Tansi remains one of the most prolific African writers and the most internationally renowned practitioner of the "New African Writing." His novel The Antipeople won the Grand Prix Littéraire d'Afrique Noire. In his later years, he ran a theatrical company in Brazzaville in the Republic of the Congo.
