In 1963, a woman named Th. Centner published a wonderful monograph called _L'Enfant africain et ses jeux_ through the CEPSI research center, in what was then the city of Elisabethville in secessionist Katanga. Would anyone know her full first name, whether she produced other writings about what is now southern DRC, if she is still living, and if so, how I might contact her? I would like such information for a paper I am writing. ([email protected])
