This book is about the celebration of the emeritus status of the Researcher Wufela and consists of four main parts: - biobibliographical elements for a better knowledge of the Emeritus Researcher;- various texts from CRESH related to the preparation of this event;- four scientific papers prepared for the occasion by the Emeritus Researcher. In these papers, André Wufela returns to his favourite research topics in both oral and written African literature, while in the very first paper, he presents his experience - testimony for more than fifty years on the functioning of scientific research and naturally takes a look at it both retrospectively and prospectively;- finally, to combine business with pleasure, a few images are included to support the ceremony.
