Andre Gide, on the right, and Marc Allegret in a Sanga Village in the Congo, 1925. It is this trip that forms the basis for the book "Travels in the Congo" which was instrumental in changing certain practices of the French government with regard to the countries of Congo, Zaire, and the Central African Republic. Marc Allegret was the son of Elie Allegret who was best man at Gide's wedding. Of Allegret's five children, Andre Gide adopted Marc.
