[2] Peigneux spent his entire colonial career in the southwest of the Belgian Congo, in Bas-Congo, Léopoldville and Kasaï.
[3] In 1926 his supervisor said in an evaluation report, "This officer has the qualities needed to become an elite administrator in the short term."
He found that censuses had badly under-counted dependent women and children, and excessive numbers of Africans were being employed by the European companies and on the railway.
Peigneux showed Ryckmans examples of Kimbanguist chants, psalm-like hymns that proclaimed the glory of the pure and the confusion of the unfaithful, Black and White, when Jesus would return.
[10] Peigneux's signature as a director, and that of governor Hector Martin, appears on notes of the Central Bank of Belgian Congo and Rwanda-Burundi (Banque Centrale du Congo Belge et du Ruanda-Urundi) between 1956 and 1958.
