[5] Malbrant was in-charge of the Fort Lamy veterinary laboratory (set up in the late 1930s), at which he experimented with vaccines against cattle plague.
During these years he collected natural history specimens and produced more than fifty scientific reports on the African fauna.
[9] He was appointed as a member of the Provisional Consultative Assembly (based in Algiers, later in Paris), representing the 'Resistance Overseas' and as a delegate of 'Rally of the Colonies' and the Combat movement.
In July 1946 Malbrant organized the States General of Colonization (a congress of French colonists, held in Paris).
The convention gathered colonists that opposed giving French citizenships to the inhabitants of the overseas territories collectively.
[1] The dual electoral college system was abolished in late 1956, whereby Malbrant lost his possibility to get re-elected.
