In 1920 Bertrand began working on manpower policy for
Forminière, a powerful colonial company that was very active in the
Kasaï region. His first cousin Jean Jadot was the chairman. Forminière was notable for its opposition to forced recruitment of African workers. In 1921 Bertrand became president of the Kasaï Labor Exchange, and in 1927 he became president of the Katanga Labor Exchange. These two private organizations, sanctioned by the authorities, regulated recruitment of Congolese workers by European employers. Betrand became known as an expert on the Congo in some official and political circles. In 1922 the House of Representatives elected Bertrand as a member of the Colonial Council, a position he held until the end of his life. In 1924 he reported on the Congolese workforce to the Belgian Colonial Congress. He became a member of the Commission for the Study of Manpower in the Belgian Congo in 1924. He became an associate member of the Royal Belgian Colonial Institute in 1930, and a full member in 1931. In 1930 a labor commission under Major Alphonse Cayen was appointed after missionaries had complained about the effect of rapid economic development on African Societies. The commission made field investigations in 1931-32 and issued reports on each of the four provinces, and a general report. Bertrand wrote the report on the Orientale Province, which was much the most detailed and seems to have had a strong influence on the overall recommendations in the general report. A basic assumption, as in other reports, was that the Africans were a resource like wild animals. Quotas had to be set and enforced on how many Africans could be recruited so the general population could be maintained at a healthy level. Betrand wrote a 1932 report that strongly criticized the practices at the Kilo-Moto gold mines, leading to a heated argument with General
Georges Moulaert, the head of the company and an influential person in the colonial establishment. Bertrand became increasingly viewed as a gadfly for his criticism. In 1939 Bertrand married
Jeanne Tercafs, a young sculptor 28 years younger than him, who received artistic grants for several trips to the
Mangbetu country in the Congo between 1935 and 1940. Bertrand was also interested in African arts, and was a member of the commission for the protection of indigenous arts and crafts, which had been created in 1935. He presented the work of his future wife, Jeanne Tercafs, to the Royal Colonial Institute from 1937. During
World War II Bertrand was among those Belgians who considered that German victory was inevitable, and they should make the best they could of the new situation. As a result, he associated himself with leaders of the
Kolonialpolitisches Amt, the colonial service of the
Nazi Party. His wife died prematurely in 1944. After the liberation of Belgium he was investigated and then charged in July 1945, although he was not arrested. He resigned from his position at the Royal Colonial Institute. He died in
Uccle on 20 September 1946, the day after leaving the Colonial Council. ==Notes==
