Louis Auguste Jules Frans De Jaegher was born in Nieuwpoort, Belgium, on 30 July 1908.
He was assigned for his internship to Baseka Bongwalanga Territory in Lulonga District, Équateur Province.

Between then and 20 April 1947 De Jaegher took only three short leaves totalling nine months, two in South Africa and one in Kivu.
[4] On 1 July 1955 De Jaegher was appointed provincial commissioner, and reached Luluabourg by air plane on 26 September 1955 with his family.

Dequenne, the first burgomaster M. Hentgen and the Provincial Director of Indigenous Affairs met on 29 June to discuss the Lulua-Baluba conflict and the Lulua claims.
It was stolen that evening, communicated to activists of the Muluba Solidarity Movement, then put back where it had been found.
